Volcanic ash from Sheveluch volcano observed at 9 800 m (32 000 feet) a.s.l., Russia

Volcanic ash from Sheveluch in Russia was observed at 9 800 m (32 000 feet) above sea level at 05:20 UTC on March 29, 2026. The advisory was issued by the Tokyo VAAC at 06:00 UTC.

According to the VAAC advisory, the ash cloud height was updated to FL320, equivalent to 9 800 m (32 000 feet), based on satellite data from Himawari-9. The ash was moving east at 56 km/h (35 mph). No Aviation Color Code was stated in this advisory.

The Smithsonian’s Global Volcanism Program notes that Sheveluch exhibited ongoing eruptive activity during the week of March 12–18, 2026. Explosions generated ash plumes rising up to 11 000 m (36 100 feet) above sea level, with plumes drifting for thousands of kilometers east and northeast. The Aviation Color Code at that time was Orange.

Sheveluch is a large stratovolcano located in Kamchatka, Russia. It is known for explosive eruptions, significant ashfall, pyroclastic flows, and large lava domes. The nearest population center at risk is the town of Klyuchi, located approximately 50 km (31 miles) south of the volcano.
