A strong and shallow earthquake, recorded by the USGS as magnitude 6.1, struck near the coast of Kamchatka, Russia, at 08:44 UTC on November 3, 2025. The depth was reported at 10 km (6.2 miles), a detail confirmed by both the USGS and EMSC.
Epicenter Details
The epicenter was located:
-
135 km (84 miles) southeast of Petropavlovsk-Kamchatsky (population 181,216)

138 km (86 miles) southeast of Vilyuchinsk (population 25,204)

There is no tsunami threat from this earthquake.
The USGS issued a Green alert for both shaking-related fatalities and economic losses, indicating a low probability of casualties or major damage.
Most of the population in this region lives in structures designed to withstand earthquake shaking, though some vulnerable building types still exist. These include adobe block and unreinforced brick with mud construction.
Between 07:00 and 08:00 UTC on November 3, the region experienced one M5.8 and two M4.8 earthquakes. Additionally, an M5.0 earthquake was recorded earlier at 01:49 UTC.
All these events are aftershocks of the M8.8 earthquake on July 29, 2025, which triggered a Pacific-wide tsunami. That powerful quake ranked as the sixth strongest ever recorded instrumentally and ruptured a large segment of the Kuril–Kamchatka subduction zone. Ground displacement was detected across southern Kamchatka.
