Kamchatkan and Northern Kuriles Volcanic Activity
KVERT INFORMATION RELEASE 29-12
May 03, 2012, 23:30 UTC (May 04, 11:30 KST)

KVERT monitor 30 active volcanoes of Kamchatka and 6 active volcanoes of Northern Kuriles. Not all of these volcanoes had eruptions in historical time, however they are potentially active and therefore are of concern to aviation.

SUMMARY OF AVIATION COLOR CODES:

KAMCHATKA
Real-time seismic data (from the Kamchatkan Branch of Geophysical Survey RAS: www.emsd.ru):
SHEVELUCH and KARYMSKY: ORANGE
KIZIMEN, BEZYMIANNY and GORELY: YELLOW
KLYUCHEVSKOY, TOLBACHIK PLOSKY, USHKOVSKY, KORYAKSKY, AVACHINSKY, MUTNOVSKY: GREEN

No seismic data: ICHINSKY, VYSOKY, GAMCHEN, KOMAROV, KRONOTSKY, KRASHENINNIKOV, KIKHPINYCH, TAUNSHITS, MALY SEMYACHIK, ZHUPANOVSKY, OPALA, KSUDACH, ZHELTOVSKY, ILIINSKY, KOSHELEV, KAMBALNY, DIKII GREBEN, KHODUTKA and KHANGAR: GREEN

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 continued: seismic data and visual observation showed ash plumes rose up to 13,200 and 17,800 ft (4.0 and 5.4 km) a.s.l. on April 26 and May 01, respectively. 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 accompanies the lava flow effusion. Ash explosions up to 5 km a.s.l. was observed on May 01. Satellite data showed ash cloud was moving for about 167 mi (270 km) to the north-east of the volcano on May 01; a weak thermal anomaly was noting over the lava dome on April 28-29 and May 01 and 03.

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 7,600 ft (2.3 km) a.s.l. on April 26-27 and May 02. According to satellite data, gas-steam plume was extending 40 mi (65 km) to the south-east of the volcano on April 27; a thermal anomaly was registering over the volcano on April 27 and 29-30 and May 02-03.

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.

Activity of the volcano is gradually decreasing, but remain moderate. Video data and satellite imagery showed that the lava flow continues to effusing on the eastern volcanic flank. Hot avalanches and strong gas-steam activity accompany the lava flow effusion. According to satellite data, a thermal anomaly was registering over the volcano on April 28-30 and May 01 and 03.

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 April 28-29 and May 03.

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. Video data showed the volcano was quiet or obscured by clouds. According to satellite data, a thermal anomaly was registering over the volcano on April 28 and May 02.

In Russia, KVERT, on behalf of the Institute of Volcanology and Seismology (IVS) FED RAS, is responsible for providing information on volcanic activity to international air navigation services for the airspace users.

KVERT scientists was available in the office from 8:30 AM till 6:00 PM (KST) 7 days in week and by phone during the evenings since 2005. KVERT analyses daily satellite imagery (since 2002 till now); information from remote scientific observation stations; real-time seismic data for 11 Kamchatkan volcanoes (data from the Kamchatkan Branch of Geophysical Survey RAS); and other information to monitor activity at Kamchatkan and Northern Kuriles Volcanoes.
