Key facts
- Shiveluch volcano on Kamchatka Peninsula erupted, sending ash 10 km high.
- Red-level aviation alerts issued for the region and nearby areas.
Russia's Shiveluch volcano erupted, sending ash 10 km high and triggering red-level aviation alerts. A larger explosion up to 12 km is possible. This is the second eruption this week.
Volcanic ash plumes can disrupt air travel by damaging aircraft engines, leading to flight cancellations and rerouting, impacting regional and potentially international air traffic. The event also highlights the ongoing seismic activity in a geologically active region.
The Shiveluch volcano on Russia's Kamchatka Peninsula has erupted, sending a massive ash plume 10 kilometers into the sky and triggering red-level aviation alerts for the area and surrounding regions. The ash cloud from Saturday's eruption stretched approximately 50 kilometers east toward the Bering Sea. The Volcanology and Seismology Institute warned that a more powerful explosion, potentially sending ash up to 12 kilometers high, could occur at any time. This marks the second eruption of Shiveluch in a week, following an event on Thursday that produced an ash column reaching eight kilometers. Shiveluch is known as one of Kamchatka's largest and most active volcanoes. The previous red-level alert for Shiveluch was issued in 2024 for an eruption that sent ash eight kilometers high.
