The construction of digital 3D models of volcanoes is now made much easier and faster after the JPL/NASA specialists have carried out an interferometer radar survey of the Earth's surface (SRTM - Shuttle Radar Topographic Mission). Computer processing of the interferometer measurements in the SIR-C/X-SAR wavelength range (L - 23 cm, С - 5.6 cm and X - 3.1 cm) enabled high accuracy to be attained in construction of 3D topographic models, marking more data on these in the geographic coordinate system, and continuing on this basis to develop "digital layers" with data from new eruptions plotted on them, resulting in quantitative estimation of erupted volumes in real time. This method also allows one to model possible locations of new eruptive centers based on fast seismological forecasts of eruptions in addition to predicting possible routes of new lava and pyroclastic flows, mud streams and labors, and assessing the range and geologic effects of an eruption, and its ecologic impact

Приведены 34 14С датировки для плейстоценовых отложений Центральной Камчатской депрессии в диапазоне от "запредельных" значений (>55000 лет) до 10000 лет. Даты получены по древесине и торфу из межледниковых аллювиальных отложений, а также по погребенным почвам и остаткам млекопитающих из лессовидных покровных супесей. Ледниковые отложения II стадии позднеплей-стоценового оледенения датированы возрастом 21000 лет по найденным в них остаткам мамонта. В верхненеоплейстоценовых отложениях депрессии фиксируются многочисленные мощные прослои вулканических пеплов, связанные с крупнейшими извержениями в Срединном хребте и в пределах Восточной вулканической зоны Камчатки.

The reports, introduced on scientific session of the First International Kuril-Kamchatka field workshop, are published in this book. Papers are devoted to studying the geothermal and mineral resources of modern volcanism areas and, first of all, to researching the long-living ore-forming hydrothermal-magmatic systems of insular arcs. The following scientific themes in six sections are submited: (1) geothermal resources, common problems; (2) structure, thermal and power supply of hydrothermal-magmatic systems; (3) petrology, mineralogy and geochemistry of rocks; (4) geochemistry and dynamics of gases and natural waters; (5) ore mineralization in geothermal systems; (6) seismicity of geothermal regions and geotechnological aspects. The tendencies of development of researches, the new ideas and concrete actual materials on an example of geothermal fields of Kuril Islands and Kamchatka, and also New Zealand, Philippines, USA etc., are discussed. The new tasks of geothermal and mineral resources studying are formulated.
The book is prepared for specialists in Earths sciences, geologists, volcanologists, hydrogeologists, geochemistris, perologists, mineralogists etc.; for teaches, post-graduate students and students, all readers which are interested by problems of a geothermie and hydrothermal mineral-ore formation.

Close cooperation between researchers at the Alaska Volcano Observatory, USA, the Institute of Volcanic Ge-ology and Geochemistry, Far East Division, Russian Academy of Sciences, and the Kamchatkan Experimental and Methodical Seismological Department, Geophysical Service, Russian Academy of Sciences within the framework of the aviation flight safety program carried out by KVERT (the Kamchatkan Volcanic Eruption Response Team) resulted in a successful forecast of the Bezymianny eruption, all organizations concerned be-ing warned before the event. We describe the precursory phase and evolution of this explosive eruption, as well as its products. The explosive phase lasted one day, the effusive one during about a month. The eruption pro-duced a block and ash pyroclastic flow of merapi type on the volcano's slope and a viscous lava flow on the slope of its dome. The Volcanic Explosivity Index (VEI) is about 2.
