Kamchatka and the Northern Kuriles volcanoes: Erupting or Restless

KVERT/Volcano Observatory Notification to Aviation

VONA/KVERT WEEKLY INFORMATION RELEASE 31-2015
Kamchatkan and Northern Kuriles Volcanic Activity

July 30, 2015, 23:08 UTC (July 31, 2015, 11:08 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

NORTHERN KURILES
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 #300270)
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 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 the northern its flank), fumarolic activity and an incandescence of the dome blocks and hot avalanches accompanies this process. Satellite data showed a thermal anomaly over the lava dome all week.

KARYMSKY VOLCANO (CAVW #300130)
54.05 N, 159.44 E; Elevation 4874 ft (1486 m)
Aviation Color Code is ORANGE


Moderate eruptive 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.

Moderate explosive eruption of the volcano continues. According to visual data by pilots of helicopter Mi-8 (AMC data), explosions sent ash up to 4 km a.s.l. on July 28, ash plumes drifted to the north of the volcano. Satellite data by KVERT and Tokyo VAAC showed: ash plumes extended about 65 km to the east and north-west of the volcano on July 25 and 27-30. A thermal anomaly was noting over the volcano all week.

BEZYMIANNY VOLCANO (CAVW #300250)
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.

According to visual data, moderate gas-steam activity of the volcano was noting or the volcano was obscured by clouds last week. Satellite data showed a thermal anomaly over the volcano on July 27-30.

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.
