Shallow M6.1 earthquake hits offshore Kamchatka, Russia (Updated)
A shallow M6.1 earthquake was registered at 08:44 UTC on November 3, 2025, approximately 155 km (96 miles) southeast of Petropavlovsk-Kamchatsky, Russia. The earthquake’s hypocenter was located at a depth of 29.0 km (18 miles), with coordinates at 52.2°N, 160.4°E.
The event occurred offshore Kamchatka, in the northwest Pacific region near the Russian Far East. This area is known for its seismic activity due to its proximity to the Kuril–Kamchatka Trench, where the Pacific Plate is subducting beneath the North American Plate.
Nearby infrastructure may include major fishing ports, local harbors, and regional airfields serving the Kamchatka Peninsula, as well as maritime shipping routes connecting Russia and the Pacific.
There is no tsunami threat associated with this earthquake, based on its location and available data.
USGS issued a green alert for this event, indicating a low likelihood of casualties or damage. The maximum estimated intensity reached IV, and the significance index is 572 (on a scale that runs through 1 000), based on magnitude, felt reports, and estimated impact.
Kamchatka is part of the Pacific “Ring of Fire” and is seismically active due to tectonic interactions between the Pacific and North American plates, leading to frequent strong earthquakes in the region.
