Five volcanoes on the Kamchatka Peninsula are either erupting or showing signs of impending eruption. In this image a thick plume of ash streams from a lava dome on Shiveluch Volcano.
Aviation Color Code: Orange
Volcano Location: 56°39'N, 161°21'E
Summit Elevation (feet/meters): 8202 ft/2.500 m the dome elevation
Height of ash plume (feet/km) ASL and how determined: 9843 ft/ 3.0 km- Visual
Distance of ash plume from the volcano (mi/km): 55.94 mi/90 km
Direction of ash plume or ash cloud drift from the volcano: South-East
Duration of eruption (or indicate eruption is continuing): eruption is continuing
Remarks: Strong ash storm (very strong wind) is observing at the volcano Sheveluch. No explosions. Ash plume is extending about 90 km to the south-east from the volcano.
The 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, probably ash plumes rose up to 19,680 ft (6.0 km) ASL on August 01 and up to 9,840 ft (3.0 km) ASL on August 02. According to visual data, ash plumes rose up to 22,960 ft (7.0 km) on August 01, and up to 13,120 ft (4.0 km) on August 02. An ash plume extending about 0.6 mi (24 km) to the south from the volcano was noted on satellite image on August 01. A strong dust storm was observed at the volcano on August 03; dust plume extending about 99 mi (160 km) to the south-east from the volcano was detected on satellite images. A thermal anomaly was registering over the lava dome on July 28 and 30, and August 01-03.
The eruption of the volcano Kizimen 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. Weak volcanic tremor continues to registering all week. According to video data, moderate fumarole activity was observing all week; sometimes a gas-steam plume rose up to 14,760 ft (4.5 km) ASL. The lava flow continues to moving on the eastern flank of the volcano. A big bright thermal anomaly was registering over the volcano all week at satellite images.
Activity of the volcano Karymsky could affect low-flying aircraft. Moderate seismic activity of the volcano continues; according to seismic data, possible ash plumes rose up to 18,040 ft (5.5 km) ASL all week. A thermal anomaly was registering over the volcano on July 30 - August 03; the volcano was obscured by clouds on the other days of the week. (KVERT)
