VOLCANOES OF KAMCHATKA

Abstract

The results of near real-time monitoring of the active Kamchatka volcanoes are described. Continuous monitoring was carried out using three remote methods: 1) seismic monitoring according to automatic telemetric seismic stations; 2) visual and video observation; 3) satellite observation of the thermal anomalies and the ash clouds. Daily information about volcanic activity is published in the Internet (http://www.emsd.ru/~ssl/ monitoring/main.htm) since February 2000. Annual results of seismic activity of the Northern (Shiveluch, Klu-chevskoy, Bezymianny, Krestovsky and Ushkovsky), Avacha (Avachinsky and Koryaksky), Mutnovsky-Gorely volcano group and Kizimen volcano are presented. 4983 earthquakes with КS=2.1–8.7 were located for Northern volcano group, 469 earthquakes with КS=1.6–6.1 – for Avacha volcano group, 459 earthquakes with КS=1.9–6.1 – Mutnovsky-Gorely volcano group, 220 earthquakes with КS=2.4–8.5 for Kizimen volcano and 238 earthquakes with КS=2.5–8.4 for Zhupanovsky volcano in 2014. Maps of epicenters, quantities of seismic energy and earth-quake distribution according to class are given. All periods of activity were fixed and investigated by remote me-thods in 2014: intensive volcanic activity of Shiveluch volcano associated with new cone, a con-tinuation of the seismic and volcanic activity of Zhupanovsky volcano after 56-year quite period and the ending of the summit explosive-effusive eruption of Kluchevskoy volcano in January-February.
