Overview

• Satellite and synthetic-aperture radar imagery from Planet Labs confirm that only a floating pier at the Rybachiy base detached from its anchor point.
• No nuclear submarines were docked at the pier during the July 31 tremor, and analysis shows no other significant damage across the facility.
• International nuclear monitoring agencies report that radiation levels around the base remained within normal limits following the seismic event.
• Russia’s Defense Ministry has not issued any public statements on the condition of the Pacific Fleet’s strategic hub.
• Specialists caution that ongoing seismic and volcanic activity in the Pacific Ring of Fire could pose future risks to the Cold War-era installation.
