The Shiveluch volcano in Russia's Kamchatka Peninsula erupted, sending ash clouds up to 5 kilometers high, shortly after a powerful 7.0 magnitude earthquake struck off the coast.

This earthquake occurred at a depth of 6 kilometers under the sea bed, with its epicenter located 108 kilometers southeast of Petropavlovsk-Kamchatsky.

Residents of Petropavlovsk-Kamchatsky reported experiencing some of the strongest shaking felt in a long time, although there have been no immediate reports of injuries.

Despite the aviation alert due to the ash cloud, there have been no reported impacts on commercial flights or airport infrastructure.

A video from the Institute of Volcanology and Seismology showed the ash cloud from Shiveluch extending over 490 kilometers.

Volcanologists from the Russian Academy of Sciences have warned that further tremors could lead to a potential second earthquake with a magnitude close to 9.0 within the next 24 hours.

In addition to Shiveluch, the Ebeko volcano on the Kuril Islands also erupted, releasing ash up to 2.5 kilometers high, although it remains unclear if this was related to the earthquake.

Historically, Kamchatka has experienced significant seismic activity, including a magnitude 9.0 earthquake in 1952 that caused damage but no fatalities.

Overall, despite the volcanic activity and earthquake, there have been no immediate reports of injuries or damage.
