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.

В статье изложены результаты наблюдений за состоянием, сейсмическим режимом и деформациями вулканов Северной группы: Ключевского, Безымянного и Шивелуча, проявлявших активность в 1988—1989 гг. В течение исследуемого периода на Ключевском вулкане на фоне продолжающегося эксплозивно-эффузивного извержения вершинного кратера наблюдалось интенсивное растрескивание вулканической постройки в секторе, заключенном между северо-восточным и южным направлениями, на абсолютных отметках от 2000 м до вершины вулкана За период 1988—1989 гг. произошло два длительных побочных извержения на отметках, близких к 4000 м, с объемом 0,03 км3 каждый. В целом расход извергнутых продуктов за прошедшие два года равен 0,9 м3/сек, т е. был близок к среднему расходу за миллионы лет — 1,0 м3/сек.
На вулкане Безымянный в марте 1988 г. закончилось эффузивное извержение, длившееся с января 1987 г. 2—3 августа 1989 г. произошло еще одно эксплозивно-эффузивное извержение. По характеру они оба существенно не отличаются от извержений последних лет.
На вулкане Шивелуч увеличилось количество эксплозивных извержений (взрывов) и наметилась тенденция к образованию кратерной воронки, охватывающей центральную и западную части активного купола

On the example of the large volcanotectonic structure absolute and relative volumes have been estimated for all principal types of rocks: basalts, andesitebasa'ts, andesites and dacites; the dynamics of their accumulation and distribution in Low-Pliocene, Upper-Pliocene and Quaternary volcanic cycles, in the structure and in various tectonic settings has been restored for the first time. The leading role of the basic volcanism in the structure formation has been established. A stable tendency of the earth's crust to extend has been revealed here in Pliocene - Quaternary.
