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 paper presents data that describe the Kuril Island Arc volcanic activity over the 2012-2015 period collected using satellite monitoring and visual observations, as well as the results of field studies at the active volcanoes. The authors analyzed eruptions of Ivan Grozny, Kudryavy (Iturup Island), Snow (Chirpoi Island), Chirinkotan (Chirinkotan Island), Sinarka (Shiashkotan Island), Chikurachki (Paramushir Island), and Alaid (Atlasov Island) volcanoes.

The paper presents data describing volcanic activity in the Kuril Islands in 2016. The eruptions of Alaid (Atlasova Island), Ebeko, Chikurachki ( Paramushir Island), Chirinkotan (Chirinkotan Island) and Snow (Chirpoi Island) volcanoes are considered.

The paper provides data characterizing the volcanic activity in the Kurile Islands in 2017. The authors studied eruptions of Ebeko Volcano (Paramushir Island), Chirinkotan (Chirinkotan Island) and intensification of activity of Sarychev Peak (Matua Island) and Kudryavy (Iturup Island) volcanoes.

Data showing the activity of the volcanoes in the Kurilе Island Arc in the XXI century are given. The volcanic eruptions at the volcanoes Chikurachki, Chirinkotan, Ebeko, Sarychev Peak, Ekarma, Ivan Grozny, Alaid and Snow were considered. Increase of steam-gas activity was observed at the volcanoes Sinarka (Shiashkotan Isl.), Berg (Urup Isl.), Severgin Peak (Kharimkotan Isl.) and Kudryavy (Iturup Isl.). It is shown that the brief (from a few hours to several days) explosive eruptions of weak and moderate intensity (VEI = 0–3) prevailed. The most active were volcanoes Chikurachki (8 events) and Ebeko (4 events) (Paramushir Isl.). The strongest eruption during the reporting period was explosiveeffusive eruption of Sarychev Peak volcano in 2009; the longest were effusive eruptions of Snow Volcano (Chirpoi Isl.) in 2012–2016. The total volume of erupted material for the years 2000–2016 does not exceed 0.3–0.4 km3.
