Kamchatkan and Northern Kurile Volcanic Activity
INFORMATION RELEASE 33-06
Friday, July 14, 2006, 10:25 KDT (21:25 UTC on July 13)

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 the eruption of the volcano with ash explosions from the summit crater 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.

Eruptive activity at the volcano continues. According to seismic data, ash plumes rose up to 5.0 km (16,400 ft) ASL this week. A number of local shallow earthquakes was from 250 till 1000 per day. Spasmodic volcanic tremor was registering all days. A thermal anomaly over the volcanic crater was observed on July 09.

BEZYMIANNY VOLCANO: 55°58'N, 160°36'E; Elevation 2,895 m
CURRENT LEVEL OF CONCERN COLOR CODE IS YELLOW.

According to volcanologists' experience, growth of the lava dome continues. Lava effusion is probably occurring at the lava dome. The activity of the volcano could affect low-flying aircraft in the vicinity of the volcano.

Seismic activity did not exceed background levels. A fumarolic activity of the lava dome was observed on July 08 and 10. A thermal anomaly was noted at the volcano on July 08 and 10. Clouds obscured the volcano on 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. A fumarolic activity of the lava dome was observed on July 08 and 10. A thermal anomaly over the dome was noted on July 07-08. Seismic activity did not exceed background levels last week but ash explosions up to 6 km (19,700 ft.) ASL could occur at any time.

The Kamchatkan Volcanic Eruption Response Team (KVERT) is a non-commercial cooperative program of the Alaska Volcano Observatory (AVO, USA), the
Institute of Volcanology and Seismology (IVS) FED RAS and the Kamchatkan Branch of Geophysical Survey (KB GS) RAS (Russia). 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.
