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.

This book presents new data on the composition, genesis and metal content of hydrothermal solutions in the areas of active volcanism and their significance in mineral formation.

Results of complex study of pyroclastic deposits from Bezymianny and Schiveluch volcanoes are present in this work. Comparative characteristics of engineering-geological features are given for various genetic types of pyroclastic deposits from andesitic volcanoes, as well as for pyroclastic deposits from andesitic and basaltic volcanoes on the whole.
Criteria for distinguishing genetic types of pyroclastic deposits from andesitic volcanoes have been substantiated.

The monograph presents various data about the volcanoes of Kamchatka and describes the possibilities of studying them based on the integrated use of remote sensing, ground-based observation and numerical simulation methods and technologies. Considerable attention is paid to the construction and application of the information systems that today provide operational monitoring and studies of volcanic activity, which have been jointly developed in the recent years by the experts from the Institute of Volcanology and Seismology of the Far East Branch of the Russian Academy of Sciences (IVS FEB RAS) (Petropavlovsk-Kamchatsky), Space Research Institute RAS (Moscow), Computing Center FEB RAS (Khabarovsk) and the Far East Branch of the Research Center “Planetа” (Khabarovsk). The results of complex studies of explosive volcanic eruptions and the potential hazards of the Kamchatkan active volcanoes to the population and aviation are presented which are obtained by the scientists of IVS FEB RAS, particularly exploring the new methods, technologies and systems described in the monograph.

Работа состоит из двух частей. В первой из них приводятся подробные данные о всех голоценовых вулканах и большинстве плейстоценовых вулканических массивов. Для каждого вулкана приведены данные о форме, строении, петрографии и истории развития. Отдельная глава посвящена петрографическим и петрохимическим особенностям курильских лав. Все вулканологические данные увязаны с особенностями строения земной коры и верхней мантии.
В монографии впервые в мировой вулканологической литературе приводятся такие подробные данные по большому кругу вопросов, на столь обширной территории.
Во второй части рассматриваются петрохимические особенности, а также имеющиеся сведения о строении земной коры и верхней мантии в островных и вулканических дугах, внутри океанических и внутриконтиненталъных вулканах Тихоокеанской области. На большом новом материале подтверждаются выводы о мантийном питании вулканов и о существовании двух главных классов пород — океанического и континентального. Дается схема эволюции вулканизма, как отображение эволюции верхней
мантии.
Книга рассчитана на геологов широкого профиля, а также геофизиков и геохимиков.

The book provides a systematic description of active volcanoes of Kamchatka — one of the most active volcanic regions of the world. Distribution, shape and activity of the volcanoes, their position in complex and long-lived volcanic centres, as well as their geologic structure and composition are presented.
The book is illustrated with colour maps, schemes, and sketches. Over 300 colour photographs show volcanic landscapes, diverse volcanic forms (cones, craters, lava flows, calderas, etc.) and various manifestations of post-volcanic activity (hydrotherms, famous Kamchatka geysers).
Concise, lavishly illustrated with colourful and high-quality photographs, the book makes an interesting and useful reading not only for specialists (volcanologists, geologists, geochemists, geophysicists, geographes, etc.) but for a bioad readership as well. The publication is unique and unparalleled in scientific literature. The text is presented in Russian and in English.
This monography is written by scientists from the Institute of volcanology, Far East Division, the Academy of Science of the USSR.

The Eastern and Southern zones of Kamchatka arc presented in the second volume. They are characterized by a weaker activity, and their volcanoes arc not as large and powerful as those of the Northern Group. But volcanic manifestations here are more diverse. Half of the volcanoes are connected with collapse calderas. Huge hydrothermal systems are here too. Among them, the famous Valley of Geisers is one of the most picturesque places on Earth.
The book is abounded with colour photographs, maps, schemes, and sketches. They enable the reader to catch uniqueness of these colourful sights and will be of interest not only for specialists in volcanology and geology, but also to a great number of nature lovers.
