SUMMARY OF AVIATION COLOR CODES:

 

KAMCHATKA:

SHEVELUCH, KLYUCHEVSKOY and KARYMSKY: ORANGE

GORELY and BEZYMIANNY: YELLOW

TOLBACHIK PLOSKY, KORYAKSKY, AVACHINSKY, MUTNOVSKY and KIZIMEN: GREEN

 

NORTHERN KURILES:

EBEKO: YELLOW

CHIKURACHKI and ALAID: GREEN

 

KLYUCHEVSKOY VOLCANO: 56o03'N, 160o39'E; Elevation 4,750 m

AVIATION COLOR CODE IS ORANGE

 

Explosive-effusive eruption of the volcano continues. Ash explosions >7.0 km (>23,000 ft) ASL could occur at any time. The activity of the volcano could affect international and low-flying aircraft.

 

Seismicity of the volcano was above background levels all week. According to visual data, moderate gas-steam activity of the volcano were observing on Jule 2-4. Sometimes ash columns rose up to 5.3 km (17,400 ft ) ASL. Clouds obscured the volcano in the other days. According to satellite data, a big thermal anomaly was registering over the volcano all week. A gas-steam plume containing ash extended about 76 km to the south from the volcano on July 02.

SHEVELUCH VOLCANO: 56o39'N, 161o21'E; Elevation 3,283 m, the dome elevation ~2,500 m

AVIATION COLOR CODE IS ORANGE

 

Explosive-extrusive eruption of the volcano continues.  Ash explosions   >10 km (>32,800 ft) ASL could occur at any time. The activity of the volcano could affect international and low-flying aircraft.

 

Seismicity was above background levels all week. According to seismic data, possibly ash plumes rose up to 7 km (22,900 ft ) ASL on Jule 2-6. According to visual data, ash fall was observed on removal 30 km at volcano on July 05. Ash plumes from hot avalanches rose up to 4 km (13,100 ft ) ASL on July 05, and strong fumarolic activity were observed in the other days. According to satellite data, a thermal anomaly was registering over the lava dome all week. Ash plume extended about 20 km ( 65,600 ft ) to the south from the volcano on July 07.

KARYMSKY VOLCANO: 54o03'N, 159o27'E; Elevation 1,486 m

AVIATION COLOR CODE IS ORANGE

 

Explosive activity of the volcano continues. Ash explosions > 6.0 km (or 19,700 ft) ASL could occur at any time. Activity of the volcano could affect low-flying aircraft.

 

Seismic activity of the volcano was above background levels all week. According to seismic data, possibly ash plumes rose up to  2 km (6,500 ft) ASL on Jule 05. According to satellite data, a thermal anomaly was registering over the volcano five days. Clouds obscured the volcano in the other days of week. Ash lume extended about 20 km  (65,600 ft)to the south from the volcano on July 07.

GORELY VOLCANO: 52o33'N, 158o02'E; Elevation 1,828 m

AVIATION COLOR CODE IS YELLOW

 

Activity of the volcano is increasing. Probably an eruption of Gorely is preparing. Aerosol plumes from the volcano could affect low-flying aircraft.

 

Seismicity of the volcano was above background levels all week. Amplitude of volcanic tremor  remains on levels 1.7-1.8 mkm/s and at increasing up to 2 mkm/s on Jule 6. Gas-steam activity of the volcano was observing on  Jule 04. According to satellite data, the thermal anomaly over the volcano was registering on Jule 3. A gas-steam plume extended about 30 ( 98,400 ft ) km to the south from the volcano on Jule 8. Clouds obscured the volcano in the other days.

BEZYMIANNY VOLCANO: 55o58'N, 160o36'E; Elevation 2,882 m

AVIATION COLOR CODE IS YELLOW

 

Grows of the lava dome of the volcano continues and aerosol plumes could affect low-flying aircraft.

 

Strong volcanic activity of Klyuchevskoy volcano obscured seismic data of Bezymianny all week. According to visual data, clouds obscured the volcano all week. According to satellite data, a small thermal anomaly was registering over the dome on Jule 6-8.

EBEKO VOLCANO: 50o41'N, 156o01'E Elevation 1,156 m

AVIATION COLOR CODE IS YELLOW

 

Activity of the volcano increases. Ebeko volcano is not monitored with seismic instruments. KVERT has satellite monitoring and occasional visual messages about this volcano. The danger of sudden ash explosions as high as 3 km (9,840 ft.) ASL as well as ash falls at Severo-Kurilsk, exists.

 

According to the data by local observers at Severo-Kurilsk, activity on the volcano increases. Ash explosions at the volcano began to occur from 03:53 UTC on July 02. A height of ash column was about 1.8 km ASL. Ash plume extends to the south-south-east - to Severo-Kurilsk. KVERT continues to monitor the volcano.

The Kamchatkan Volcanic Eruption Response Team (KVERT) is a non-commercial cooperative program of the Alaska Volcano Observatory (AVO, USA), the Institute of Volcanology and Seismology (IVS) FED RAS and the Kamchatkan Branch of Geophysical Survey (KB GS) RAS (Russia ). KVERT staff is vailable in the office from 8:30 AM till 6:00 PM (KST or KDT) and by phone during the evenings. KVERT uses daily satellite imagery, information from remote scientific observation stations, real-time seismic data for 10 volcanoes, and other information to monitor activity at Kamchatkan and Northern Kuriles Volcanoes.
