An 8.8-magnitude earthquake struck Russia’s Kamchatka Peninsula near Avacha Bay, raising significant safety concerns due to the proximity of Russian nuclear submarine bases. The quake’s epicenter was just 75 miles from Avacha Bay, home to the Rybachiy submarine base, which hosts advanced nuclear-powered Yasen-class cruise missile submarines and Borei-class ballistic missile submarines—key components of Russia’s strategic nuclear deterrent. While Russian authorities report no major damage or injuries, satellite imagery and local footage show collapsed buildings, damaged ports, and flooded infrastructure, prompting military analysts to scrutinize the situation closely. Experts are particularly worried about potential unseen damage to submarines, especially those undergoing maintenance with exposed hatches, as seismic activity and the resulting tsunami could have compromised their safety and operational readiness. Although a retired Russian Navy officer emphasized the robustness of these bases, built to withstand nuclear strikes, the combination of seismic waves, tsunami risks, and sensitive nuclear equipment has heightened concerns.
