Petropavlovsk-Kamchatsky: A powerful earthquake with a magnitude of 7.8 struck Russia’s far-eastern Kamchatka Peninsula on Thursday, prompting tsunami warnings along the Pacific coast and brief advisories as far as Alaska.

According to the U.S. Geological Survey (USGS), the quake occurred at a shallow depth of around 10 kilometers, increasing the strength of ground shaking across the region. Russia’s Emergencies Ministry later reported the magnitude at 7.2. The epicenter was located near Petropavlovsk-Kamchatsky, a city on the peninsula that is home to over 180,000 residents.

The quake was followed by a series of aftershocks, the strongest reaching 5.8 in magnitude. Despite the strength of the tremors, authorities reported no casualties or structural damage. Governor Vladimir Solodov said emergency services were placed on high alert, with teams dispatched to inspect schools, hospitals, and residential areas.

The Russian Emergencies Ministry issued tsunami warnings for Kamchatka’s eastern coastline and parts of the Kuril Islands. The Pacific Tsunami Warning Center in the United States also announced advisories for Alaska, though these were later lifted. Coastal monitoring stations recorded tsunami waves ranging between 30 and 62 centimeters.

Residents reported household items and light fixtures swaying, and some people gathered outdoors during the tremors. Videos shared on social media showed kitchen furniture rattling and chandeliers swinging. Authorities urged the public to remain cautious due to the risk of further aftershocks.

Kamchatka is one of the most seismically active regions in the world, lying along the volatile Pacific “Ring of Fire.” This latest quake is the second major seismic event of magnitude above 7 recorded in the area within a week.

While no immediate damage has been confirmed, experts warn that aftershocks could continue in the coming days, posing risks to infrastructure and coastal settlements. Emergency inspections are ongoing to ensure the safety of residents and critical facilities.
