This quake was likely an aftershock of the 8.8 quake North Pacific Ocean, 130 km southeast of Petropavlovsk-Kamchatskiy, Kamchatka, Russia, Jul 30, 2025 11:24 am (GMT +12), which had occurred 6 weeks earlier.

I felt this quake
A powerful magnitude 7.4 earthquake occurred in the North Pacific Ocean 361 km (224 mi) from Kamchatka,
Russia,
in the early afternoon of Saturday, Sep 13, 2025 at 2.37 pm local time
(Asia/Kamchatka GMT +12). The quake had a shallow depth of 39 km (25 mi)
and was felt over a large region. The shallow depth of the quake
caused it to be felt more strongly near the epicenter than a deeper
quake of similar magnitude would.

Major magnitude 7.4 earthquake at 39 km depth
13 Sep 02:43 UTC: First to report: VolcanoDiscovery after 6 minutes.
13 Sep 02:45: Now using data updates from USGS
13 Sep 02:57: Magnitude recalculated from 7.7 to 7.4. Hypocenter depth recalculated from 10.00 to 39.47 km (from 6.2 to 25 mi). Epicenter location corrected by 11 km (7 mi) towards NW.

Update Sat, 13 Sep 2025, 02:48
Very strong earthquake of magnitude 7.7 just reported 120 km east of Petropavlovsk-Kamchatskiy, Russia

The
United States Geological Survey reported a magnitude 7.7 quake in
Russia near Petropavlovsk-Kamchatskiy, Kamchatka, only 10 minutes ago.
The earthquake hit around noon on Saturday, September 13th, 2025, at
1:37 pm local time at a shallow depth of 10. km. The exact magnitude,
epicenter, and depth of the quake might be revised within the next few
hours or minutes as seismologists review data and refine their
calculations, or as other agencies issue their report.
A second report was later issued by the German Research Centre for Geosciences (GFZ), which listed it as a magnitude 6.5 earthquake. Other agencies reporting the same quake include The Incorporated Research Institutions for Seismology (IRIS) at magnitude 7.7, and France's Réseau National de Surveillance Sismique (RéNaSS) at magnitude 7.1.
Based on the preliminary seismic data, the quake should have been felt by everybody in the area of the epicenter. In those areas, dangerous ground shaking occurred with the potential to inflict moderate to heavy damage to buildings and other infrastructure.
Towns or cities where the quake likely caused strong ground shaking include
Moderate shaking probably occurred in Paratunka (pop. 1,800) located 145 km from the epicenter.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you're in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.
