A powerful magnitude-7.5 earthquake struck off Japan's eastern Honshu coast late Monday, triggering tsunami warnings across northern Pacific regions. The China Earthquake Networks Center reported the quake occurred at a depth of 50 kilometers, while the Japan Meteorological Agency measured it at magnitude 7.6 near Aomori Prefecture.
Authorities issued immediate tsunami alerts for Hokkaido, Aomori, and Iwate prefectures, with waves potentially reaching 3 meters. Residents in coastal areas were urged to evacuate to higher ground. The tremor revived memories of the devastating 2011 Tōhoku earthquake, though early assessments suggest less severe infrastructure damage this time.
Regional neighbors including China and South Korea have activated emergency monitoring systems. The Chinese mainland's coastal stations reported no immediate threats to its shoreline as of Tuesday morning. Meteorological agencies across the Pacific Rim continue coordinated tracking of potential wave impacts.
