It was found that thes~~ craters were as- sociated with the ec.ge of a newly formed sirieclise (Russian: "sinek].iza"), at thE~ forming of which thick layers of tuffs were involved. On the basis of these data .it became apparent that the pyroclastic material, of which the tuffs are composed, were effused through. volcanic tubes, and that numerous such tubes ~sre likely to be found at the periph�ry of the deep 3e- pressions(sineclise).
