The article describes the affected woody vegetation on the slope of Sarychev Peak, the Kuriles, in 2007 and discusses some reasons that could have lead to the vegetation death. Besides, the article provided a conclusion that a large-scale destruction of alder elfin wood was caused by gas emission, chiefly by SO2.

The results of electrical exploration works in the area of Pauzhetsky and Nizhne-Koshelevsky geothermal deposits are presented. In 2012 y. works by VES method were carried out on the profile, crossing structures of Pauzhetsky deposit which were defined earlier. Sounding was made in 35 spots. In 2013 electrical exploratory works by VES method were carried out in the area of Nizhne-Koshelevsky geothermal deposit. Souding was made in 17 spots. Preliminary data of apparent resistance allocation to depth were drawn by results of the works. The areas permeable for hydrothermal liquors or gas-vapor heat-transfer were defined.

В докладе на примере спутникового сервиса VolSatView показываются возможности информационной системы, созданной для оперативного обеспечения данными дистанционного зондирования работ по мониторингу вулканической активности на Камчатке и Курилах. В работе описана архитектура такой системы, а также текущие возможности и перспективы её развития. На примере сервиса VolSatView описываются инструменты доступа к оперативной спутниковой информации, а также удобные инструменты для анализа такой информации.

Приведены новые данные по макро- и микрокомпонентному составу термальных вод, разгружающихся в бассейне р. Юрьевой (о. Парамушир, Северные Курильские острова). Прослежены изменения в химическом составе и физико-химических показателей вод Верхне-Юрьевских источников, произошедшие с начала их исследований в 1957 г. до 2010 г. Дана предварительная оценка геохимической работы источников по состоянию на 2010 г. Рассмотрены условия формирования термальных вод.

The Kekuknai massif was formed in the course of tectono-magmatic activity that involved the origin of a shield volcano and a caldera depression with associated emplacement of extrusions that terminated in intense post-caldera areal volcanism. The mineralogical compositions of the massifs rocks have been considered in detail. The use of previously known and newly developed indicator properties of rock-forming minerals allowed the reconstruction of the general picture of the magmatic melt evolution and conditions of rock crystallization (various fluid and water saturation levels, as well as the oxidation state of the system). Essentially island-arc or intraplate characteristics of the massif s rock compositions are found at different stages of development of a single fluid-magmatic system. Decompression evolution of the parent deep-seated basanitic magma occurred via occurrence in intermediate magma chambers of daughter magmas of trachybasalt (pre-caldera stage) or hawaiite (areal volcanism) composition. Subsequent emanate-magmatic differentiation of these melts, combined with crystallization differentiation under changing P-T-f0l conditions, resulted in the formation of the entire diversity of the Kekuknai rocks
