7.8-Magnitude Quake Strikes Russia’s Kamchatka, Tsunami Alerts Issued

  • 19/09/2025

A powerful magnitude 7.8 earthquake struck Russia’s Kamchatka Peninsula on September 19, identified by the US Geological Survey as an aftershock of July’s record-breaking 8.8 quake—the strongest in the region in more than a century. The tremor, caused by shallow reverse faulting at a depth of just 10 kilometers, was followed by several aftershocks, including one measuring 5.8. Russia’s Emergencies Ministry registered it at 7.2.

Tsunami warnings were promptly issued across Kamchatka and extended to the Kuril Islands, with waves reaching up to 62 centimeters on the eastern coast. The US Pacific Tsunami Warning Center briefly issued an advisory for parts of Alaska, but later lifted it. Authorities confirmed that emergency services were on high alert, conducting inspections of public facilities and homes to ensure safety. Governor Vladimir Solodov praised residents for remaining calm and prepared amid the repeated seismic activity.

Videos posted by locals showed swaying lights, rattling furniture, and car alarms triggered by the tremors. Situated along the volatile Pacific “Ring of Fire,” Kamchatka is no stranger to strong seismic events, having recorded multiple quakes above magnitude 7.0 in the past week alone. July’s catastrophic 8.8 earthquake remains the most destructive in recent history, sparking a Pacific-wide tsunami and flooding in a coastal town.
