Ash explosions up to 10-15 km (32,800-49,200 ft) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft. A growth of the lava dome continues, a strong fumarolic activity, and an incandescence of the lava dome and hot avalanches accompanies this process. Satellite data by KVERT showed a thermal anomaly over the volcano all week; gas-steam plumes containing some amount of ash extended for 370 km to the southwest, east and southeast of the volcano during all week. http://www.kscnet.ru/ivs/kvert/volc?lang=en&name=Sheveluch KARYMSKY VOLCANO (CAVW #300130) 54.05 N, 159.44 E; Elevation 1486 m (4874 ft) Aviation Colour Code is ORANGE A moderate eruptive activity of the volcano continues.

KVERT scientists are available in the office from 8:30 AM till 6:00 PM (KST) 7 days in week and by phone during the evenings since 2005. KVERT produces daily satellite monitoring (since 2002 till now) of Kamchatkan and Kuriles Volcanoes to using the information system (IS) “Remote monitoring of the activity of Kamchatka and Kuriles volcanoes (VolSatView)”, which was created in 2011-2014 the joint efforts of the scientists of KVERT IVS FEB RAS, the Space Research Institute RAS, the Computing Center FEB RAS and the Far Eastern Scientific Center Planet. IS continues to evolve. KVERT analyses information from remote scientific observation stations and seismic data for volcanoes: Alaid, Avachinsky, Bezymianny, Gorely, Karymsky, Kizimen, Klyuchevskoy, Koryaksky, Mutnovsky, Plosky Tolbachik, Sheveluch, Ushkovsky, Zhupanovsky (from the Kamchatkan Branch of Geophysical Survey RAS); and other information to monitor activity at Kamchatkan and Kuriles Volcanoes.
