Дано описание извержений двух гигантских вулканов Камчатки, которые произошли в 1993 г. Наблюдались пирокластические потоки, лахары, пеплопады и взаимодействие лавовых и пирокластических потоков с ледниками. Приведены данные о росте андезитового купола и объеме выброшенного пепла вулкана Шивелуч, а также объеме излившейся андезитобазальтовой магмы Ключевского вулкана. Изучены последствия обоих извержений. Показано, что Шивелуч и Ключевской различаются по типу извержений и составу вулканических продуктов и поэтому оказывают разное влияние на окружающую среду. Отмечены существенные отличия в характере вулканической опасности.

Study is made for the first time on morphological peculiarities of microstructure of three samples from the unbroken marker ash layers of the Shiveluch volcano. In this paper we give the qualitative analysis of tephra structure, i.e. size and shape of particles and type of microstructure, describe structural relationships between deposit components, etc. and make the quantitative analysis of porosity of Sh2 and Sh1 tephra at magnification of 200 and 1,000. Hollow globules of volcanic glass were found for the first time in Sh2 ashes.

KUDRIAVY volcano on Iturup island in the Kuril arc is an active calc-alkaline volcano. It has not erupted this century; its current volcanic activity is characterized by hot (up to 910oC) gas jets which have been stable for at least 30 years. The composition of the gaseous emissions is typical of high-temperature fumaroles, but we report here the discovery of unusual subsurface sublimates associated with one gas jet—a sulphide mineral containing rhenium as the only cation. To our knowledge, this is the first reported occurrence of a pure rhenium mineral. The concentration of rhen-ium in the fumarole gas is only 2–10 p.p.b., so the condensation of pure rhenium sulphide from this gas requires both enrichment of rhenium by eight orders of magnitude and remarkable selectivity. Rhenium is generally believed to exist in only trace amounts at the Earth's surface, but our findings demonstrate that it can be readily mobilized, dispersed and concentrated by degassing magmas.

Attempt of modern interpretation and classification for long-term prediction of the types and parameters of future eruptions. Part 2 (1926-1991) // Volcanology and Seismology. 1994. Vol. 16. № 2. P. 93-114.
Previous data are summarized and new evidence is presented on the Avacha eruptions of 1926-1927, 1938, and 1945. The last eruption of January 1991 is described. The dynamics of the Avacha eruptive activity is considered for a period of 1737-1991. The eruptions are classified into different types. The type and size of a future event are predicted and the related hazard is assessed. It is recommended that the southwestern and southern sectors of the Avacha surrounding should be declared forbidden for residential or industrial construction because of a high volcanic hazard. -Journal summary

Attempt of modern interpretation and classification for long-term prediction of the types and parameters of future eruptions. Part 1 (1737-1909) // Volcanology and Seismology. 1994. Vol. 15. № 6. P. 649-665.
Some of the previous views on the style of the Avacha eruptions during 1737-1909 are revised on the basis of new data obtained by the authors. The types of eruptions, their geological and geomorphological effects, and the related volcanic hazards are reassessed. All eruptions were explosive events, except for the 1894-1895 extrusive-explosive eruption. The eruptions of 1737, 1779, and 1827 are classified as large, the others, as mild or medium-size events. -from Journal summary
