Strong earthquake hits off northern Japan coast

A strong 7.2-magnitude earthquake struck off the northern coast of Japan on Thursday morning, prompting safety checks across the region but causing no immediate reports of injuries or major damage. Authorities also confirmed there was no tsunami threat.

According to the Japan Meteorological Agency (JMA), the earthquake occurred off the eastern coast of Iwate Prefecture at a depth of about 30 miles (50 kilometers). The agency later upgraded the quake’s magnitude from an initial estimate of 6.9 to 7.2. Meanwhile, the U.S. Geological Survey measured the event at magnitude 6.9.

The earthquake was felt across northeastern Japan during the morning rush hour and was also noticeable in Tokyo. The affected region has experienced several significant earthquakes in recent months, including one in December that prompted a weeklong megaquake advisory.

Chief government spokesperson Minoru Kihara said there were no immediate reports of casualties or structural damage. Prime Minister Sanae Takaichi stated that emergency response teams were gathering information and prepared to provide assistance if necessary. She also urged residents to remain alert for possible aftershocks.

In Aomori Prefecture, Tomoko Nagane, a primary school principal in Hashikami, said she was driving when an emergency earthquake alert sounded. Although the shaking frightened students, all children at the school were reported safe. Classes were canceled, and students returned home without incident.

Reports from cities including Sendai and Morioka indicated that the shaking lasted for several minutes, but no significant damage was observed. Daily activities largely continued as normal, with commuters proceeding cautiously.

As a precaution, East Japan Railway temporarily suspended some bullet train and local rail services to inspect tracks and infrastructure.

Officials also confirmed that no abnormalities were detected at nuclear facilities, including the Fukushima Daiichi nuclear power plant and a spent fuel reprocessing facility in Aomori.

Japan lies along the Pacific Ring of Fire, one of the world’s most seismically active regions, making earthquakes a frequent occurrence. Authorities continue to monitor the situation and advise residents to stay prepared for possible aftershocks
