A powerful magnitude 7.4 earthquake struck off the coast of northern Japan on Tuesday, triggering strong shaking across multiple prefectures and prompting tsunami warnings along the Pacific coastline.
The quake, which occurred at approximately 4:55 p.m. Local time, registered a maximum intensity of 6-upper on Japan’s seismic scale in Aomori Prefecture’s Hashikami Town, equivalent to strong shaking capable of causing significant damage. Areas in Iwate and Miyagi prefectures experienced 5-lower intensity, while parts of Akita recorded 4-lower shaking.
Officials issued immediate tsunami advisories for coastal regions of Iwate and central Hokkaido’s Pacific coast, urging residents to evacuate to higher ground without delay. The Japan Meteorological Agency emphasized the need for swift action, noting that waves could arrive within minutes despite the initial alert level.
In Hakodate, where local musician TERU of the band GLAY expressed concern for public safety on social media, authorities maintained a tsunami caution rather than a full warning, reflecting varying risk assessments along the affected coastline.
Although no major casualties or structural collapses were reported in the immediate aftermath, emergency services remained on high alert as aftershocks continued to be felt across the region. The event underscores Japan’s ongoing vulnerability to seismic activity along the Pacific Ring of Fire, where tectonic stress frequently generates powerful offshore quakes.
Residents are advised to stay tuned to official broadcasts and follow instructions from local authorities as the situation develops.
