Continuous volcanic ash emissions at Sheveluch volcano reach 8 200 m (27 000 feet) a.s.l., Russia

Volcanic ash from Sheveluch in Russia was observed at 8 200 m (27 000 feet) above sea level at 11:20 UTC on March 29, 2026. The advisory was issued by the Tokyo VAAC at 12:00 UTC.

According to the advisory, ash was continuously observed in satellite imagery. The altitude of the ash cloud was updated to flight level 270, which corresponds to 8 200 m (27 000 feet). The ash cloud was moving east at 56 km/h (35 mph). No Aviation Color Code was stated in this advisory.

According to the most recent Smithsonian / USGS Weekly Volcanic Activity Report, Sheveluch volcano has exhibited continuing eruptive activity, with explosions detected between March 11 and 18, 2026. Ash plumes during this time rose as high as 11 000 m (36 100 feet) above sea level and drifted significant distances east and northeast. The Aviation Color Code at that time was Orange.

Sheveluch is a large stratovolcano located on the Kamchatka Peninsula in Russia. The volcano is notable for frequent explosive eruptions which can produce high ash plumes, pyroclastic flows, and lava domes. Hazards include ashfall, pyroclastic flows, and dome collapse events that can threaten communities such as Klyuchi, situated about 50 km (31 miles) to the south. Ash plumes from Sheveluch often affect air travel across the North Pacific region.
