Happy Volcanologist Day!

VONA Weekly
Kamchatkan and Northern Kuriles Volcanic Activity
KVERT INFORMATION RELEASE 24-12
March 29, 2012, 22:45 UTC (March 30, 10:45 KST)

KVERT IVS FED RAS monitor 30 active volcanoes of Kamchatka and 6 active volcanoes of Northern Kuriles.

KVERT (IVS FED RAS) scientists examined satellite information each day to look for evidence of volcanic unrest since 2002. Not all of these volcanoes had eruptions in historical time, however they are potentially active and therefore are of concern to aviation.

SHEVELUCH VOLCANO (1000-27)
56°38'N, 161°19'E; Elevation 3,283 m, the dome elevation ~8,200 ft (~2,500 m)
AVIATION COLOR CODE IS ORANGE

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

Explosive activity of the volcano continues: ash plumes rose up to 23,000 ft (7.0 km) a.s.l. each day on March 25-26 and 28. According to visual and satellite data, a viscous lava flow continues to effuse into the explosive crater of 2010 eruption. Strong and moderate fumarolic activity of the lava dome was observing on March 24-27 and 29. According to satellite data, ash plumes extended for about 120 mi (192 km) to the east and southeast of the volcano on March 25-28; a weak thermal anomaly was noting over the lava dome all week.

KARYMSKY VOLCANO (1000-13)
54°03'N, 159°27'E; Elevation 4,874 ft (1,486 m)
AVIATION COLOR CODE IS ORANGE

Explosive activity of the volcano continues. Ash explosions up to 19,700 ft (6 km) ASL could occur at any time. Activity of the volcano could affect low-flying aircraft.

Moderate seismic activity of the volcano continues; according to seismic data, possible ash plumes rose up to 8,200 ft (2,5 km) a.s.l. on March 22-26. According to satellite data, a thermal anomaly was registering over the volcano almost all week.

KIZIMEN VOLCANO (1000-23)
55°08'N, 160°19'E; Elevation 8,151 ft (2,485 m)
AVIATION COLOR CODE IS YELLOW

Effusive eruption of the volcano continues: the large lava flow effuses on the eastern volcanic flank. Strong gas-steam volcanic activity and moderate hot avalanches accompanies this process. Aerosolic plumes, and small ash plumes from hot avalanches, could affect low-flying aircraft.

Moderate seismic activity of the volcano continues. Video data and satellite imagery showed that the lava flow continues to effusing on the eastern volcanic flank. Hot avalanches accompany the lava flow effusion. Strong gas-steam activity of the volcano at video camera and a big thermal anomaly at satellite images were noting all week.

BEZYMIANNY VOLCANO (1000-25)
55°58'N, 160°36'E; Elevation 9,455 ft (2,882 m)
AVIATION COLOR CODE IS YELLOW

Moderate activity of the volcano continues. Ongoing activity could affect low-flying aircraft.

Seismic activity was low last week. A viscous lava flow continues to effuse on the southern lava dome slope - strong and moderate gas-steam activity of the volcano accompanies this process. According to satellite data, a thermal anomaly was registering over the volcano on March 23, 25 and 26; clouds obscured the volcano in the other days of week.

GORELY VOLCANO (1000-07)
52°33'N, 158°02'E; Elevation 5,996 ft (1,828 m)
AVIATION COLOR CODE IS YELLOW

Moderate activity of the volcano continues. Ongoing activity could affect low-flying aircraft.

There was not seismic data from February 05 till present by technical reasons. Moderate gas-steam activity of the volcano was observing all week. According to satellite data, a thermal anomaly was registering over the on March 24.

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 was available in the office from 8:30 AM till 6:00 PM (KST) 7 days in week in 2005-2011. Now KVERT scientists is available in the office from 8:30 AM till 6:00 PM (KST) in the work days and by phone during the evenings. KVERT (IVS FED RAS) analyses daily satellite imagery; information from remote scientific observation stations; real-time seismic data for 11 Kamchatkan volcanoes (data from KBGS RAS); and other information to monitor activity at Kamchatkan and Northern Kuriles Volcanoes.
