Radiocarbon dating is widely used when studying recent volcanic activity in the Kamchatka Peninsula due to the abundance of organic matter that is associated with the volcanic deposits. Here, we present the results of 14C dating of major volcanic events within the active South Kamchatka volcanic zone. South Kamchatka includes 8 recently active volcanic centers (stratovolcanoes, calderas, and large craters) that have been erupting during the Holocene. Their tephras represent useful markers for both the southern part of the peninsula and the Northern Kurile Islands. Since these marker tephra layers facilitate stratigraphic and tephrochronological studies in this area, it was important to determine their ages. We have obtained 73 new individual 14C dates on paleosol, peat, charcoal, and wood associated with the marker tephra layers, then complemented these data with 37 earlier published dates and analyzed the resulting data set. We selected the reliable dates and then obtained average 14C ages of marker tephra layers. The details of these procedures, as well as brief descriptions of South Kamchatka Holocene eruptions and their tephra beds, are presented in the paper.

Справочник содержит характеристику около трех тысяч вулканов земного шара, сгруппированных по вулканическим поясам и другим районам проявления вулканизма. Этим поясам и районам предшествует их общая геолого-географическая характеристика. Сведения о вулканах включают географическое положение, морфологию, геологическую структуру, активность и т.д. Книга рассчитана не только на специалистов, но и на более широкий круг читателей.

"Каталог действующих вулканов Камчатки" является сводкой наших знаний на 1 января 1957 г. по действующим вулканам Камчатки.

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.

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 монографии рассматривается широкий круг вопросов, касающихся геологического строения, тектоники, вулканизма и структур Южно-Камчатской вулканической зоны, обосновывается специфика ее геодинамических условий по сравнению с другими зонами Камчатки и Курильских островов. Большое внимание уделено характеристике четвертичного вулканизма.
Детально охарактеризована крупнейшая на Камчатке Паужетская кольцевая вулкано-тектоническая структура, являющаяся примером долгоживущего вулканического центра, развивающегося в течение по крайней мере 15 млн. лет. Сделано предположение о расположении этой структуры над конвекционным потоком вещества и энергии, поднимающимся из верхней мантии.

This paper describes a large landslide that occurred on Zheltovsky Volcano in summer 2012. The article describes main features of the volcanic edifice and considers parameters of the landslide. The landslide was likely caused by the altered rocks in the summit area as well as water infiltration during snow melting. No significant seismic or meteorological events had been registered immediately prior to the landslide. This example shows that large landslides at the volcanic edifices may occur without catastrophic precursors, which makes the hazard assessment more difficult. The paper is based exclusively on the remote sensing data most of which are available online from open sources.

This book is the first work that provides the ultimate data about chemical composition of the Kamchatka Quaternary andesites. Besides the book provides data about a phase analysis of andesites, geochemical composition, REE composition and isotopic analysis of strontium, neodymium and oxygen. The analyses are prominent for their stratification and accurate geological positioning. This allows understanding how the geological events alternated. The paper is focused on the petrogenetic peculiarities of tholeiitic (the 1st type of mantle genesis) and calc-alkali (the 2nd type of mantle-crust genesis) andesites. The book stresses that petrochemical, petrological and isotopic-geochemical correlators play a great role in distinguishing of those two types of andesites. On the basis of petrochemical database we distinguished three trends of the volcanites differentiation: stable, unstable and intermediate. These trends are supposed to be used for the determination of the volcanic activity character and types of the volcanic eruptions.
This book will be helpful as a reference guide to volcanologists, petrographers, geochemists and geologists, to those who study the genesis of volcanic rocks.
