Explosive-extrusive eruptions of the Kamchatkan volcanoes continues

One of the major volcanoes in the Kamchatka Peninsula, the Shiveluch, has belched out ash to the elevation of 10 kilometers above sea level. A total of two series of local seismic events lasting from 40 minutes to 60 minutes have been registered at the volcano. It might have been accompanied by the exuding of ash to the elevations of 6.7 kilometers and 10 kilometers respectively. The ash columns could not be observed visually since the summit of the volcano is overcast with clouds. There has been no fallout of volcanic ash in the nearby population centers, including the town of Klyuchi, which is located some 30 kilometers away from the Shiveluch’s foothills. A senior researcher at the Geophysical Service said the trail of ash had shifted northwards from the volcano where there are no townships of villages.(…)

SHEVELUCH VOLCANO (1000-27)
AVIATION COLOR CODE IS ORANGE

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

Moderate seismic activity of the volcano continues. According to seismic data, ash plumes rose up to 32,800 ft (10.0 km) ASL on June 15. According to visual data, moderate gas-steam activity of the volcano was observing on June 10 and 12; clouds obscured the volcano on the other days of week. According to satellite data, a gas-steam plume containing small amount of ash extended about 16 mi (26 km) to the north-west from the volcano on June 10. A thermal anomaly was registered over the lava dome on June 10 and 12-13; clouds obscured the volcano on the other days.


KIZIMEN VOLCANO (1000-23)
CURRENT AVIATION COLOR CODE IS ORANGE

Eruption of the volcano continues. Strong ash explosions up to 32,800 ft (10 km) ASL could occur at any time. Ongoing activity could affect international and low-flying aircraft.

Seismic activity was above background levels all week. Strong volcanic tremor continues to registering all week. According to seismic data, possibly ash plumes rose up to 19,400 ft (5.9 km) ASL on June 11-15. According to visual data from Klyuchevskoy volcano slope, a strong directed burst from Kizimen was observing on June 11-12. Ash plumes extending about 471 mi (about 760 km) to the eastern directions from the volcano were noted on June 11-13. A bright thermal anomaly was registering over the volcano on June 10-14 at satellite images; on the other days it was obscured by clouds.

History of Kizimen eruptions is unknown. We have incomplete data about only one eruption in 1928-1929 which were likely moderate explosive (or explosive-effusive) events. Tephrachronological data point out several catastrophic eruptions in evolution of this volcano.

KARYMSKY VOLCANO (1000-13)
AVIATION COLOR CODE IS ORANGE

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

Moderate seismic activity of the volcano continues, possible ash plumes rose up to 18,000 ft (5.5 km) ASL all week. A thermal anomaly was registering over the volcano on June 10-14. An ash plume extending about 56 mi (90 km) to the north-east was noted at satellite images on June 14.
