VONA/Kamchatkan and Northern Kuriles Volcanic Activity
Issued: 20110613/0645Z

VOLCANO: KIZIMEN (1000-23)

Current AVIATION COLOR CODE: RED

Source: KVERT
Notice Number: 35-11
Volcano Location: 55°08'N, 160°19'E;
Area: Kamchatka, Russia
Summit Elevation: 8151 ft (2485 m)

Prognosis Volcanic Activity: Seismic and explosive activity of the volcano continues. Strong ash explosions up to 49,200-32,800 ft (15-10 km) ASL could occur at any time. Ongoing activity could affect international and low-flying aircraft.

Volcanic Activity Summary: Seismic activity of the volcano was changing during June 12-13. Although a magnitude of volcanic tremor in the area of Kizimen decreased from 04:52 UTC on June 12, and later additional sharp decreased from 08:45 UTC on June 12, ash plumes continued to detected on satellite images during June 12-13. According to satellite data, an ash plume extending about 470 mi (760 km) to the east from the volcano was noted at 04:08 UTC on June 13 (20110613/0408Z). According to the seismic and satellite interpretation, a height of ash plumes do not exceed 19,352 ft. A bright thermal anomaly continues to registering over the volcano.
According to seismic data, a magnitude of volcanic tremor in the area of Kizimen began increasing again from 04:00 UTC on June 13.



Volcanic cloud height: up to 19,352 ft (according to seismic or satellite interpretation)

Other volcanic cloud information: an ash plume extending to the east from the volcano > 470 mi on this time

Remarks: History of Kizimen eruptions is unknown. We have incomplete data about only one eruption in 1928-1929 which were likely moderate explosive (or explosive-effusive) events. Tephrachronological data point out several catastrophic eruptions in evolution of this volcano.

The KVERT Project 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) since 1993. 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 11 volcanoes, and other information to monitor activity at Kamchatkan and Northern Kuriles Volcanoes.
