Continuous volcanic ash emissions from Sheveluch volcano reach 7 600 m (25 000 feet) a.s.l., Russia

Volcanic ash from Sheveluch in Russia was observed at 7 600 m (25 000 feet) above sea level at 05:20 UTC on March 28, 2026. The advisory was issued by the Tokyo VAAC at 06:00 UTC.

Satellite imagery from Himawari-9 confirmed continuous ash emissions at an altitude of 7 600 m (25 000 feet). Some portions of the ash cloud were obscured by meteorological clouds. The ash was moving southeast at approximately 37 km/h (23 mph). The forecast for +12 hours indicated that ash could be as high as 7 900 m (26 000 feet). No Aviation Color Code was stated in this advisory.

According to the Smithsonian / USGS Weekly Volcanic Activity Report, Sheveluch exhibited ongoing eruptive activity between March 11 and March 18, 2026, with explosions generating ash plumes up to 11 000 m (36 100 feet) above sea level and drifting considerable distances east and northeast. The Aviation Color Code was Orange during this period, indicating ongoing hazards for aviation.

Sheveluch is a large stratovolcano located in the northern part of the Kamchatka Peninsula, Russia. The volcano is known for frequent explosive eruptions, producing ash plumes, pyroclastic flows, and lava domes. Ashfall and pyroclastic flows can threaten nearby settlements such as Klyuchi, about 50 km (31 miles) to the south. The primary hazards are volcanic ash, pyroclastic density currents, and lahar activity, posing risks to both local communities and air traffic in the region.
