An extrusive-effusive eruption at Bezymianny volcano in Kamchatka, Russia, intensified on April 11, 2025, producing pyroclastic flows on the eastern slopes and ash plumes reaching 3–4 km (9 800–13 100 feet) above sea level. Current data suggests the volcano is preparing for a strong explosive eruption.
An eruption at Bezymianny volcano in Kamchatka, Russia, sent ash up to 4 km (13 123 feet) a.s.l. and triggered seismic activity at 10:20 LT (00:20 UTC) on February 1, 2025. KVERT raised the Aviation Color Code to Orange on January 31, marking the first upgrade in three months since October 4, 2024.
Heavy ash from Shiveluch volcano coated over 7 000 km² (2 700 mi²) of land east of the volcano, creating hazardous conditions in populated areas like Ust-Kamchatsk and Klyuchi. The ash spread up to 430 km (270 miles) away, disrupting regional flights and prompting authorities to issue the highest aviation alert.
A strong explosive eruption began at Russia’s Sheveluch volcano at 09:20 UTC on November 7, 2024. The eruption produced significant volcanic ash emissions, with an ash plume reaching altitudes of 11 km (36 000 feet) above sea level. The ash cloud is drifting east-northeast, posing a threat to aviation.
