A powerful 7.4-magnitude earthquake shook Russia’s Far East Kamchatka Peninsula on Saturday, September 13, 2025, according to the United States Geological Survey (USGS).
The quake struck about 112 kilometers east of Petropavlovsk-Kamchatsky at a depth of roughly 39 kilometers.
The Pacific Tsunami Warning Center (PTWC) said there was no threat of a tsunami. Japan’s Meteorological Agency noted minor sea level changes but confirmed there was little risk of damage.
Kamchatka lies on the Pacific “Ring of Fire,” one of the most active seismic regions in the world. The area has a history of very strong quakes, including a magnitude 8.8 event in July 2025 that triggered widespread tsunami alerts, as well as earlier destructive quakes in 1737, 1841, 1923, and 1952.
Authorities reported no immediate casualties or major damage from Saturday’s quake, though monitoring continues as aftershocks remain possible.
The event is another reminder of the region’s vulnerability to seismic activity and the importance of maintaining early warning systems.
