Abstract

There are 29 active volcanoes in Kamchatka. The monitoring of activity of Kamchatkan volcanoes is necessary in order to estimate volcanic danger. It is very important to warn the population and administration, ministry of the emergency situation about a possible eruption in proper time. The purpose of this monitoring is reducing risk from volcano hazards and providing safety to air travel in area the peninsula Kamchatka. Kamchatkan Branch of the Geophysical Survey (KBGS) RAS has being monitored volcanic activity since February 2000 (http://emsd.iks.ru/ssl/monitoring/main.htm) using three remote methods: 1) Seismic monitoring is a leading method. Processing and interpretation of the data from automatic telemetric seismic stations. 2) Visual and video observation. 3) Satellite observation in the form of processing and interpretation of the AVHRR sensor data from NOAA satellite. KCCM (Kamchatsky Centre of Communication and Monitoring) receives NOAA data. 186 earthquakes were processed and placed in the catalogue of Avachinskaya volcano group in 2006 (15 earthquakes have ML ≥ 1.25). Catalogue of Northern volcano group includes 5288 earthquakes (4631 earthquakes have ML ≥ 1.25). The additional information about volcanic earthquakes (not located earthquakes, volcanic tremor) published in the Internet: http://emsd.iks.ru/ssl/ monitoring/main.htm, a section is "Earthquake". All active periods of Kamchatkan volcanoes were fixed and investigated by remote methods in 2006. Two short-term explosion eruptions of Bezymianny volcano occurred in May and in December. Both eruptions were predicted successfully without false alarms. Karymsky volcano continued to be in a stage of eruption. Sheveluch volcano began to erupt in December after one-year break.
