The record gives no deaths, injuries or damage for this earthquake.

Tectonic setting

Why earthquakes happen here, from the USGS tectonic summary.

This September 13, 2025, M7.4 earthquake that occurred east of Petropavlovsk-Kamchatsky, Russia is an aftershock of the M8.8 Kamchatka Peninsula earthquake that struck on July 29, 2025. The aftershock resulted from shallow reverse faulting. As of its occurrence, it is the largest aftershock recorded following the M8.8 mainshock. At the earthquake’s location, the Pacific Plate is moving west-northwest relative to the North American Plate at a rate of approximately 80 mm/year. The earthquake’s location and faulting mechanism are consistent with faulting along the subduction zone plate interface of the Kuril-Kamchatka arc.

Although earthquakes are often represented as points on maps, events of this magnitude are better described as slip across a broad fault area. Reverse faulting earthquakes of this size typically involve rupture dimensions of approximately 70 km in length and 35 km in width.

Further details about the seismotectonic context of this sequence are available on the Main Event Page and through an interactive geonarrative.
