A danger of ash explosions up to 10 km (32,800 ft) a.s.l. remains. Ongoing activity could affect international and low-flying aircraft. The extrusive-effusive eruption of the volcano continues: a lava is extruded out in the explosive crater of the Young Sheveluch, it is accompanied by powerful gas-steam activity, and sometimes an incandescence of the lava dome. A powerful gas-steam activity is also observed at the area of the Karan dome. Satellite data by KVERT showed a thermal anomaly over the volcano all week, excluding September 07 (dense cloudiness); plumes of resuspended ash extended for 650 km to the east and southeast of the volcano on August 31, and September 03-04. http://www.kscnet.ru/ivs/kvert/volc?lang=en&name=Sheveluch EBEKO VOLCANO (CAVW #290380) 50.69 N, 156.01 E; Elevation 1156 m (3792 ft) Aviation Colour Code is ORANGE The moderate explosive eruption of the volcano continues. Ash explosions up to 6 km (19,700 ft) a.s.l. could occur at any time. Ongoing activity could affect low-flying aircraft and airport of Severo-Kurilsk. The moderate explosive eruption of the volcano continues. According to visual data from Severo-Kurilsk, explosions sent ash up to 3.5 km a.s.l. on August 31, and September 02-05; ash clouds moved to the eastern directions of the volcano.

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.
