Title Determining the fields of intensity of seismic waves
Periodical Izv. AN SSSR, Ser. geofiz. 1, 11-25, Jan/Feb 1954
Abstract In the iegion close to the front of the wave the energy of the oscillations
is propa.-ated along rays. Its flow is similar to the vortexless flow of an
incompressible fluid. In connection with this similarity the author formu-
lates the problem of determining the intensity of the seismic waves within a
medium if one is given the hodographs and intensities of the oscillations
(or amplitudes of the displacements) on the surface. The author proposes a
method for solving this problem.

Title : Determining the dependence of the velocities of propagation of elastic
in samples of mineral rocks upon one-sided pressure
Periodical : Izv. AN SSSR, Ser. geofiz. 193-197, May-Jun 1955
Abstract : The authors work out a procedure for determining the dependence of the veloci
of elastic waves upon mechanical stress. The measurements are conducted by
means of the ultrasonic impulse method upon samples of mineral rocks under co
ditions of one-sided pressure. At the same time they determine the static an
dynamic moduluses of elasticity. Certain results of these measurements are
presented. The senior author cites his three earlier works, co-authors:

modeling of seismic waves by ultrasonic impulses. Total of seven references

Title Communications. Seismoacoustic methods for studying the stressed
state of rocks
Periodical Izv. AN SSSR, Ser. geofiz., Nov-Dec 1955, 538-54o
Abstract A report delivered at the 16 March 1955 session of the scientific
council of the Geophysical Institute, on the action of mechanical
stresses on the state and particularly on the elastic properties of
rocks, of interest in connection with the struggle against mine
shocks or bursts as in coal mines. This problem was studied under
the general guidance of the author in the laboratories of modeJ4
Mg
and underground acoustics in the seismic prospecting division of
the Geophysical Institute, especially the problem of mine pressures
(i.e. the stressed state of rocks close to the mining operations.
With the object of testing Academician A. A. Skochinskiy (Institute
of Mining, Acad. Sci. USSR) proposed methods and other proposals,
the Geophysical Institute developed and tested two geophysical (more
precisely, seismoacoustical) methods: 1) the shaft impulse seismic
method based on the disturbance of artificial elastic impulses and

medium; and 2) the shaft acoustic method based on the study of the
natural elastic impulses (noises etc.) arising in a maz3s under the
action of the mine pressures.

ABSTRACT: The study surveys various methods for the investigation of stress
conditions in mountain rocks. Principal attention is directed to the
impulse method and the acoustic method. It is indicated that with an
increase in pressure the modulus of elasticity grows faster than the
density. Therefore, the speed of sound, which is proportional to the
square root of the ratio of the modulus of elasticity and the density,
increases with increasing pressure; more specifically, the speed of
sound is proportional approximately to the one-sixth power of the
Card 1/Z pressure. It is noted, further, that the formation of cracks, at the

inception of failure of mountain rocks, is accompanied by a crackling
noise. The study of the vibrations arising in the rock during failure
is the basis of the acoustic method.
A description of a laboratory set-up for the study of the velocity of
sound in stressed rock samples is offered, also a description of model
tests and observations in mines by means of the seismic impulse
method.
A survey is made of destructive compression tests on rocks, the
apparatus and methodology for the study of the elastic impulses
accompanying their failure, and corresponding observations in mines.

!ABSTRACT: The -D!,ubleia of e layer in cn elastic inedium is considered.
The layer is finite or thin compared the wavelength of
the prevalent wave. The 1-~,yer differs from the surrounding
medium in that the velocity of propa~-aition of elastic waves
in it is higher then in ~Iie surroundiriL medium. It is called
a "high velocity layer" (HVL). The leyer may act as a
Card 1/3 waveguide for the so-c.-Med lonLitudinLl slip waves. The
problem of the HVL was considered by tLe present auth-or in
a previous paper (Ref.12). Results obtained with a three
dimensional model of a thin solid layer in a liquid vvere
used in that paper (Riznicileriko et el, Refs-13-15). The
present paper is a continuation of FtLf- work reported earlier.
A two dimensional model of a stratified solid medium was
used to study the propagation of elastic waves in a jaigh
velocity layer of the kind described above. The waves were

excited by an ultrasonic netnod. Tile digh velocity layer
was made of duralumin (5400 m/sec) and the lower velocity
niedium was of plexi6lass (2300 m/sec). The following
special cases were studied: 1) free thin layer; 2) thin
tligh velocity layer on a semispace, 3) thin high velocity
layer placed under a layer with a lower velocity; 4) thin
high velocity layer in an in-f inite medium wit?l a lower
Velocity; 5) thick high velocity layer in an infinite
medium of lower velocity. Results are given on U-he
velocities of propagation, radiation and absorption
coefficients, dispersion and phase and group velocities.
The velocity of propa6ation of lon,~itudinal waves in a HVL
surrounded by an elastic medium does not differ significant-
ly from the velocity in a free layer. The difference in
velocities is about 2rlc' which is slii~dtly hiLd-)er than the
ex-Derimental error. The radiation coefficient for a
lonE,;itudinsl slip wave in a HVL placed on a semispace with
a lower velocity is equal to the radiation coefficient for
tae HVL -Dlaced under a layer with a lower velocity, but is
Card 2/3 half Thai for a HV-L in an. infinite medium. A com-oarison of
the P121 waves in thin and thick layers of duralumin

showed that the velocity of propagation of a lo-ri6itudinal
slip wave is higher and the frequency lower, in the case of
the thick layer. The difference is of the order of 8%. for
both the velocity &-ad the frequency. The coefficients of
absorption and radiation are auch lower in the case of a
thick HVL.

ABSTRACT: Brief review of Soviet seismological investigations in the
high frequency range of the spectrum, i.e. 10 kc/s and
higher. The term ultra-sound is used in this paper in its
wider sense for designatin8 not only the longitudinal
ultrasonic elastic waves but also other elastic waves,
i.e. transverse waves, surface waves and others, differing
from the waves considered in "classical" seismology only
from the point of view of their higher frequency. Since
ultrasonics are intensively absorbed in rocks, the field
of their application in seismology is limited almost
exclusively to experimental seismology in cases in which
the distance from the source is still so small that the
ultrasonic waves can still be distin&,uished at the metering
point. The author considers the application of ultra-
sonics to the following concrete problems: simulating on
models of seismic wave processes directly related to the
Card 1/2 study of the structure of the Earth by seismic methods;
study of the elastic proloerties of rocks on specimens and

under natural conditions; study of the stuatue of solid
bodies under conditions of increasinE mechanical stresses,
up to breaking stresses,which is :oelated to the study of
processes in the foci of earthquakes and also to a
number of other applied problems as, for instance,
investigation of rock pressures. This article is based
on the text of a paper read by the author at 'the First

data of a given type. including surplus data, to be carried
out wit-nout a preliminary and arbitrary division into groups;

ABSTRACT: An expedition was organised in 1953 to Garinskiy rayofi, -Tadzh
33R; in order to inves-tigate their seismic systems. The
method of investigation and the results obtained are summ-
arised in this work.
To standardise the procedure, each earthquake was repres-
ented mathematice.11y as E. poiat in the five-dimensional
space (F~ 5) . These waTe: x, y, z - the co-ordinates,
t -- time and E - energj of se 4smic activity. Thus, it
was possible to derive a function for each earthquake and
a set of funct-ions gave );he characteristics of a given
seismic system. These were described by: an equation of
seismic a-~~tivity (A,. thne value of energy variation (y)
and the f::-quency Uf ~~ai-thquakes (R).
In orde V 4-0 facill'-,ate !~~ie analysis of data, the diagrams
based on the abcve f-vt- 'LJ_Y'6nGioLLs were plotted.

The frequency graphs were produced for various reg-ionsL.

A mean seismic activity (A) was determined for each
ngion by considering the mean energy Ko ? (Figure
in the formula:
N* = 10 log A+Y(Ko - K)
K
the mean seismic activity for the Garm region (Figure 3a)
was determined as A 7 ~ 5.0 year-1 10-3 ki-3 and
A7 =0.9 for the Stalinabad region. Charts were con-
structed where A was plotted (Figure 4 for Garm and
Stalinabad). Only the weak earthquakes (energy 7-9) were
considered-owing to their high frequency. The strong ones
(energy 10-13) were shown as black circles of various
dimensions.
The frequency distribution of the weak earthquakes was
L;ard3/6 found to be normal. This can be seen in Figure 5 where

On'Investigation of Seismic ;:iys-uems SOV/49-58-9-1/14
curves were drawn for different K (calculated from
E = 10K joules) for the Garm. region. Similar curves for
the Stalinabad region were less accurate, thus giving an
evidence of less frequent earthquakes in that area.
Therefore, a period of observation had to be considered
in relation to frequency 'that an error in calculation
should be avoided. A relation of energy K in a period
of years and the monthly frequency V K was calculated.
Figure 6 ahows this relation for the Garm region, as
observed (1) and calculated (2) with 10016 of accuracy.
The theoretical curTe was obtained from the formula:
R -!- a.N/\FN- 6x N = const',
where a mean square of frequency (N) error. The
value for R was found to be equal about one (e.g. Garm:
R = 1.05 � 0.08 during 1955/1956; Chusal: R = 1.3,
see Figure ?). In order to include the parameter of error,
a diagram was constructed (Figure 8) based on the equation
uard4/6

On Investigation of Seismic Systems SOV/49-58-9-1/141
t = (R/cT)2 (100/SA) 10 Y(K-Ko)
where R = 1-05, Y = 0-43, Ko = 7, A = A?
S - area in km2 . The required frequency can be estimated
from this diagram, e.g. the dotted lines being the para-
meters for the Garm region,, ishow that with 101% of error
and the energy of 7, the period of two years is necessary
to obtain the required frequency. Similarly, for the
weak energy of K = 2 in the Chusal area, the time of
12 hours would be sufficient. On the other hand, for the
earthquake with the ezergy K = 1? (-rn'the 1~haitzkiy,
Rayan "- in 1949) a period of 500 - 1 000 years would be
required. The diagram was calculated for the normal
distribution. Therefore, it cannot be applied in the rare
cases of the frequency distributed in the other form.
In order to find out a relationship between y, A and R
for the energy of K equal up to 12, the observations were
carried out in the area of Peter I Mountain for two years
(Figure 9). The resultant curve of all the three-values
Gard5/6 was found to be very similar to the R cu-rve.

ABSTRACT: At the Institut fizi'Ki Zemli AN SSSR (Institute for the Phy-
sics of 'the Earth, AS USSR) a method was worked out under XIL.
M1. Yepinatlyeva, -which makes it possible to evaluate the
tran5parency of layers. The effect produced by the wave of
a short momentum originating from an arbitrary point o-f the
disperging medium or. the surface is calculated. Ficure 1 shows
a scheme of the discersed wave for three layers, and calcula-
tion of the reflection- and refraction coefficients according
to the scheme shown by figure 2 is carried out. The recurrent
formula (1) for signals coining from an arbitrary point after
reflection and diffraction and arrivin- at an arbitrary point
is written down. The coefficients occurrinE therein are in-
vestigated, and for the latter the general formula (7) is
Card 112 written down. It is found that relative transparency may be

is judged according to the relative intensity of a single re-

the aim of studying the nature of earthqtakos and the conditions of their
Gonosis. The most Beismically-aqtivO zones of the USSR (Garmo, and Stalina-
bad) were chosen as the work aroas. The specific oonditiona of vvrking
and processing the data demanded the development of special systems of ob-

TITLE: On multiply reflected and transmitting waves
PERIODICAL: Akademiya nauk SSSR. Izvestiya. Seriya geofizicheekaya,
no. 12, 1960, 1689 - 1706
TEXT: The present authors report a more detailed account of the
theory developed by Yu.V. Riznichenko (Ref. 2: Dokl. AN SSSR, 126,
nof 4, 1959). The theory was checked experimentally with the aid of
models and the pulse ultrasonic method described by Yu.V, Rizni-
chenko, B.N. Ivakin, and V.R. Bugrov (Ref. 3: Izv. AN SSSR, ser.
geofil., no. 2, 1959). The problem is formulated as follows: Consi-4
der a multilayer medium which consists of a uniform elastic half-
space with thin-layer inclusions, whose elastic properties differ
from those of the main medium. The layers form a plane parallel pe-
riodic sequence with a constant spacing h. The source ofseismic
oscillations S produces short pulses which are then applied to the
free surface OA of the half-space. The seismic waves are observed

at a point A on the surface, or within one of the layers (Pig. la).
Waves emitted by the source are reflected and refracted in the me-
dium, the reflection and transmission coefficients (energy coeffi-
cients) being r and p respectively. If for some reason a fraction q
is absorbed by the medium, then p + q 4- r = 1. The coefficients p,
q and r are in general functions of frequency. The problem consists
in determining the number of all the waves reaching A simultaneous-
ly with the single reflection from the lowes't-lying layerp and the
intensity of all the scattered waves. The calculation is based on
the following considerations: In order to facilitate the discussion
the authors introduce a further (fictitious) medium which lies above
the actual medium and is coterminous with it (Fig. lb). In order to
obtain the true ray patterns the latter figure should be folded
about the line OA. Two assumptions are then made. Firstly, it is
assumed that OA is a thin layer similar to the other layers, and
secondly, it is assumed that the source S emits waves both in the
upward and the downward direction S. It is then shown that under
these conditions, and subject to the further condition p + r

26977 S/049/60/000/012/001/011
On multiply reflected and D214/D305
the phenomenon of total internal reflection from the free surface
OA is automatically allowed for. If p + r is less than unity, i.e.
there is some effective absorption qp then, subject to the above
assumptionsp there is also absorption at the free surface OA. This
is consistent with real media, since seismic waves reaching the
earth's surface from below may lose a fraction of their energy, ow-
ing to the non-perfect elasticity of the surface layers and scatter-
ing effects due to surface irregularities. As a first approximation
it is assumed that q is much smaller than p. Extensive formulas are
then derived giving the number of waves and their intensities at A.
In order to determine the total intensities at any point M, it is
sufficient to calculate the intensity of all such waves in the me-
dium shown in Fig. lb and then divide the result by 2. All the cal-
culations are confined to plane waves. The theory has been checked
by studying the transmission and reflection of waves in thin layers
of watert glass and iron. The emitters and receivers were in the
form of piezoelectric probes (Rochelle Balt). The experimental
arrangement is illustrated by Fig. 3. A detailed study was made of
the form, amplitude and period of the waves as a function of the
Card 3/7

26977 S/049/60/000/012/001/011

angle of incidence and the number of layers. For transmitted waves
it was found that the form of the waves remains practically inde-
pendent of the angle of incidence. The wave amplitude increases
monotonically with the angle of incidence. The increase is faster
for a larger number of layers. In the latter case the variation be-
comes linear and is more rapid for iron than for glass. The period
of the transmitted wave is larger than that of the incident wave
and increases with the number of layers. The increase is faster for
iron than for glass. For reflected waves the results are summarized
as follows. The form of the wave depends on the angle of incidence
but only very slightly. The amplitude decreases slightly as the
angle of incidence approaches the critical angle, and thereafter
begins to increase, particularly for a large number of layers. The
increase is larger for glass than for iron. The period of the re-
flected wave is smaller than that for the incident wave, and decrea-
ses slightly with the number of layers. In the region of the criti-
cal angle no special regularities were observed. The theoretical
and experimental studies showed that when the structure of the me-
dium is sufficiently complex the scattered waves become more inten-

se than the main reflection, and a point *Nrl d where the re-
flection is practically indistinguishable. This is analogous to
scattering light in a turbid medium, where for high turbiditieB an
object located in the medium disappears altogether. Model experi-
ments in which the covering medium has a strong velocity and densi-
ty differentiation provide infornution about the general behavior
of the waves. A scattering medium with large differentiation and a
small number of layers shouldo to some extent, behave as a medium
with weaker differnetiation, but a large number of layers. There
are 14 figures, 1 table and 8 Soviet-bloc references.

TITLE: Elastic waves with a generalized velocity in two-dimen-
sional bimorphous models
PERIODICAL; Akademiya nauk SSSR. Izvestiya, Seriya geofizicheskaya,
no. 4, 1961, 497 - 519
TEXT: The present paper is an extension of the work of J. Oliver
(Ref. 7: Earthq. Not., 27, No. 4, 1956) who suggested the use of
layered two-dimensional models for seismic waves in media with pa-
rameters varying continuously in space. The models are sheets of
variable or constant thickness which are stuck together in the samej
way as plywood; seismic waves are represented by ultrasonic pulses.
The present authors give a theory of long-wavelength longitudinal,
transverse and surface waves in bimorphous (two-layered) and poly-
morphous (many-layered) models. An experimental work on these wa-
ves is also reported; its aim was to find the possibilities and li-

mitations of two-layered and many-layered models. The work was limi-
ted to a study of vibrations, whose displacement vector lies-in the
plane of the two-dimensional model. These vibrations are analogous
to longitudinal, transverse SV and Rayleigh surface waves in three-
dimensional media. Elastic properties of quasi-anisotropic media,
consisting of successive isotropic layers with different properties,
were discussed in the three-dimensional case by Yu.V. Riznichenko
(Ref. 13: Izv. AN 333R, Ser. gogr. i geofiz. 8, no. 6, 1949). Riz-
nichenko's method is now used in the two-dimensional case. It is
assumed that the two layers in the model are thin compared with the
wavelength of elastic waves. General equations of the static theory
of elasticity and boundary conditions at the faces of the components
of the model, deformed by long longitudinal P and transverse S wa-
ves, are used to calculate the effective longitudinal and transvelse
elastic moduli and the velocities of propagation of P and S waves.
The expressions are obtained first for the bimorphous (two-layered)
case and are then generalized to a many-layered model. The veloci-
ties of propagation of long Rayleigh surface waves are calculated

for single-layered and many-layered plates. A nomogram is given
which relates the velocities of P, S and R waves with the Poisson's
ratio or for a massive sample and a plLte. The nomogram can be used
to find the effective value of d for a massive sample modelled by
a plate. The theoretical expressions were tested by experiments
using an ultrasonic pulse source HKA-4 (IKL-4). Piezoelectric
Rochelle salt transducers of X-450 cut were usedc their dimensions
were 10 x 10 x 10, 20 x 20 x 20 and 60 x 40 x 10 mm. The techniques
of longitudinal profiles and diagonal transmission were employed
to separate longitudinal and transverse waves. Good contact bet-
ween the working surfaces of the transducers and models was ensured
by using castor oil. Models were made of thin sheets of brass, Du-
ralumin, iron, Plexiglas (Perspex) and Getinaks (paper-filled phe-
nolformaldehyde resin). The two-layered models were stuck together
by a thin layer of paraffin wax, rubber plasticizer or glue 6~ -2
(BF-2). The maximum dimensions of the models were 500 x 600 x 8 mm.
The experiments showed that the theory given in the present paper
is essentially correct in the case of long waves. It was found that

if the thickness (h) of two-layered plates is much less then the
elastic wavelength (in practice h//1--< 0.1), then P, S and R waves
are generated in the plates. The attenuation of longitudinal and
transverse waves in two-layered plates obeys the same law as in
single-layered plates. This law is
A = A ex-p(- ax)
0 XV2 9
where AO is a constant, a is the absorption coefficient per unit
path length, and the term :~1/2 allows for spreading of the wave erw-
gy along a circular front. The absolute values of the absorption
coefficient a for P waves, and especially for S waves, are larger
in the two-layered model than in the individual plates (layers),
of which the model is made. A "gradient" medium, in which veloci-
ty varies with depthq was modelled by two wedge-shaped plates
stuck together. It was found that in such a medium even a small va-
riation of velocity with depth, which cannot be detected by means
of hodographs, affects very strongly the amplitudes of the longitu-
dinal waves. There are 16 figures, 2 tables and 24 references; 17

TITLE, Reference sections of the earth
PERTODICAL! Akademiya nauk SSSR. Vestnik, no. 8, 1961, 37-44
TEXT: The author describes a project concerning the reference sections of
the earth, which serves for a further development of the stereoscopic
picture of the earth, The earth is "irradiated" by means of natural and
mainly artificial seismic waves, and conclusions on its inner setup are
drawn. From the determination of general rules concerning the setup of
the earth, geophysicists at present proceed to the investigation of its
local peculiarities. Prospecting geophysics has already at its command
rational systems of observations in order to obtain precise information on
the depth structure. In prospecting seismology the observations of
reference sections are the bases of such investigations. For the -lobe as
a whole, the arcs oil great circles on the surface of the earth are iden-
tical with linear prospecting profiles, and the great-circle cross sections
through the center of the earth identical with nlane, vertical cross

sections. These cross sections and the reference sections corresponding
to them must be laid in such a way that they are of interest in
-eological and geophysical respect. A sufficient number of well equipped
seismic stations as well as sufficiently strong earthquake centers are
required. The lines of great circles for the primary reference sections
of the earth, as illustrated in the attached figure, are proposed, The
belt of circle no. I in Europe and Asia extends across the seismic areas
of the Tethys alpine range:- across the Pyrenees, Alps, Carpathian
lJountains, Crimea, Caucasia, the Pamirs, the Himalayas and across the
territory of Indochina; it further crosses the highly seismic area of the
Indonesian Islands, passes lowly seismic Australia, highly~seismic Nev,
Zealand, crosses the Pacific, and on the South American Continent it takes
its course across the highly seismic area in Peru, then across Brazil
and Guiana into the Atlantic with its moderately seismic belt, and returns
to Europe. Within this belt there are many well equipped seismic stations-
The belt of circle no, 2 proceeds across Arabia, the highly seismic areas
of Iran and Afghanistan, across the Soviet Union and the areas of the
Tethys belt, the mountain range of the Tian Shan, the Altai Mountains,
Pribaykal,ye as far as Kamchatka and the Pacific Plateau, This circle

further crosses the Pacific, the Hawaiian Islands, Tierra del Fuego,
Africa, Abyssinia, and returns to the Asian territory. These investi-a-
tions have only been started in the Soviet Union. At the Institut fiziki
Zemli im. 0, Yu. Shmidta Akademii nauk SSSR (Institute of Physics of the
Earth imeni 0. Yu. Shmidt of the Academy of Sciences USSR) a team is
dealing with this problem. At the recent Conference on Problems of
Seismic Magnitude and Energy held in Prague it was proposed by V. Karnik
and I. Vanek (Geophysical Institute of the Academy of Sciences of
Czechoslovakia), A. F. Zatopek (Prague University), 11. A. Sadovskiy,
N. V. Shebalin and the author (Institute o-f' Physics of the Earth imeni
0. Yu. Shmidt) to conduct these investigations jointly. The present
project concerning the reference sections of the earth is the realization
and supplementation of a proposal by V. V. Belousov, President of the
Mezhdunarodnyy geodezicheskiy i geograficheskiy soyuz (International
Geodetic and Geographic Union), the so-called "Upper Mantle Projectf9,
This proposal was approved by the 12th plenary meeting of this Union in '~Z
1960. There are I figure and 5 references: 3 Soviet-bloc and 2 non-
Soviet-bloc. The two references to English-language publications read

TITLE: Standardization of the earthquake magnitude scale
PERIODICAL: Studia geophysica et geodaetica, no. 1, 1962, 41-47
TEXT: The paper presents a proposal for standard methods of magnitude determinatien
C.
of both shallow and deep earthquakes, and describes the practical application of'
the suggested magnitude scale as agreed upon by Soviet and Czechoslovak seismolo-
gists at meetings held in Prague on December 7-14, 1960 and in early 1961. The
eroposal is based on the following postulates: (1) General acceptance of a unified
formula for the definition of the earthquake magnitude M
M = log (A/T)max+ 6( /A)
where A is the maximum ground amplitude of the wave considered (in microns), T is
the corresponding period in seconds, and 6 (,&.) is the calibrating function
expressing the 4lation between A/T and the epicentral distance which is

different for fferent wave typesy (2) General application of standard calibrating
functions 6 ( ~ ) for body and surface'waves as calculated according to the methods
recommended by the proponeritsl (3) Determination of a representative M for each
earthquake, to be represented by a simple arithmetic mean of magnitudes of a
single wave type as established according to the proposed standard method at many
stations. The detemination should be done by a proposed international center.
As of January 1, 1962, the magnitude ''M will be determined according to the propos-
ed standard method at all Czechoslovak and Soviet seismological stations. J.
Van& and J. Stelzner are the personalities mentioned. There are 2 tables and 20
references: 8 Soviet-bloc and 12 non-Soviet-bloc. The references to the four most
recent English-language publications read as,follows: J. Vanek, J. Stelzner, The
