VONA/Kamchatkan and Northern Kuriles Volcanic Activity
Issued: 20110612/0420Z

VOLCANO: KIZIMEN (1000-23)

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

Source: KVERT
Notice Number: 34-11
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 increases. 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 significantly increases. A magnitude of strong volcanic tremor in the area of Kizimen increased from 07:00 UTC on June 11, additional from 17:00 UTC on June 11, and some more from 02:00 UTC on June 12. According to the seismic interpretation, probably seven strong explosions occurred on June 11 (for height 13,120-19,352 ft), and three (for height 16,400-19,352 ft) - on June 12 last time. According to satellite data, a wide ash plume extending about 83.9 mi (135 km) to the south-east from the volcano was noted at 00:12 UTC on June 12 (20110612/0012Z) and earlier. A bright thermal anomaly continues to registering over the volcano.

Volcanic cloud height: Unknown
Other volcanic cloud information: a wide ash plume extending to the south-east from the volcano 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.
