[Text] Annr~tation. This monograph presents the results of study of the~
physicochemical characteristics of aerosol particles, clouds and precip- ~
itation, consti.tuting the subject of research in a new direction in meteor-
ology atmospheric chemistry. The author describes the methods and instru-
Ments for their determination. Using a great volume of experimental data,
- th~ book gives the patterns for the entry of salt particles into the atmo-
sphere and their propagation along the coasts of different aeas and the -
characterisLics of change in the chemical composition of precipitatioa in _
relation to meteorological conditions and the advection of air masses and
cloud water, collected in different regions of the USSR, in dependencz on
the synoptic situation and type of clouds. The author evaluates the con-
tribution of clouds and the washing-out of admixtures from the layer be-
neath the clouds in formation of the chemical composition of precipitation~ -
Un the basis of data from investigation of the chemical composition of
cloud water and precipitation a global evaluation :~s made of the intensity
oF different sources of aerosols and a model of the cycling uf sea salts
~ in the atmosphere is presented. An investigation of the influence of mar-
ine aerosols on the corrosive activity of the atmosphere on sea coasts is
given as an important p~~actical applicatior.. The book is intended for spec-
ialists in the field of physics and chemistry of the atmosphere and other
related disciplines.

[Text] Annotation. This monograph glves descriptions of instruments and
the principles for operation of automatic meteorological instruments
used at the present time in the network of hydrometeorological stations
(UATGMS-4M, KRAMS, ARMS). The authors examine the design and operation
of remote meteorological instruments used in measuring individual meteor-
ological elements (M-54-1, AI~29, M-63M-1, M-49, IVO--1, RDV-3). Informa-
tion is given on the instailation, operation, technical servicing and
very simple repair of remot~ meteoro~ogical instruments. The book is in-
tended as an academic aid for students at hydrometeorological technical
schools. Tt can be us~ful to specialists concerned with the servicing
and operation of ineteorological instruments.

METEOROLOGICAL AND ACOUSTIC EFFECTS FROM ARTIFICIAL HEATING OF TIiE

~Text] Currgntly to stimulate cert,ain mateorological phenomena artificial -
heating of small volumes of the earth's atmosphere is used [1]. Several
methods are based on heating of air during combustion of -chemical fuel.
Fox example, the unit "Meteotron" consists of gas burners arranged on the
earth�s surface [2~. Another device uses streams of hot gases emerging
f~ om jat angine nozzles [1~. Solar energy is also used for heating; a
section of the earth's surface is covered with good light absorb~rs and
- space heating is implemented with the release r~f absorbing aerosols into
the atmosphereo
Tn this respect the use of electromagnetic radiation of the optic and
especially the radio range for heating the troposphere is of undoubted =
- interest. This radiation is noticeably absorbed by the atraosphere. It
is reson,ance with well-pronounced bands of strong absorption saparated -
by windows oi transpa.rency [3]. The achievements of high-power electronics
_ in the problen, of superhigh frequency wave ger~ ration open up an effective
method of axtificial hea,ting of the tropopshere th~,t is significantly
superior in ita potentialities to all the listed methods, In fact~ milli-
meter range radio waves, especially ciose to the oxygen absorption lines at
wave 5 mm make it possible to heat the troposphere in the space of the
~ antenria projector zone. The bas9 area of the vertical air column to be
. heated is regulated by the number and a~erture of the antenrias, and its
_ length--by the frequency sglection; it can be altered in llmits from a
hundred meters to several kilometers. One can essentially create any
aha.pe of volume to be heatedo ~'he temperature gradients in the heated '
_ area generate convective movements of the air ma,sses, ioe.~ affect the
= meteorological processes in the atmosphere.
An important and new qua,lity of volumetric electromagnetic heating is its
low time lag, i.e., the possibility of rapid cha.nges in the absorbed power

magnetic wavee is accompanied by inatantaneous heat release that laads to

' the purpoaes of interpolation between referpnce observations at stations.
In turn, the speedy analysis of CSP data makea possible a sound selection
of points for observation at stations and the density of such observa-
tions. The close interrelationship and interdependence of surface recon-
- naissance observations and observations at stations are obvious.
Gravimetric investigations. Successes in r,~e development of the theory of
gravity measurement on a moving base and the designing of automated on-
. l~oard gravimetric apparatus are now making it possible to c~rry out con-
tinuous measurements of gravity aboard research vessels with an accuracy
to fl mgal if there ia :.orreaponding navigational support. However, as a
re~ult of the distance of the studied objecta from the observation sur-
face there is a marked decrease in the resolution.of on-board gravimetsic
measurements. The gravitational fnfluence of the discontinuity (two-dimen-
sional problem) can be esr_imated u~ing the formula [2]
- - - ~ ~ ~ _ .
~g = 2rrfQe i ~Z~_zl~~ (3)
_ ~here f is the gravitational conatant, CT is the difference in densities
- at the discontinuity, h is the mean depth of the discontinuity, z2 and zl
are the maximum and minimum depths to the discontinuity~ e is the "period"
of the curve.
For example. with a water depth ~of 4000 m the gravitational influence ex-
erted on tt~e ocean surface by uncon~olidated sedimentary deposits with a
density 1.E~-1.7 g/cm3 and a thickness of 500 m, lying on rocks of the
acoustic basement with a density 2.6-2.7 g/cm3, with transverse dimen-
sions 5 lan ("period" - 10 km), will be less than 4 mgal. At a depth of
2000 m from the ocean surface the gravitational influence of thia atruc-
ture increases to 12 mgal, that is, can be reliably registered by modern
sea gravimeters. If the measurements are made at a depth of 3~00 m, that
is, at a distance of 500 m from the ocean floor, the influence of the above-
mentioned structure attains 30 mgal. The approach of the disc~ntin.uity to
the observation level seemingly makes it possible to "focus" the influence
of the discontinuity, to achieve a clearer and aharper manifestation of =
the effect of this discontinuity in the observed field. For this purpose
- it is possfble to carry out analytical continuation of the anomalous field
_ to soMe horizontal plane situated between the observation plane and the
, discontinuity responsible for the pre~ence of the investigated gravita-
tional anomalies. However, in the analytical continuation of anomalous
_ fields into the lower half-space there inevitably wi11 be errors which with
_ the low accuracy of sea measurements of the anomalbus gravitational field
can be extremely significant. Observation of the anomalous gravitational -
field at different levels makes it possible not only Co obtain a sharper
manifeatation of the influence of different anomalous sources in the ob-
- served fields, but also to obtain data on the distribution of the anomalous -
_ r~ravitational field in space.

In a quantitative interpretation a knowledge of the nature of the distribu-
tion of anomalous fields in apace considerably increases the reliability
of the interpreTation resulte [2, 3].
In the Soviet Union specialists have developed a damped float apparatus for `
measuring gravity at different depths from the ocean level (Nemtsov, 1977).
The tests indicated that the accuracy of ineasurements with the float appar-
atus is several times greater than the accuracy of on-board measurements ~
of gravity with moder~x sea gravimeters due to a marlced decrease in the in-
fluence of the disturbing accelerationa of w~ves within the damped float
apparatus, submerged to a depth of 30-50 m.
Magnetometric investigations. Despite the fact that the error for modern r
proton and quantum magnetometers does not exceed f(1-2) gamma, the accuracy
of magnetic surveys in the ocean usually does not exceed t(10-20) gammas. -
This is attributable for the most part to the fact that with low speeds of
towing of magnetometers (10-30 km/hour) it is impossible to filter out the -
diurnal variations from thE anomalous field due to the fact that their ~
- spectra overlap [6]. A high survey aceuracy can be attained by the place-
ment of buoy variation stations or by simultaneously measuring the total ~
~ magnetic field and the gradient using a magnetometer - gradient meter. The
intensity of the magnetic anomalies in the case of observations near the -
ocean floor increases more sharply than in the case of gravitational anom-
alies [1). The strengths of the anomalous magnetic field at different
levels obtained in this case make it possible to obtain the vertical deriv-
ative of the anomalous magnetic field. The use of the higher derivatives
of the anomalous magnetic field is important both for localizing individ- -
- ual anowalies and for determining the par~metera of the sources of anomal- -
= ies .
Thermal investigations are possible only in the case of observations at
- stationo. Under conditions when observations at stations are used for many-
- sided geophysical investigations, the carrying out of such investigations _
~an no longer be regardeu as interference in the carrying out of the main
types of work. ,
In our opinion, the successful further use of thermal observations will
= require measurements of te~peratures in the water layer near the bottom -
and temperatures in the ground at several levels.
A determination of heat flow alone is inadequate for study of the heat i
- field in the section. With the availability of data on the thickness of
- ~edimentary deposits and relief of the acoustic ba~ement data on temper-
- ature in the layer ad~acent to the sediments can be scaled downward into
the region of basement rocks and this will make it possible to study the
structure of the heat field in its relationship to deep stru..ture. Since
the temperature regime of the bottom deposits is essentially dependent
on water filtering processes in this layer, the problem arises of eval-
� uating the intensity of filtration processes as a component part of

thermal investigations at stations. In such a formul.ation thermal measure-
ments are conside~ably complicated and require the development of new meth-
oda and special apparatus. The combination of reeonnaissance investigatioria -
and observations at atations forma a geophysical complex of an operational
character in which it is.already possible to note a definite hierarchy: re-
connaissance investigations have a high productivity, but yield information
in a reduced volume. In this sense the eollected volume of information can
be regarded as adequate for investigations of the reconnaissance type, on
the basis o~ which the points for the stations must be selected. In this -
case observations at stations will represent the second stage in multi-
sided geophysical investigations. ~
Proceeding on the basis of the considerations presented above, it can be
stated with assurance that:
1) the idea that there is an identity in the rate of carrying out recon- _
naissance geophysical investigations and the productivity of geophysical
investigations as a whole cannot be considered correct;
2) there must be a new approach to the problem of many-eided geophysical
investigations in the world ocean in which obaervatiens at atations be-
come an indiapensable part of the full geophyaical compZe:t;
3) the combination of reconnaissance (route) observations and observations
- at atations makes possible a conaiderable increase in the information con-
tent of geophysical investigations and an increas,e in the reliability of
the geological interpretation of geophysiaal data as a whole;
4) the planning and carrying out of geophysical inveatigations in the
ocean must be carried out with adherence to stages: reconnaissance, point ~
(at stationa), polygon;.
_ S) serious attention must be devoted to the development of an instrument -
base for carrying out geophysical investigations us~ng the entire water _
- layer and deep-water bottom observations.

[Text] Annotation. This co 1lection of articles deals with different prob-
lems involved in the prediction of fissured collectors under different
geological conditions. The authors discuss the criteria for evaluating the
influence of post-sedimentati.on processes on the formation of porosity in
calcareous rocks and the patterns of distribution of the collectors (in
the example of Ciscaucasia). The collection also contains data on the role
of dis~unctive dislocations in the formation of calcareous collectors (in
, the example of the Baltic area and the Vuktyl'skoye deposit) and the rela-
tionships among the collector properties of the latter and the cyclicity
of sedimentation. Also examined are the problems relating to the modeling
of a fissured collector, terminology and classification. The book is in-
- tended for specialists engaged in investigations and prediction of calcar-
eous (fissured) petroleum and gas collectors.

[Text] Annotation. The authors of these papers examine the results of
search for the precursors of strong earthquakes, employing an electronic
computer for investigation of various kinds of seismological data (earth-
quake catalogues, bulletins from the network of seismic stations). The
~ articles describe the results of application of a number of statistical
and heuristic algorithms to the probl~ms involved in detecting the loca-
tions of possible strong earthquakes, migration of seismic foci and de- -
termining the mechanism of earthquakes. This includes theoretical inves-
tigations of some direct and invers,e problems in sei~mology: stability ~
of the inverse problem in geometrical seismics, asymptutic mett:~ods in the -
theory of characteristic oscillations of the earth and wave propagation
in stratified porous media. New modifications of spectral analysis are
proposed and investigated. A method for the practical interpretation of
surface waves is dascribed. Plew approaches are found for the designing of -
long-period digital registty apparatus and calibration of earthquakes on -
the basis of long-period records. This particular collection of papers is
of interest for a broad range of specialists in the field.of global and
regional geophystcs, general and shot seismology and seismic prospecting.

VARIATIONS IN ACTIVITY OF WEAK CRUSTAL EARTHQUAKES WITH DIFFERENT c
- FOCAL DEPTHS

[Article by Yu. M. Teytel'baum and V~ S. Ponomarev, Institute of Physics -
_ of the Earth, submitted for publication 26 April 1979]
- Abstract: On the basis of materials on the
seismicity of the Garm region in Tadzhik
SSR the authors make a detailed study of
the temporal changes in the activity of
weak (K~j 7) crustal earthquakes with dif-
" ferent focal depths. It was found that
_ the variation in temporal changes is sub-
- stantially different in different layers.
Near-surface earthquakes, constituting
about 85~ of the total number of earth-
quakea, determine the differences of re-
= gime in individual parts of the region.
The regime of relatively deep earthquakes
(deeper than 10 km) is uniform over the
entire area of the region. The temporal
changes in activity of deeper earthquakes
reveal a close correlation with the oc-
currence of strong earthquakes (K ~ 13-14).
It is manifested in brief increases in
the activity level over the entire area of
the region 1 1/2 years before the appear- ~
- ance of a strong earthquake. Prolonged ten-
= dencies in change in activity level for ,
- deeper earthquakes can be used for long-term
evaluations of che total change in seismic
danger over the area of the region.

observations in Garm region from 1955 through 1976. The location of
the seiamic stations is shown in Fig. 1. The earthquake coordinates were

determined with an accuracy of the classes A(fl-2 km), B(f2-5 km) and
C(t5-10 km). Tfie accuracy in determining coordinates worsene with in-
creasing distance from the network of seiamic stationa [I]. Therefore, -
the principal investigations were carried out over an area of about 104
km2. which in Fig. l,a has been defined as the area Sp. In the over-
whelming tna,jority of cases the coordinatee in thia area were determined
with the accuracy of clasaea A and B. The energy classification of
earthquakes was determined using the T. G. Rautian acale [1]. In this
inveetigation we used earthqualces with K 7 7. They are registered repre-
. sentatively over the entire area of the region.
- The position of the epicenters of the most significant earthquakes occurr-
- ing in the region during the observation period (K = 13-14) is noted in
Fig. l,a. Here, on the basis of data from Leonov [2], we have also shown
the position of the pleistoseist region of the Khaitskoye earthquake of _
- 1949. ~
- In the Garm region it was possible to define three regions differing sub- -
stantially with respect to seismic regime, regions of dynamic coherence _
RDC [3]. In Fig. la they are designated by Rotnan numerals. The principal
differences in the seiamic regime include the different level of seiemic
activity and the nature of the prolonged trends in change of activity. The
regions coincide with the most significant inhomogeneities in the geo-
logical structure of the region: region I coincides with the structures
. of the Southwestern Tien Shan, region II with structures of Petr I
Range, region III with structures of the Darvaz-Karakul'skiy fault
Zone. These geological structures differ with respect to the gradients -
of vertical movemente [4]. In this study the examination of seismolog-
ical data is made for the SP area as a whole and separately for regions
of dynamic coherence.
Spatia]. Structure of Seismically Active Volumes
The distribution of the relative number of earthquakes by depth is illus-
- trated in Fig. 2. The data in the histograms are given in percent of the
total number of earthquakes during the period from 1955 through 1976. As
- the gradation of depth of hypocenters we used an interval of 5 km. The
_ mean position of the seismic stations 1350 m above sea level was
used as the zero level surface.
Some idea concerning the volumetric distribution of weak earthquakes is
given by the maps and sections of the density field of weak earthquakes
- (Figures 1 and 3). By the density n of weak earthquakes is meant the -
number of weak earthquakes n of the energy classes K= 7-12, nortaalized
- in area and time. The number of epicenters for 1955-1970 in the averag-
ing areas was calculated for each layer for constructing the density
maps. The areas used measured 6' x 6' (about 100 km2). They were laid out
with an interval of half the linear dimension of the area. The mean
annual values n of the numbers of earthquakes in the averaging areas were

assigned ro the centers of the areas. The dimensionality of the n val- -
- ues adopted in this study was (100 km2�year)'1. In constructing the
density isolines the assumption wae made that there is a linear change =
in the n values from area to area. Density maps were constructed for
the first three 10-km layers. Earthquakes with foci deeper than 30 km
are indicated by their epicenters in Fig. 1. Sections, examples of
which are given in Fig. 3, were obtained using the density maps. They
reflect the distribution of weak earthquakes in meridional and latitud- -
inal zones with a width of 6'. The n values were assigned to the middlea
of 10-km layera with 5-km intervals. The axial lines of the sections are
indicated in Fig. l.
The cited materials show that the foci of weak earthquakes for the most
part (85%) are concentrated in the upper 10-km layer of the earth's
crust. With an increase in depth their number decreases sharply and deep-
er than 35 km only individual earthquake foci are registered.
The density field in the surface layer has a complex structure. With an
increase in focal depth the field structure becomes simpler and the .
foci of the deepest earthquakes are concentrated in the central part
of the region. On the quantitative side the decrease in the number of -
earthquakes deeper than 10 km is virtually identical in all three RDC,
- despite the difference in their geological structure and in the type of
- seismic regime. Appreciable differences in the distributions are noted
only in the upper 10-km layer.
Table 1 gives the values of the angular coefficient of the graph of fre-
quEncy of recurrence y, computed using data ~or 1955-1976. The table
- ahows that the Y values experience considerable fluctuations both ver-
tically and horizontally. However, the cited data do not exhibit any
significant patXern in the changes in values with an increase in depth.
Table 2 gives data on the change (with depth) of the mean values of the
coefficient of grouping of earthquakes xb, determined for the "north"
- (RDC I) and "south" (RDC II and III) areas of the region. The method for
determining was described'in detail in [5]. The cited table shows
, that the grouping of earthquakes in the "north" of the r~gion virtually
does not change with depth: the values here are close to 0.1. In the
"south" of the region the degree of grouping is relatively great in the
upper layers (x~ = 0.25) and with an increase in depth decreases, tend- _
ing to the value 0.1. In [5] th~ Xa coefficient is regarded as a charac-
_ teristic of properties of the medium. From this point of view the observ-
ed effect can be attributed to the fact that the high values of the
grouping coefficient in the "south" characterize rocks of the sedimentary
- cover of the Tadzhik depression, whose thickness attains 10-13 km. In the
"north" of the same region, where the rocks of the c~ystalline basement
emerge at the surface, the values are identical in the entire depth
- range. _

Changes in Activity of Weak Earthquakes With Time
= A study of temporal variations of the activity of weak earthquakes was made
using time series of the annual sums of earthquakes with K> 7. The sampling
of earthquakes for their ~onatruction was carried out over the area of the
region (SF) and over rhe areas of regions of dynamic coherence. Table 3
- gives the cross-corre].ation coefficients computed in a paired comparison
of time series obtained separately for a group of earthquakes with focal
depths 0-5, 6-10, 11-15, 16-20, 21-25 and more than 25 km. The time aeries
were obtained using data �or the period from 1955 through 1976. Correlation

_ Tuble 3 ehows that the temporal changea in the activity of weak earth-
quakea in the layer 0-5 km are uncorrelated with activity variations in
the deeper layers. The cross-correlation coefficients in layers deeper '
than 10 km are poaitive and conaiderably different from zero, that is,
the changea in seismicity in these layers have a similarity. The tempora~
variation of changes in the layer 6-10 km are uncorrelated with changes
- in the layer 0-5 km and are partially correlated with changes in the 3eep-
er layers. Accordingly, thereafter we compared the behavior of the three
principal sets of crustal earthquakes: surface (0-5 ktn), intermediate (6-
10 km) and relatively deep (deeper than 10 km). The time series of annual
sums with such a subdivision are given in Fig. 4. The annual sums of
earthquakes are shown on the graphs with a three-month interval.
Figure 4 shows that in the changes of each of the time series there is a
syatematic component or long-term trend. Prolonged trends are expressed
differently in different layers: whereas the activity of surface earth-
quakes successively decreased up to 1975, the general decrease in the ac-
tivity of intermediate earthquakes ended much earlier by 1961, and for
relatively deep earthquakes by 1960. Later, fer the two deeper layers
there was a tendency to an increase in activity, so that in the second
half of the observation period the direction of the long-term changes
in the layer 0-5 l~ was opposite the direction in the deeper layers.
- The time series of annual sums of earthquakes with K> 7, relating to dif-
ferent RDC, are given in Fig. 5(surface and intermediate earthquakes)
_ and Fig. 6(relatively deep earthquakes). The cross-correlation coefficients
for the mentioned time series are given in Table 4. Coefficients consider-
ably different from zero with a confidence level P a 0.9 are underlined. -
Different samples are denoted in the following way: Roman numerals are -
employed in designating the regions I, II, III, the superscripts denote
the depth of the layer. For example, I1 is a sampl~ of earthquakes from
- RDC I with foci in the interval 0-5 km, II3 is a sample of earthquakes from
RDC II with foci deeper than 10 km, etc.
Using the data from Table 4, it is poss~ble to compute the mean correlation
coefficients r between the tiffie series relating to different depths, but
- within the limits of one RDC (vertically), and at one depth~but in dif-
ferent RDC (horizontally). Their values are: vertically - r= 0.25 (RDC
I), rII = 0.04 (RDC II), rIII = Q.05 (RDC III), horizontally 0.14
(0-5 km), r= 0.22 (6-10 km), rj = 0.61 (deeper than 10 km).
The cited data show that the nature of the changes in the activity of weak
earthquakes in the case of a layer-by-later examination in each RDC is dif-
ferent. Ariy similarity in changes in the layer 0-5 in different RDC is also ,
lacking. However, this similarity is manifested deeper than 5 km and be-
_ comes significant at a depth greater than 10 km.
It can be seen fram the figures, in which the time series are rep~esented,
that the values of the cross-correlation coefficients are dependent to a
- considerable degree on t~e long-term trends observable in these series.

It is therefore of interest to examine the cross-correlatior. coefficients
of the time series using these same samples, but with the exclusion of
- long-term trends.
In order to eaclude the trends the time series during the period from 1961
through 1976 were approximated by a atraight line obtained by the least
squares method. Henceforth in computing the cross-correlation coefficients
we took into account only the deviations of the individual values of each
series from the approximating straight line. The values of the cross-cor-
relation coefficients of the "short-period" oscillations obtained in this
way are given in Table 5, wh ich was prepared the same as Table 4.
The mean values of the correlation coefficients obtained from these data
= have the followin values: vertically rI =-0.21, rII = 0.34, rIII = 0.16,
horizontally 0.18, r= 0.36, r3 = 0.39. The relatively high value
of the coefficient r~I = 0.34 is attributable, as can be seen from Table
5, exclusively to the high correlation coefficient between layers 1 and
2 in RDC II (r = 0.58). Such a high value can be attributed to the influ-
ence of earthquakes with K= 13-14 arising in thi5 part of the region
_ (their aftershocks and the seismic calms preceding them). In general, how-
~ ever, the cited data also indicate that with depth the regime of weak
earthquakes becomes more uniform, although this phenomenon is not express-
ed so clearly as ~ahen Iong-term trends are taken into account.
The totality of the examined data in general leads to the conclusion tt,at
the differen~es in the regions of dynamic coherence with respect to the -
regime of change in the activity of weak earthquakes with time for the
most part are fixed by the seismicity of the upper part of the earth's
crust. With an increase in depth the differences in regime become less
conspicuous, but in the layer deeper than 10 km the regime of weak earth-
quakes is virtually identical over the entire area of the region.
Correlation Between Strong Earthquakes and Variations in the Activity of
- Weak Earthquakes
- In the Garm region no earthquakes whose energy exceed~d 1014 J occ:urr~d
during the observation period. Therefore as strong earthquakes we arbi-
- trarily used those with K= 13-14. The position of their epicenters is
indicated in Fig. l,a. In Figures 4-6 the sequence numbers of the epicen-
ters correspond to the arrows~ which indicate the moments of occurrence
of these earthquakes.
The correlation between short-period variations of ac~.ivity and strong
earthquakes was determined on the basis of abservatiorial data for 1961-
1976, that is, using that part of the time serie~ ?.n which long-term -
trends in all the samples with some approximation can be considered linear.
The variations of each curve relative to the straight line approximating
it were compared with the moments of occurrence of strong earthquakes. -

The correlation coefficient of the qualitative criteria [6] is determined
by the expression
- Q (~8) (a~) - -
~ (AB) (a~)+(A~) (aB) ~
wE~?ere the following are uaed as qualitative criteria: A is the particular -
value of the time series, not less than th~ moving average, oL is the par-
ticular value of the series, less than the moving average, B is the pres- -
ence of an eazthquake with K= 13-14 in a one-year time period, ~ is the
absence of such. The time series ended with an interval uf three months
and the number of groups of criteria participating in the computation of Q =
was reckoned. The computed values were used in ascertaining the Q(2) func-
tions, cited in Fig. 7. They have the sense of cross-co~ elation functions
[7], where one of the functions is a time series reflecting the change in
activity of weak earthquak~s, whereas the other correaponds to the momenta
_ of occurrence of stron~ earthquakes. The argument of the function t= 0~
f0.5, fl...is the lag time. Since the correlation between the preliminary
values of the activity variations with the subsequent occurrence of strong
earthquakes is of the greatest interest, the series of positive delay time -
values was selected long (up to +2.5 years). Figure 7 showa that the cor- -
relation of earthquakes K= 13-14 with changes in the activity of weak
~ earthquakes is expressed differently at different depths. On the whole,
over the area of the region in the two upper layers there is a significant
positive correlation (Q about +0.7 or more) in the region of negative time -
delay values, that is, with the aftereffects of strong earthquakes. The
seismic activity excited by these earthquakes is localized in the upper
_ two layers, as is indicated by the low value of the correlati~n coef- ~
ficients (Q =+0.2), computed for the layer deeper than 10 km in the re-
- gion of negative delay time values. However, seismicity in the upper two
layers is weak and reacts at different times to the preparation of large
. earthquakes, whereas in the lower layer there is a strong positive correl-
ation (Q =+0.8). This indicates that 1-2 years before the appearance of
ma~or earthquakes the activity in the layer deeper than 10 km increases
considerably, which is qualitatively conspicuous also in Figures 4, 6.
As can be seen from Fig. 7, this type of precursor activation is clearly _
manife~ted almost simultaneously in all three sectors of the region. Fig-
~ ure 7 alse shows that the maximum Q values are attained in the layer 0-10
~ km with lesser 'G values than in the deeper layers. The aftereffect of
earthquakes with K= 13-14 has a local character and exerts a brief effect -
on the form of the time series. It is natural to assume that both the area _
and the duration of the effect should increase with an increase in the -
energy of large earthquakes. Thus, the alr.eady noted prolonged tendency to
a dropoff in seismic activity, evidently, is attributable to the afteref-
fECr of the Khaitskoye earthquake of 1949 (M = 7.4). This is supported by
- the fact that the tendency to a decrease in the activity of surface earth-
- quakes lessens wi.th increasing distance from the focal region of the Khait-
- skoye earthquake: in RDC I in 22 years it decreased by a factor of 10, in
RDC II by a factor of 2, in RDC III, at more 50 km from the epicenter
- the influence of the Khaitskoye earthquake cannot be traced on the basis

km, here both at the beginning of the obaervation period and iater the gc-
tivity changea were synchronous and virtually 13entical in value in all
three RDC (Fig. 6), from which it can be assumed that ti:ese changes were -
caused by ot~er factors. In genera~, the form of the long-term tendencies -
in change in activity of weak earthquakes during the couree of the observ-
~ aticn period seemingly wae determined by the interaction of two factore:
the aftereffect of the Khaitskoye earthquaker manifested primarily in the
upper layer of the earth's crust, and the influence of some mnre general
- factar, be3ng manifested primarily in the activity changes of deeper earth- _
quakea. As a result, the course of the temporal changes in different layers
was different up to and including oppositely directed changes.
Discussion of Results
The results show that the overwhelming ma~ority of the foci of weak earth-
quakes in the Garm region are concentrated in the upper layer of the earth's ~ -
crust with a thickness of about 10 km. Therefore, the pattern of manifesta-
tions of weak seismicity, e~canined in the entire group without separation
by depth, for the most part reflects processes transpiring in the upper
layer of the earth's crust. Moreover, the behavior of seiamicity vertic-
ally differs extremely significantly: in the uppex layer the c}iangea in
the activity of weak earthquakes have a similarity only within the limits _
af one RDC [3], whereas in the layer deeper than 10 km the simi',arity is _
manifested over the entire area of the region. It is obvious fro~ this _
that more 1QCa1 factors exert an influence on changes in activity near the
surface. Evidently, this phenomenon reflects the usually observed complic-
ation of geological structure of the earth's crust from the deep layers to
. the surface (for example, see [8]). It is not impossible that here there
is reflection of the course of those processes which form the indicated
complication of structure.
The idea of a difference In the conditions for formation of geological
structures vertically has been examined, for example, in [9~. According
to this study, the differences are determined by the dependence of the
mechanical properties of the rocks on temperature and pressure; with an
increase in the latter the capacity of rocks to flow increases. Therefore,
first, the rocks near the surface are more brittle, and second, the life- _
_ time of structural inhomogeneities decreases with depth. In agreement with
such ideas it can be assumed that the marked incr~ase in the activity of -
_ weak earthquakes in the layer 0-10 km is associated with increased brittle-
ness of the rocks in this layer, whereas the greater uniformity of the re-
- gime of earthquakes deeper than 10 km reflects the greater uniformity
of this structure of deep layers of the earth's crust. Since the relaxation
time af stresses at relatively great depths is relatively small, the struc-
ture of the medium here is morP uniform and the changes in the level of ac-
tivity of weak earthquakes at this depth mare closely follow the changes -
in the level of tectonic stresses than the changes in the activity of -
eaxthquakes in the less deep la}rers. _

- Disturbances in the field of activity of weak earthquakes, caused, for ex-
ample, by the appearance of major earthquakes, are expressed more intensive-
ly in the near-surface layer and last far longer. This, in particular, can
explain the different direction of changes in the activity level of weak =
earthquakes in the layer 0-5 km and in the deeper layers, caused by the
aftereffect of the Khaitskoye earthquake (particularly well expressed in _
RDC I). This sort of local effects, strongly and persistently expressed
in the upper layer of the earth's crust, mask the general changes trans-
piring at great deptit. However, the latter, in all probability, ref~pct ~
more important, more general changes in the level of tectonic stresses in
the region, which in the last aualysis also determine the appearance of
- ma~or earthquakes. For example, it follows from Fig. 6 that bri~f increases ~
in activity in the layer deeper than 10 km aftQr approximately 1 1/2 years !
resulted in the appearance of the strongeat earthquakes in the region. A '
pro~enged increase in the activity level, beginning in the early 1960's,
was accompanied at the end of the obaerva~tion period by a series of earth-
quakes wit~ K= 13 which followed one another with unusual frequency. Five .
such earthquakes occurred in the region (in the area Sp) dur3ng the period _
1975 through 1978, and in the immediatie neighborhood of the region (first
tens of kilometers) two. Such an intense seismicity was not observed in _
- the region after the Khaitskoye earthquake of 1949 and its afterahocks. -
It was demonstrated in [10] that active and inactive periods alternate in
_ the life of the main seismic zones of the world. In particular, in the ;
Alps seismic zone (where the Garm region is situated) seismic activity -
changea almor~t simultaneously through the entire znne. It is not impos- ;
sible that the prolonged changes in the activity level of relatively deep ;
earthquakes which we examined characterize not only the seismic conditions
in the Garm region, but also are related to the development of strong

earthquakes over a far greater area. Thus, in the near-lying part of the
Central Asian seismic region a series of ma~or earthquakes occurred in re-
cent years, among them the Markansuyskoye earthquake of 1974, the earth-
quakea at Gazli in 1976, the Isfarinskoye earthquake of 1977, the earth- -
quake of 1978 in the Alayekaya valley. Another, earlier period of activa-
tion of large earthquakes in this part of Central Asia, lasting about 15
years from 1934 to 1949, was represented by such earthquakes as the Argan-
kul'skiye earthquakes of 1934-1935, the Garmskoye earthquake of 1941, the
- Fayzabadskoye earthquake of 1943 and the Khaitskoys earthquake of 1949.
Earth~uakes of the same intensity in the intervals between these two per-
iods, and also long before the period 1934-1949, did not occur here. It
is noted in [10] that the "existence of active and inactive periods in the
main seismic zones of the world is one of the fundamental problems in
long-range forecasting of seismic activity." The cited data show that in -
the considered part of the Central Asian region there is a distinct alter-
nation of active and inactive periods. In the light of what has been said, .
prolonged changes in the activity level of ~eak, relatively deep earth- ~
quakes appear promising as an indicator by means of which it is possible to
_ predict the alternatiun of such periods, and what is especially important,
to predict an increase in seismic danger in the region prior to the develop-
- ment of major earthquakes. _
To what extent are the patterns ncted in the behavior of relatively deep ~
earthquakes manifested in the total group of earthquakes? Figure 8 gives
an answer to this question. This figure is a graph of h-- the temporal
changes in the mean annual values of focal depths in the region and the con-
- fidence intervals of the h values with a confidence level P= 0.95. In com-
puting the h values all the hypocenters for a year interval of summation
in each 5-km layer (0-S, 6-10,.,.,20-25 km) were reduced to the middle of
the corresponding layer; earthquake foci deeper than 25 km were related to
a depth of 27.5 km.
Figure 8 shows that the mean annual focal depth decreases from 1955 to 1959
_ from h r 6.5 to h N 4.5 km. Then there is a change in the direction of the
trend, which retains its sign virtually zo the end of the observation per-
iod. It is evident that at the beginning of the observation period the form -
of the time series was greatly influenced by the high activity of relative-
ly deep weak earthquakes, associated with tfie Khaitskoye earthquake, and `
rapidly decreasing after it. After 1959 in the entire group of earthquakes .
it became possible to trace a tendency tu a systematic increase in h.
Against a long-term increase in mean focal depth one could see brief "plung- -
ings" of the hypocenters, after which earthquakes with K= 13-14 developed.
, Such an effect was observed before some earthquakes with M r 5 in Central
California [llJ. In order to evaluate the correlation of earthquakes with
K~ 13-14 and brief oscillations of h, the already described method was
used in computing the function Q('G) (for the periocl 1959-1976). It was
_ found that the effect of an increase in the mean focal depth of weak earth-
_ quakes gives a maximum value Q=+0.93 1 1/2 years before the appearance
� of a strong event. Thus, the information which is contained in variations

_ of inean focal depth is essentially the same as in variations of change in
activity of only relatively deep earthquakes.
We also note the following. As indicated by the cited data, ea~h brief ac-
tive period begina with a marked activation in the relatively deep layers "
of the earth's crust and affects the entire seiamically active area. Then
activation begins in layers with a lesser depth. This, in particular, is
evidence that if extraterrestrial factors also exert an influence on the
change in the level of tectonic stresses, their influence nevertheless
is first reflected in the earth's deep layers and the activity of the
earthquakes is propagated from the deep layers to the surface, as if it
was caused by endogenous factors. The process of activation of earthquakes
in the surface layer seems to be sort of secondary relative to variations
of activity at a greater d~pth. -
In general, it follows from the content of this study that the appearance
of bri.ef maxima in the number of relatively deep earthquakes or brief
"plungings" in the mean depth of hypocenters can be used in predicting
earthquakes with K~ 13-14 for about 1 1/2 years in advance; the form of -
the long-term trends in the change of these characteristics can be uszd
in long-term evaluations of seismic danger.

NEW SYSTEM OF TECTONZC CONSTRUCTIONS FaR THE TERRITORY OF SIBERIA
Moscow VESTNIK AKADEMII NAUK SSSR in Russian No 10, 1979 pp 84-87
[Article by Professor K. V. Bogolepov]
[Text] On the initiative of scientists of the Institute of Geology and
Geophysics Siberian Departmetit USSR Academy of Sciences, supported by
the administration of the Ministries of Geology USSR and RSFSR, in 1978
ma~or interdepartmental work began on compilation of the ATLAS TEKTON-
ICHESKIRH KART I OPORNYKH PROFILEY SIBIRI (At1as of Tectonic Maps and
Reference Profiles of Siberia). Participating in this work are geologists
and specialists in tectonics and geophysics of institutes of the Siberian
Department USSR Academy of Sciences, branch scientific research insti-
tutes of the USSR Geology Minisr_ry and Siberian territorial geological ad-
ministrations and trusts of the RSFSR Geology Ministry.
- In working up the program and method for compiling the atlas the initiators
- of this work proceeded on the assumption that the long-range support of
- the national economy of the USSR with raw material and mineral resources,
including power resources, is dependent to a considerable degree on the
reserves contained in the territory of Siberia. Its territory, occupying
more than 10 million square kilometers, that is, approximately ~a5% of the
area of the entire country, is exceed~ngly diversif ied ~n geological struc-
ture and compoeition of already known raw material deposits. The scientific
- prediction and detection of new deposits of petroleum and gas, ferrous and
nonferrous metals and c:hemical raw material~, hidden below the earth's sur-
face, require a clear knowl.edge of the present-day structure of the earth's
crust the spatial relationship of the geological bodies making it up,
formed by different rock formations, including those bearing ores.
The era of discovery of new mineral deposits at the surface, even in the
least studied regions of the enormous territory of Siberia, is approach-
ing an end. In order to predict hidden deposits and at the end of the cur-
rent century and at the beginning of the future century to exploit suc-
cessively ever-deeper Y~rr_s of the crust and its power and other raw mat-
erial resources it is necessary to ha~e additional information on the sur-
face geological structure. Approximate qualitative structural ma.ps of deep
layers prepared on the basis of existing tectonic mapping methods also do

- not meet acientific and practical needs. It is necessary to create three-
_ dimensional quantitative models based on spec~.fic data on mineralogical
, composition, structure, geometrical relationships and geological age of
bodies which are discri~ttinated in the form of layers, tectonic lenses,
blocks, complexes, etc., depths, degree of dislocation and metamorphic
transformations. The prototype of such tectonic models, which should
cover the earth's crust as a whole or a part of it to some stipulated
depth, is the constructions employed in practical geological practice
in determining the structure of ore fields and in calculations of the
mineral reserves. In these models the size and properties of bodies are
determined from the vertical coordinate in the same system of ineasure-
- ments and with the same accuracy as from the horizontal coordinate. ~
The creation of quantitative tectonic models, reflecting really eaisting
natural situations, will have far-reaching scientific consequences.
- These models are extremely necessary as a basis for the reconstruction of
geodynamic systems of the geological past, revisinn of global tectonic
hypotheaes, formulation of a general theory of structure of the earth
and its evolution.
The syatem of constructions plauned in work on the atlas is the first such
undertaking in world practice and therefore it requires the formulation
- and solution of a number of exploratory theoretical and practical prob-
lems. Among these a key place should be occupied by the creation and im-
provement of inethods for correlating geological and geophysical criteria
for the discrimination of geological bodies. Among the geological cri-
teria which are established visually and which at present are only predict-
. ed in depth, procee~iing on the basis of structural and historical geology
, data, the most important are mineralogical (rock) composition and the in-
ternal structure of geological bodies. The geophysical criteria, determin--
ed by instrumental remote methods, inelude a complex of interrelated
characteristics density (velocityZ, magnetic susceptability, conduc-
tivity. They are dependent on the above-mentioned geological properties,
but their correlations with the structure and composition of the mineral
masses, found under different natural thermodynamic conditions, have not
_ been determined. It is diff icult to expect that in the years immediately
ahead in compilation of the atlas there will be complete solution of the
problem of detecting and correlating geological boundaries by means of
geophysical methods. However, it is of very great importance for the fur-
ther development of geotectonics, petrology and mineral science, and key
groups of scientists must be directed to its solution.
Thus, the purpose of compil ing the atlas is the creatidn, for the first
time for the territory of Siberia, of a three-dimensional model of the
present-day stru~ture of the earth's crust. The implementation of this
~ ob~ective provides for:
synthesis of present-day data on the mineralogical compoaition, struc-
ture and age of the geological bodies making up the surface Farts of the
earth's crust and on their geophysical parameters;

- systematic knowledge concerning the deep geological structure of the
earth's crust and determination of deep bedding conditions of geological
bodies both discriminated at the surface and hidden below it, by means of
improvement in methods for correlation of structural-mineralogicai and
physical criteria and multisided geological-geophysical modeling;
_ detection of spatial and genetic relationships in the development of
geostructural regions (geosynclinal folded systems, platforms, orogens)
- in the course of individual tectonic epochs, that is, analysis of lateral
series of aimultaneously forning structural elements;
determination of the general patterns of formation and evolution of
the earth's crust in Siberia, its mineralogical composition and structure.
In general form the continental crust is a system of discontinuous shells
(they are conveni~ntly called megacomplexes), of different age, superpos-
ed on one another, corresponding with respect to time of formation to
large planetary or subplanetary tectonic eras: Prekarelian, Karel-
ian, Baykalian, Caledonian, etc. The internal structure of the megacom-
plexes is determined by the combination of geological bodies of the next,
lower rank. In accordance with the eaisting tectonic nomenclature, these
are geosynclinal, protoorogenic (epigeosynclinal), platform (shield) and
deuteroor~genic (including intracontinental rift) complexes. Within the
megacomplexes they replace one another both in the vertical stratigraphic
section and in the lateral directfon. Their regularly constructed, inter-
related vertical and horizontal series reflect the dynamics of formation
of new and transformation of the already continental crust in the course
of a tectonic era. The units of the next ranks, into which the complexes
. are subdivided, are structural stages, substages and the geological for-
mations making them up. The latter serve as the principal indi~ators in
~ determining where the complexes b~long in the classification.
The boundaries of the megacomplexes usttally correspond to the largest
structural "reorganizations," express~ri in deformations (including dis-
" placements and faulting) of the earlier consolidated crust, the formation
of new systems of geosynclinal, platform and deuteroorogenic downwarps,
- the formation of extensive inte?-regional surfaces of structural and strat-
igraphic disconformities. In geosyticlinal folded regions the base of the
sections of the megacomplexes coincides with the bottom of the geosyn-
clinal formations of the corresponding tectonic era, frequently lying in
zones of parting in a crust of the oceanic type, and the top of the sec-
tions with the top of epigeosynciinal (protoorogenic) strata or rocks
associated with them which were formed during the stabilization of oro-
gens prior to deformations, marking the onset of a new tectonic era. But
there are also more complex combinations when geosynclinal formations
within one and the same megacomplex are underlain by rocks belonging to
platform (shield) and deuteroorogenic complexes. There are also cases of
disruFted stratigraphic sequence, when the ancient megacomple~ces or their
component elements, as a result of displacements and shifts along subhor-
, izontal surfaces,lie on younger formations. Also common are structural
_ "spikes" of inegacomplexes associated with "through" identical development

of geosynclinal, p~atform and similar complexea from one tectonic era `
to the next. These different structural relat~r-~ghips are exceedingly
complex, but precisely they predetermine the principal patterns of dis-
tribution of minerals.
_ The work program on the atlas provides for the compilation of 11 maps of
tectonic and geoprysical content, including individual tectonic maps of
megacomplexes: Karelian (including more ancient Archean formations), Bay-
kalian, Caledonian, Early and Late Hercynian, Mesozoic-Paleogene and
- Neogene-Quaternary (most recent tectonics). In addition, specialists
will compile the following: summary tectonic map for the entire system
of inegacomplexes, map of relief of the surface of the folded basement
of platform regions, map of the deep structure of the earth's crust and
_ upper mantle, map of the present-day state of the earth's crust (stresses, -
heat flows, seismicity, recent movements), and also a series of reference
geological-geophysical profiles intersecting the principal geostructural
- regions of Siberia.
~ The compilation of individual maps for each megacomplex will make it pos-
_ sible, making extensive use of the possibilities of geological-geophys- -
ical modeling, to analyze the spatial d.issemination, thickness, depth
and structure of vertical and lateral series of component elemenzs of
megacomplexe~ not only within the limits of their outcropping at the sur- -
- face, but also under a cover of younger platform and geosynclinal fold-
ed formaticns. In this case it is possible to expect the detection of new
- and extremely significant patterns. -
_ The complex of planned studies not only will afford a possibility for solv-
ing a niimber of theoretical problems in geotectonics; it will serve as a
basis for predicting and searching for mineral deposits in structural
stages of the earth's crust in Siberia of different age, including ore de-
posits, whose distribution is governed by geosynclinal prehistory and
repeatedly occurring deuteroorogenesis. -
~
Within the limits of the Western Siberian Platform the carrying out of
these studies will ensure the determination of the limits of occurrence
and volumes of potentially petroleum- and gas-bearing deposits of Paleo-
zflic platforms and orogenic downwarps, undsrlying the Mesozoic cover.
In the territory of the Siberian Platform it will be possible to make a -
more precise determination of the morphology and spatial relationships of
Riphea:~-Paleozoic structural stages and def ine regions which are of the
greatest interest for detecting commQrcial resources of petroleum and gas,
potassium salts, copper-nickel and iron ores, etc. Within the limits of
the folded structures framing present-day platforms, in addition to es-
tablishing the tectonic prerequisites for the formation and distribution
of stratum and stratiform deposits, analysis of the distribution of fold-
ed and disjunctive dislocations and their gosition in depth in different
structural stages will make it possible to ciete-rmine more precisely the

posaibilities of detecting zones and centers of concentration of ore de-
posits both at the surface and in depth.
An important practical problem of the work which has begun, whose imple-
mentation will in large part be dependent on the broad participation of
= production organizations of the USSR and RSFSR Geology Ministriea, is
the compilation, using a unif ied method and with standard legends, of a
- aet of detailed tectonic maps for the territories of activity of geolog-
_ ical administrations. Constituting first compilations for the atlas,
- these maps at the same time must be working maps, systematically being -
supplemented by new factual material and serving territorial geological
administrations and trusts as a permanent basis for detailed metallogen-
etic prediction and the drawing-up of long-term plans for specialized
and geological prospecting studies.
Work on compilation of the atlas is proceeding. At the interdepartmental
working conferences held in October 1977 and May 1978 at Novosibirsk, -
_ the program was adopted, a general draft of the legends and methodolog-
ical recommendations were approved. An editorial board, headed by Acad-
emician A. L. Yanshin was formed, which included leading scientists and
specialists of the Siberian Department USSR Academy of Sciencea and the
= USSR Geology Ministry. Map compilation groups for individual territories
of Siberia were organized. They are Iieaded by leading specialists in the
field of regional tectonics.
In accordance with the prepared calendar plan for work on atlas compila-
tion, it is proposed that the collective monograph TEKTONIKA I EVOLYUTS-
IYA ZEI~IIJOY KORY SIBIRI (Tectonics and Evolution of the Earth's Crust in
- Siberia) be completed in 1983. This work is part of a complex superpro-
gram for e~cploitation and preservation of natural resouices in Siberia,
developed ~t rhe present time by the Presidium Siberian Department USSR
Academy of Sci~~nces with the participation of interested organizations.

- [Text] Annotation. This monograph contains a review of inethods for poten-
tial analysis of the fields of geomagnetic variations and storms together
wir_n a mathematical description of these fields and their dynamics. The
authors set forth a theory of electric field~ and currents in the earth's
quiet plasmosphere and phenomenological models af magnetospheric sub-
stiorms. The monograph describes a new class of geomagnetic b-fields, each
_ of which is a response of the earth's magnetic field to a change in one
of the parameters of the solar wind. Methods for computing three-dimen-
sional systems of electric currents in the geomagnetosphere are given us-
ing surfa~e data and the first results of their use. The book is intended
for geophys-icists, space physicists and students in the corresponding
fields of specialization. _

[TextJ Annotation. This collection of articles continues the publication
of e~aterials related to the problems involved in the methods, technology
and economy of marine geophysical studies on the shelf of arctic and east-
ern seas of the USSR and in individual regions of the world ocean. The
- authors analyze problems relating to the physical geology and interpreta-
tion methods in the geomagnetic and geoelectric stud~ of the bottom aec-
- tion of oceanic and shelf regions. The papers give the results of ~oint
analysis and computer processing of magnetic and gravitational fields of
the northeastern nart of the Siberian platform and also data on study of
variation of the geomagnetic field on the shelf and experimental formula-
tion of electric proepecting work d::~r.2 while the ship is in movement.
Also diecusaed are the problems relat3ng to the methods for carrying out
highly precise aeromagnetic surveys. The principal methodological pro-
cedures for the interpretation of these materials are characterized and �
described. Attention is givan to further investigation of the possibilit- ~
ies of the spectral-spatial method for separation of the anomalous magnetic
field. A number of articles are devoted to the method for marine aeismic
investigations on the shelf and work on the problems involved in their in-
terpretation. Included are materials relating to the snathematical support
~ (for programming purposes) of solution of the problem of constructing a
seismic discontinuity in an inhomogeneous medium and also relating to
individual problems in the processing and interpretation of gravitational
data and explaining the geological reasons for the seismological activity
of individual sectors of the shelf. :
