A strong 7.4-magnitude earthquake shook Russia’s Kamchatka Peninsula early Saturday, the U.S. Geological Survey (USGS) reported. The quake occurred about 111 km east of Petropavlovsk-Kamchatsky at a depth of 39 km.
Officials confirmed that no tsunami warning is in effect. The Pacific Tsunami Warning Center had initially issued a potential alert but later canceled it. Japan’s Meteorological Agency also confirmed that no tsunami advisory was issued for the Japanese coast.
This earthquake is the largest aftershock following the powerful 8.8-magnitude quake that struck Kamchatka on July 29. That previous tremor caused significant tsunami waves, damaged Russia’s Rybachiy naval base, and affected Japan’s east coast. Several people were injured, and evacuations were carried out in Japan due to the waves.
Kamchatka has experienced multiple strong tremors this summer. At least five major earthquakes occurred in July alone, highlighting the region’s ongoing seismic activity. Experts say this aftershock underscores the area’s continued risk for strong quakes.
So far, no casualties or structural damage have been reported from the latest earthquake. Authorities continue to monitor the situation closely. Residents are advised to stay alert and follow official guidance in case of further seismic activity.
The region’s history of earthquakes and volcanic activity makes Kamchatka one of Russia’s most seismically active areas. Scientists continue to study the area to better understand and predict future events.
The USGS and local authorities will keep updating information about any further developments. Residents and nearby communities are urged to remain cautious, although the current quake posed no immediate tsunami threat.
