******************************* Kamchatkan and Northern Kurile Volcanic Activity INFORMATION RELEASE 43-06 Friday, September 22, 2006, 10:30 KDT (21:30 UTC on September 21) ******************************* SUMMARY OF LEVEL OF CONCERN COLOR CODES: KAMCHATKA: KARYMSKY: ORANGE SHEVELUCH and BEZYMIANNY: YELLOW KLYUCHEVSKOY, TOLBACHIK PLOSKY, KIZIMEN, AVACHINSKY, KORYAKSKY, MUTNOVSKY and GORELY: GREEN NORTHERN KURILE: EBEKO, CHIKURACHKI and ALAID: GREEN KARYMSKY VOLCANO: 54°03'N, 159°27'E; Elevation 1,486 m. CURRENT LEVEL OF CONCERN COLOR CODE IS ORANGE. Seismic data and satellite observations indicated that a moderate ash eruption of the volcano continues. Ash explosions up to 6 km (or 19,700 ft.) ASL are possible. The activity of the volcano could affect low-flying aircraft in the vicinity of the volcano. According to seismic data, a number of weak local shallow earthquakes was 40-200 per day. A thermal anomaly over the volcanic crater was noted on September 18-19. According to visual data by volcanologists who worked at the area of the volcano, a height of ash explosions from the volcano was about 2,300 km (7,500 ft)ASL on September 19. Ash plumes extending from 16 to 40 km to the south-west and south-east from the volcano were noted at satellite images on September 18-19. BEZYMIANNY VOLCANO: 55°58'N, 160°36'E; Elevation 2,895 m CURRENT LEVEL OF CONCERN COLOR CODE IS YELLOW. Seismic data and satellite observations indicated that growth of the lava dome continues. The activity of the volcano could affect low-flying aircraft in the vicinity of the volcano. Several weak shallow earthquakes were registered this week. A fumarolic activity of the lava dome was noted during periods of visibility of the volcano. A thermal anomaly over the lava dome was noted on September 19-21. Clouds obscured the volcano in the other days. SHEVELUCH VOLCANO: 56°38'N, 161°19'E; Elevation 3,283 m, the dome elevation ~2,500 m. CURRENT LEVEL OF CONCERN COLOR CODE IS YELLOW. Growth of the lava dome continues. Ash explosions up to 6 km (19,700 ft.) ASL could occur at any time. The activity of the volcano could affect low-flying aircraft in the vicinity of the volcano. Seismic activity was at background levels all week. Several weak earthquakes were registered at the volcano last week. A fumarolic activity of the lava dome was observed during periods of visibility of the volcano.

KVERT staff is available in the office from 8:30 AM till 6:00 PM (KST or KDT) and by phone during the evenings. KVERT uses daily satellite imagery, information from remote scientific observation stations, real-time seismic data for 10 volcanoes, and other information to monitor activity at Kamchatkan and Northern Kurile Volcanoes.
