Magnitude 7.5 Earthquake Hits Japan, Tsunami Warnings Issued

A magnitude 7.5 earthquake struck off Japan's northern coast on December 8, 2025, at about 11:15 p.m. local time, injuring at least 23 people and triggering tsunami warnings. The quake, which occurred approximately 80 kilometers off the coast of Aomori, prompted authorities to urge nearly 100,000 residents to evacuate to higher ground.

According to the Japan Meteorological Agency, the tsunami measured up to 70 centimeters in Kuji port and 50 centimeters in other areas. Chief Cabinet Secretary Minoru Kihara reported that about 800 homes lost power and advised residents to seek shelter.

The region's nuclear plants, including the Rokkasho fuel reprocessing plant, conducted safety checks after minor water spills, but no safety concerns were reported. With the risk of aftershocks and a potential megaquake, the government set up an emergency task force to monitor the situation and assess damage.

Prime Minister Sanae Takaichi emphasized the need for preparedness, reflecting on the devastating 2011 tsunami and earthquake that resulted in nearly 20,000 fatalities. As of early Tuesday morning, advisories for tsunami surges were lifted but cautions about aftershocks remained in effect, urging residents to remain vigilant.
