TOKYO, December 9, 2025: A powerful 7.6-magnitude earthquake struck off Japan’s northern coast late Monday, shaking a wide area and prompting tsunami warnings across parts of the country’s northeastern seaboard. The Japan Meteorological Agency (JMA) said the quake occurred at around 11:15 p.m. local time, with its epicenter located approximately 80 kilometers off the coast of Aomori Prefecture at a depth of about 50 kilometers. The tremor was among the strongest to hit the region in recent years, registering an upper 6 on Japan’s seismic intensity scale, which indicates severe shaking capable of causing significant structural damage.
The earthquake triggered immediate tsunami alerts for Hokkaido, Aomori, and Iwate prefectures, with authorities warning residents of potential waves as high as three meters. Early reports indicated tsunami waves between 40 and 50 centimeters were observed at coastal locations including Mutsu Ogawara and Urakawa. Public broadcaster NHK issued urgent alerts, urging residents in low-lying areas to move to higher ground and remain there until official warnings were lifted. Tens of thousands of people were ordered to evacuate coastal communities as local governments activated emergency shelters. Evacuation orders were implemented swiftly across the affected regions, while emergency services deployed to assist elderly and disabled residents.
Prime Minister Sanae Takaichi convened an emergency response task force, instructing national agencies to prioritize life-saving operations and ensure clear communication with local authorities. Several injuries were reported in northern Honshu, including incidents involving shattered glass, falling debris, and a vehicle accident linked to ground subsidence in Aomori Prefecture. No fatalities have been confirmed. The Fire and Disaster Management Agency said emergency responders were conducting building inspections to assess structural safety. Power outages were reported in parts of Aomori and Iwate, though utilities restored electricity to most areas within hours.
Thousands evacuated as authorities activate emergency plan
Japan’s major transport systems were temporarily disrupted. The East Japan Railway Company suspended Shinkansen bullet train services in the Tohoku region for safety inspections. Airports in Sapporo and Sendai halted flight operations briefly while runways were checked for damage. Road closures were reported along coastal routes due to the risk of tsunami inundation and minor landslides. Nuclear safety regulators said inspections were under way at power facilities across northern Japan, including the Onagawa and Higashidori plants. Operators reported no abnormalities or radiation leaks.
The Nuclear Regulation Authority confirmed that all plants in the affected area remained offline and secure. Authorities reiterated that standard post-quake safety checks would continue through the night to confirm system integrity. The Japan Meteorological Agency cautioned that aftershocks could occur over the coming days, urging continued vigilance among residents. Coastal communities were advised to remain alert until all tsunami advisories were lifted. Government officials stressed that rescue and relief operations were ongoing, with self-defense forces on standby to provide logistical support if required.
Aftershocks expected as Japan monitors seismic activity
Japan lies along the seismically active Pacific “Ring of Fire,” where several tectonic plates meet, making it one of the most earthquake-prone nations in the world. The country’s stringent building codes and early warning systems are among the most advanced globally, a legacy of past disasters such as the 2011 Tohoku earthquake and tsunami. Monday night’s quake served as a reminder of Japan’s constant exposure to seismic hazards, even as authorities continue to enhance preparedness and rapid-response capabilities.
The JMA said it would continue to monitor seismic activity closely and provide regular updates as assessments of damage and coastal impacts progress. By early Tuesday morning, no major structural collapses had been confirmed, and tsunami warnings for some coastal zones were being downgraded to advisories. However, officials urged the public to remain cautious until conditions fully stabilized. – By Content Syndication Services.
