VONA/KVERT WEEKLY INFORMATION RELEASE 27-2016
Kamchatkan and Northern Kuriles Volcanic Activity

July 07, 2016, 23:02 UTC (July 08, 2016, 11:02 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
KLYUCHEVSKOY, SHEVELUCH: ORANGE

AVACHINSKY, DIKY GREBEN, GAMCHEN, GORELY, ICHINSKY, ILIINSKY, KAMBALNY, KHANGAR, KHODUTKA, KIKHPINYCH, KIZIMEN, KOMAROV, KORYAKSKY, KOSHELEV, KRASHENINNIKOV, KRONOTSKY, KSUDACH, MALY SEMYACHIK, MUTNOVSKY, OPALA, PLOSKY TOLBACHIK, TAUNSHITS, USHKOVSKY, VYSOKY, ZHELTOVSKY, ZHUPANOVSKY: GREEN

NORTHERN KURILES

CHIKURACHKI, EBEKO, FUSS PEAK, KARPINSKY, TATARINOV: 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 reveal in the northern its part), strong fumarole activity, ash explosions, hot avalanches and an incandescence of the dome blocks and hot avalanches accompany this process. Satellite data by KVERT showed a thermal anomaly over the lava dome all week. 04 July, the plume of resuspended ash blowing from the vicinity of Sheveluch area drifted for about 65 km to the south-east from the volcano.

KLYUCHEVSKOY VOLCANO (CAVW #300260)
56.06 N, 160.64 E; Elevation 15580 ft (4750 m)
Aviation Color Code is ORANGE


Explosive-effusive eruption of the volcano continues. Ash explosions up to 19,700-26,240 ft (6-8 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.

Explosive-effusive eruption of the volcano continues: there are bursts of volcanic bombs to 200-300 m above the summit crater and up to 50 m above the cinder cone into Apakhonchich chute, and strong gas-steam activity of two volcanic centers with emission of different amounts of ash, the effusing of lava flows along Apakhonchich chute at the south-eastern flank of the volcano. According to the video data, an intensification of the eruption was noted on 06 July: strong explosions sent ash up to 7.5 km a.s.l. According to satellite data by KVERT, a large bright thermal anomaly in the area of the volcano was observed all week, ash plumes drifted for about 350 km to the southwest, south and southeast from the volcano on 02-05 July; and dense ash plumes drifted for about 400 km to the southeast and east from the volcano on 06-07 July.

ALAID VOLCANO (CAVW #290390)
50.86 N, 155.56 E; Elevation 7672 ft (2339 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. Ongoing activity could affect low-flying aircraft.

A moderate explosive-effusive eruption of the volcano continues: Strombolian activity of the new cinder cone in the summit crater of the volcano and a lava flow effusing on the southwestern flank of Alaid. According to satellite data by KVERT, a thermal anomaly over the volcano was noted all week, on July 03-04 ash plumes drifted for about 150 km to the south-west from the volcano.

BEZYMIANNY VOLCANO (CAVW #300250)
55.97 N, 160.6 E; Elevation 9453 ft (2882 m)
Aviation Color Code is YELLOW


A moderate gas-steam activity of the volcano continues. Ongoing activity could affect low-flying aircraft.

A moderate gas-steam activity of the volcano continues. Satellite data by KVERT showed a thermal anomaly over the volcano on 04 and 06 July, the volcano was quiet or obscured by clouds in the other days of week.

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


A moderate gas-steam activity of the volcano continues, but 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 gas-steam activity of the volcano continues. Satellite data by KVERT showed a thermal anomaly over the volcano on 04 July, 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 produces daily satellite monitoring (since 2002 till now); analyses information from remote scientific observation stations and seismic data for volcanoes: Alaid, Avachinsky, Bezymianny, Gorely, Karymsky, Kizimen, Klyuchevskoy, Koryaksky, Mutnovsky, Plosky Tolbachik, Sheveluch, Ushkovsky, Zhupanovsky (from the Kamchatkan Branch of Geophysical Survey RAS); and other information to monitor activity at Kamchatkan and Northern Kuriles Volcanoes.

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.

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]
