VONA/KVERT WEEKLY INFORMATION RELEASE 13-2013
Kamchatkan and Northern Kuriles Volcanic Activity

March 28, 2013, 22:11 UTC (March 29, 2013, 10:11 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:

SHEVELUCH VOLCANO (CAVW #1000-27-)
56.64 N, 161.32 E; Elevation 10768 ft (3283 m), the dome elevation ~8200 ft (2500 m)
Aviation Color Code is ORANGE


Explosive-extrusive-effusive eruption of the volcano continues. Ash explosions up to 23,800 ft (10 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.

Eruption of the volcano continues. According to visual and satellite data, a viscous lava flow continues to effuse on the eastern flank of the lava dome, strong and moderate fumarolic activity and incandescence of the dome summit and hot avalanches accompanies this process. Satellite data showed a thermal anomaly over the lava dome all week.

PLOSKY TOLBACHIK VOLCANO (CAVW #1000-24-)
55.83 N, 160.39 E; Elevation 10119 ft (3085 m)
Aviation Color Code is ORANGE


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

Effusion of lava flows continues from the Southern fissure at Tolbachinsky Dol. Very fluid lava is moving to the southern, eastern and western slopes of Tolbachinsky Dol. Cinder cones continue to grow on the Southern fissure. Gas-steam plumes with ash rose up to 11,500 ft (3.5 km) a.s.l. and extended to different directions of Tolbachinsky Dol last week. A big thermal anomaly was noting at satellite images in the northern area of Tolbachinsky Dol all week.

KIZIMEN VOLCANO (CAVW #1000-23-)
55.13 N, 160.32 E; Elevation 8151 ft (2485 m)
Aviation Color Code is ORANGE


Extrusive-effusive eruption of the volcano continues. Ash plumes up to 19,700 ft (6 km) a.s.l. could occur at any time. Activity of the volcano could affect low-flying aircraft.

Moderate seismic activity of the volcano continues. Video and satellite data showed a growth of an extrusion at the volcano summit continues. Incandescence of the volcano summit, hot avalanches on the western and eastern volcanic flanks and strong gas-steam activity accompany this process. Satellite data showed a thermal anomaly over the volcano all week.

KARYMSKY VOLCANO (CAVW #1000-13-)
54.05 N, 159.44 E; Elevation 4874 ft (1486 m)
Aviation Color Code is ORANGE


Moderate explosive eruption of the volcano continues. Ash explosions up to 19,700 ft (6 km) a.s.l. could occur at any time. Activity of the volcano could affect low-flying aircraft.

Weak and moderate seismic activity of the volcano was detected on March 20-21; there was not seismic data by technical reasons in the other days of week. Satellite data showed the volcano was obscured by clouds.

BEZYMIANNY VOLCANO (CAVW #1000-25-)
55.97 N, 160.6 E; Elevation 9453 ft (2882 m)
Aviation Color Code is YELLOW


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

Strong seismicity at Tolbachinsky Dol obscured seismicity of Bezymianny. The viscous lava flow continues to effusing on the lava dome flank. Weak and moderate gas-steam activity accompany this processes. Satellite data shows a weak thermal anomaly over the volcano on March 25 and 27; clouds obscured the volcano on the other days of week.

GORELY VOLCANO (CAVW #1000-07-)
52.56 N, 158.03 E; Elevation 5996 ft (1828 m)
Aviation Color Code is YELLOW


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

Moderate seismic activity of the volcano continues. Video data showed a moderate and strong gas-steam activity of the volcano or it was obscured by clouds.

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.

Aviation Colour Codes

GREEN

Volcano is in normal, non-eruptive state

   or, after a change from a higher level:

Volcanic activity considered to have ceased, and volcano reverted to its normal, non-eruptive state.

YELLOW

Volcano is experiencing signs of elevated unrest above known background levels.    

 or, after a change from higher level:

Volcanic activity has decreased significantly but continues to be closely monitored for possible renewed increase.

ORANGE

Volcano is exhibiting heightened unrest with increased likelihood of eruption.

   or,

Volcanic eruption is underway with no or minor ash emission.
[specify ash-plume height if possible]

RED

Eruption is forecast to be imminent with significant emission of ash into the atmosphere likely.

  or,

Eruption is underway with significant emission of ash into the atmosphere.
[specify ash-plume height if possible]
