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.
