Powerful Quake Strikes Northern Japan, Tsunami Advisory in Effect

On the evening of November 9, 2025, a powerful 6.7 magnitude earthquake rattled the northern coast of Japan. The quake, which struck off the coast of Iwate prefecture at a depth of 10 kilometers, was followed by several more tremors in the region.

In response, the Japan Meteorological Agency issued a tsunami advisory for the northern coastal areas, warning of potential waves up to 1 meter (3 feet) high. While no immediate reports of injuries or major damage have surfaced, the quakes did cause power outages and disruptions to bullet train services in the affected areas.

Tsunami waves of around 10 centimeters (4 inches) were detected in several coastal cities, including Ofunato, Ominato, Miyako, and Kamaishi. Authorities cautioned that the tsunami threat could continue for a few hours, with the waves potentially growing larger over time. Residents were advised to stay away from the coastline due to the ongoing danger.
