A massive 8.8-magnitude earthquake struck off Russia’s eastern coast on July 30, prompting widespread tsunami alerts. Satellite images cited by The New York Times reveal damage to a floating nuclear submarine base at Rybachiy in the Kamchatka Peninsula. Though a section appears to have shifted, major visible destruction was not confirmed. The quake also triggered a rare volcanic eruption and caused a tsunami that hit Russia’s Severo-Kurilsk port. Despite structural damage, no casualties have been reported so far.
