Shallow M6.0 earthquake hits southeast of Petropavlovsk-Kamchatsky, Russia on November 4, 2025
A shallow M6.0 earthquake was recorded at 23:28 UTC on November 4, 2025, approximately 143 km (89 miles) southeast of Petropavlovsk-Kamchatsky, Russia. According to the USGS, the quake struck at a depth of 14.6 km (9.1 miles) with its epicenter located at 52.1°N, 160.1°E.
This region lies in the far eastern Kamchatka Peninsula, an area known for significant seismic and volcanic activity. Petropavlovsk-Kamchatsky is the nearest major city, with a population exceeding 300,000, but the epicenter’s offshore location places it away from densely inhabited areas.
Due to its proximity to the Pacific coast and the Avacha Bay area, the zone hosts key infrastructure such as international and regional airports, seaports, and vital transport routes supporting both industry and fisheries.
There is no tsunami threat associated with this earthquake, based on its offshore location and available data.
USGS issued a green alert for this event, indicating a low likelihood of casualties or damage. The maximum estimated shaking intensity is IV. The significance index is 554 (on a scale that runs through 1 000), based on magnitude, felt reports, and estimated impact.
The Kamchatka Peninsula is tectonically active, situated near the convergent boundary between the Pacific Plate and the North American Plate, and forms part of the Pacific Ring of Fire.
