A magnitude 7.5 earthquake struck off the northern coast of Japan, specifically the Japan — Aomori Prefecture region, injuring at least 30 people and causing damage to roads and infrastructure. The Japan — Japan Meteorological Agency initially issued tsunami warnings, which were later lifted as the largest waves measured 70 centimeters. Approximately 2,700 homes in Japan — Aomori Prefecture experienced power outages, but electricity was largely restored by the following morning. Prime Minister Sanae Takaichi confirmed the injuries and urged residents to remain vigilant for potential aftershocks. Tokyo Electric Power Company reported no abnormalities at its Higashidori and Onagawa nuclear power plants. The event highlights Japan's position on the Pacific 'Ring of Fire' and its susceptibility to seismic activity, with government estimates predicting a high probability of a future 'megaquake' with significant potential damages.
