Girina <girina@xxxxxxxxx> Kamchatkan and Northern Kurile Volcanic Activity INFORMATION RELEASE 21-06 Tuesday, May 09, 2006, 22:30 KDT (09:30 UTC) BEZYMIANNY VOLCANO: 55o58'N, 160o36'E; Elevation 2,895 m CURRENT LEVEL OF CONCERN COLOR CODE: RED The explosive eruption of Bezymianny volcano began at 08:21 UTC on May 09. An ash column rose up to 15 km (49,200 ft) ASL. Ash plumes extended to the south-southeast from the volcano. PREVIOUS INFORMATION RELEASE: Kamchatkan and Northern Kurile Volcanic Activity INFORMATION RELEASE 20-06 Tuesday, May 09, 2006, 19:35 KDT (06:35 UTC) BEZYMIANNY VOLCANO: 55o58'N, 160o36'E; Elevation 2,895 m CURRENT LEVEL OF CONCERN COLOR CODE: RED PREVIOUS LEVEL OF CONCERN COLOR CODE: ORANGE An explosive eruption is possible in the next one or two days. KVERT would expect this event to produce ash plumes as high as 8-10 km (26,000-33,000 ft) ASL. Seismic activity has increased. Intermittent spasmodic volcanic tremor has been occurring from 04:04 UTC on May 09. The number of hot avalanches from the lava dome is also significantly increased. A fumarolic plume at times containing small amounts of ash is visible. The height of gas-steam plume is > 7 km (23,000 ft) ASL now. A strong thermal anomaly at the dome was noted in satellite imagery on May 09. IF YOU HAVE ANY QUESTIONS OR CONCERNS, PLEASE CONTACT: Olga Girina, KVERT, IVS FED RAS E-mail: girina@xxxxxxxxx Tel.
