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.

The peculiarity of extrusive rocks of Mendeleev Volcano draws attention of researchers. According to previous research, the Mendeleev Volcano is telescoping caldera, composed of two shafts, the central cone and final extrusion. However, there are no any cuts that characterize the morphological structure of these elements, in the literature. Conducted in 1991, field studies have allowed us to design a more simple circuit of Mendeleev Volcano structure, as well as the study of the cut of Mechnikov Mountain's caldera shaft enabled us to offer the following explanation of the genesis of the extrusion of the Mendeleev Mountain.
Basalts that filled the peripheral focus of Mendeleev Volcano evolved till andesite-dacite by fractional crystallization. Fluid accumulation in the chamber has led to liquid immiscibility of residual magma to dacitic and andesitic compositions. Being thrown out with final explosion they formed a patch of contrast rocks: white dacitic pumices and black andesitic slags. Magma remnants of contrast compositions, losing fluids, were pressed out as andesite-dacite extrusions containing anomalous phenocrysts parageneses.
