Kamchatkan and Northern Kuriles Volcanic Activity

August 28, 2014, 22:36 UTC (August 29, 2014, 10:36 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:

Real-time seismic data (from the Kamchatkan Branch of Geophysical Survey RAS: http:www.emsd.ru), ALAID: GREEN

No seismic data:
EBEKO, CHIKURACHKI, TATARINOV, FUSS PEAK, KARPINSKY: GREEN


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 32,800 ft (10 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.

A growth of the lava dome continues (a viscous lava flow effuse on southeastern flank), moderate ash explosions, fumarolic activity and incandescence of the dome summit and hot avalanches accompanies this process. Satellite data showed a thermal anomaly over the lava dome on August 24-28, the volcano was obscured by clouds in the other days of week.

ZHUPANOVSKY VOLCANO (CAVW #1000-12-)
53.59 N, 159.15 E; Elevation 9702 ft (2958 m)
Aviation Color Code is ORANGE


Moderate explosive eruption of the volcano continues. Ash explosions up to 26,250 ft (8 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.

Moderate explosive eruption of the volcano continues. According to visual and video data, an ash plume from the volcano was observed over the pass between Avachinsky and Koryaksky volcanoes on August 28. Satellite data showed ash plumes rose up to 11,500-13,100 ft (3.5-4 km) a.s.l. and extended about 50 mi (80 km) to the south-west of the volcano on August 28; a thermal anomaly over the volcano on August 25 and 27; the volcano was quiet or obscured by clouds in the other days of week.

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


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

A weak seismic activity of the volcano was registering. According to video data, a moderate gas-steam activity of the volcano was observing on August 24-28, the volcano was obscured by clouds in the other days of week. Satellite data showed a thermal anomaly over the volcano on August 24-25 and 27-28, the volcano was obscured by clouds in the other days of week.

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


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

A moderate and weak seismic activity of the volcano was registering. Satellite data showed a thermal anomaly over the volcano on August 27, the volcano was quiet or obscured by clouds in the other days of week.

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.

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]
