Information of Kamchatkan Volcanic Eruption Response Team (KVERT)
VONA/KVERT WEEKLY INFORMATION RELEASE 49-2013
Kamchatkan and Northern Kuriles Volcanic Activity December 05, 2013, 22:29 UTC (December 06, 2013, 10:29 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: http:www.emsd.ru): SHEVELUCH, KARYMSKY: ORANGE KLYUCHEVSKOY, BEZYMIANNY, PLOSKY TOLBACHIK, KIZIMEN, GORELY: YELLOW USHKOVSKY, KORYAKSKY, AVACHINSKY, MUTNOVSKY: GREEN No seismic data: ICHINSKY, VYSOKY, KOMAROV, GAMCHEN, KHANGAR, KRONOTSKY, KRASHENINNIKOV, TAUNSHITS, KIKHPINYCH, MALY SEMYACHIK, ZHUPANOVSKY, OPALA, KHODUTKA, KSUDACH, ZHELTOVSKY, ILIINSKY, DIKY GREBEN, KOSHELEV, KAMBALNY: GREEN NORTHERN KURILES No seismic data: ALAID, 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. Eruption of the volcano continues: a new lava dome continues to extrude on the north-western part of the old lava dome, moderate ash explosions up to 13,100-16,400 ft (4-5 km) a.s.l., fumarolic activity and incandescence of the dome summit and hot avalanches accompanies this process. Satellite data showed a thermal anomaly over the lava dome. http://www.kscnet.ru/ivs/kvert/volcanoes/Sheveluch/index_eng.php 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. Moderate seismic activity of the volcano continues. Strombolian and Vulcanian activity of the volcano was observed on December 02-03. Satellite data showed a bright thermal anomaly over the volcano all week. http://www.kscnet.ru/ivs/kvert/volcanoes/Karymsky/index_eng.php KLYUCHEVSKOY VOLCANO (CAVW #1000-26-) 56.06 N, 160.64 E; Elevation 15580 ft (4750 m) Aviation Color Code is YELLOW Eruption of the volcano continues. Ash explosions up to 32,800 ft (10.0 km) a.s.l. could occur at any time. The activity of the volcano could affect international and low-flying aircraft. Moderate seismic activity of the volcano continues. Video data showed strong and moderate gas-steam activity of the volcano. Satellite data showed a very weak thermal anomaly over the volcano summit all week. http://www.kscnet.ru/ivs/kvert/volcanoes/Klyuchevskoy/index_eng.php BEZYMIANNY VOLCANO (CAVW #1000-25-) 55.97 N, 160.6 E; Elevation 9453 ft (2882 m) Aviation Color Code is YELLOW Moderate activity of the volcano continues. Ongoing activity could affect low-flying aircraft. Seismicity of the volcano was weak. Video data showed a moderate gas-steam activity of the volcano. Satellite data showed a weak thermal anomaly over the volcano all week. http://www.kscnet.ru/ivs/kvert/volcanoes/Bezymianny/index_eng.php PLOSKY TOLBACHIK VOLCANO (CAVW #1000-24-) 55.83 N, 160.39 E; Elevation 10119 ft (3085 m) Aviation Color Code is YELLOW Moderate activity of the volcano continues. Ongoing activity could affect low-flying aircraft. A weak seismic activity of the volcano continues. A thermal anomaly was observed on satellite images at the northern area of Tolbachinsky Dol all week. http://www.kscnet.ru/ivs/kvert/volcanoes/Plosky Tolbachik/index_eng.php KIZIMEN VOLCANO (CAVW #1000-23-) 55.13 N, 160.32 E; Elevation 8151 ft (2485 m) Aviation Color Code is YELLOW Extrusive eruption of the volcano gradually finishing. Activity of the volcano could affect low-flying aircraft. A weak seismic activity of the volcano continues. Video data showed moderate gas-steam activity of the volcano. Satellite data showed a very weak thermal anomaly over the volcano all week. http://www.kscnet.ru/ivs/kvert/volcanoes/Kizimen/index_eng.php 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. Weak gas-steam activity of the volcano was observing. Satellite data showed clouds obscured the volcano all week. http://www.kscnet.ru/ivs/kvert/volcanoes/Gorely/index_eng.php IF YOU HAVE ANY QUESTIONS OR CONCERNS, PLEASE CONTACT: Dr. Olga A. Girina, Head of KVERT, IVS FEB RAS E-mail: girina@kscnet.ru Tel.: +74152297890 Tel. Duty scientist: +79622825253 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 Color 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. |
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. |
