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.

The Paratunsky geothermal field has been in operation since 1964, mostly in a self-flowing mode, with a discharge rate of approximately 250 kg/s of thermal water at temperatures of 70–90°С (47 Mw, with the waste water having a temperature of 35°С). The water drawn from the field is used for local heating, spa heating, and for greeneries in the villages of Paratunsky and Termal’nyi (3000 residents). The potential market of thermal energy in Kamchatka includes Petropavlovsk-Kamchatskii (180000 residents), Elizovo (39 000), and Vilyuchinsk (22 000). The heat consumption in the centralized heating systems for Petropavlovsk-Kamchatskii is 1 623 000 GCal per annum (216 Mw). A thermohydrodynamic model developed previously is used to show that the Paratunsky geothermal reservoir can be operated in a sustainable mode using submersible pumps at an extraction rate of as much as 1375 kg/s, causing a moderate decrease in pressure (by no more than 8 bars) and temperature (by no more than 4°С) in the reservoir. Additional geothermal sources of heat energy may include the Verkhne-Paratunsky and Mutnovsky geothermal fields.

Isotope-geochemical material for Pliocene-Quaternary volcanoes of the Kamchatka region is generalized on a cartographic basis. The Sr-isotope anomalies of moderate and elevated radiogenicity, geochemically confirmed, are spatially conjugated. This made it possible to interpret these anomalies not only as a reflection of mantle plume material in the composition of volcanic rocks, but also of its hybrid environment, as a consequence of plum-lithosphere remobilization. The presence of multi-directional geochemical trends made it possible to propose the concept of moving boundary values for the composition of indicator rocks of the intraplate type and adakites, which significantly expanded the possibilities of their diagnostics. The isotope-geochemical heterogeneity of basaltoids of the region is generally determined by the peculiarities of concentration of rocks with intraplate and adakite geochemical characteristics, which allows considering the asthenospheric diapirism as the main factor of petrogenesis of Pliocene-Quaternary volcanism in Kamchatka.

The actual collective monograph presents the results of both theoretical and experimental studies of the multi-disciplinary problem on volcanic hazard assessment and development of techniques for prediction of catastophic eruptions. The volcanism of Kamchatka and other regions of Russia has been analyzed. On the basis of geological, volcanological and tephrachronological studies including radiocarbon dating, there have been defined certain groups of volcanoes on different stages of evolution. At the same time the problem of determination of the internal structure of volcanic dome using modem theoretical methods and technologies is well investigated. The new techniques of estimation of volcanic hazard were developed. Whenever ti is required, theoretical approaches are confirmed by results of in-field observations.

The book will satisfy the needs of Earth sciences specialists from a variety of backgrounds, volcanology, geo-mechanics, ecology, industrial constuction applications and hazard assessment.
