Issued: 20111006/0525Z

VOLCANO: SHEVELUCH (1000-27)

Current AVIATION COLOR CODE: ORANGE
Previous AVIATION COLOR CODE: RED

Source: KVERT
Notice Number: 54-11
Volcano Location: 56°39'N, 161°21'E;
Area: Kamchatka, Russia
Summit Elevation: 3,283 m, the dome elevation ~8,200 ft (~2,500 m)

Prognosis Volcanic Activity: Explosive-extrusive eruption of the volcano continues. Strong ash explosions up to 32,800 ft (10 km) ASL could occur at any time. Ongoing activity could affect international and low-flying aircraft.

Volcanic Activity Summary: Explosive-extrusive eruption of the volcano continues. A new lava extrudes at the lava dome after strong explosions on October 03-05. Moderate seismic activity of the volcano continues. Ash plumes rose up to 19,680-29,520 ft (6.0-9.0 km) ASL on October 03-05, and up to 14,760-16,400 ft (4.5-5.0 km) ASL on October 05-06. Ash plumes extended to the north-east from the volcano on October 05-06. According to satellite data, a bright big thermal anomaly continues to noting over the lava dome.

Volcanic cloud height: 14,760-16,400 ft (4.5-5.0 km) ASL on October 05-06.

Other volcanic cloud information: Ash plumes extended to the north-east from the volcano on October 05-06.

The KVERT Project is a cooperative program of the Institute of Volcanology and Seismology (IVS) FED RAS and the Kamchatkan Branch of Geophysical Survey (KB GS) RAS since 1993. KVERT scientists is available in the office from 8:30 AM till 6:00 PM (KST) and by phone during the evenings. KVERT uses daily satellite imagery for 36 active volcanoes, information from remote scientific observation stations, real-time seismic data for 11 volcanoes, and other information to monitor activity at Kamchatkan and Northern Kuriles Volcanoes.
