Russia’s far east nuclear submarine base appears to have been damaged by the tsunami that swept the country’s Pacific coast on Wednesday, according to satellite imagery obtained by The Telegraph.

A volcano in eastern Russia erupted for the first time in 475 years, prompting a tsunami warning. The Krasheninnikov volcano in Kamchatka became active days after one of the strongest earthquakes ever recorded hit the region.

Tsunami alerts were issued for Alaska and Hawaii on Tuesday after a major, 8.8 magnitude earthquake struck off the coast of Russia, according to officials.
