A powerful magnitude 6.9 earthquake struck off the coast of northern Japan on Thursday, prompting brief concern in affected areas but no tsunami warning, according to the Japan Meteorological Agency (JMA).
The earthquake occurred off the coast of Iwate Prefecture at a depth of about 50 kilometres. The tremor was felt across parts of northern Japan, with residents reporting noticeable shaking, although there were no immediate reports of deaths, injuries or major structural damage.
The JMA said the quake did not pose a tsunami threat, easing fears of coastal flooding that often follows strong offshore earthquakes in the region. Authorities, however, continued to monitor the situation and urged residents to remain alert for possible aftershocks while emergency services assessed the impact.

Japan is among the most earthquake-prone countries in the world because it lies on the Pacific Ring of Fire, a seismically active zone where several tectonic plates meet.
The country experiences thousands of earthquakes every year, most of them minor, but has developed some of the world’s most advanced earthquake monitoring, early warning and disaster preparedness systems.
Officials have advised residents in the affected region to follow updates from local authorities and take necessary precautions as inspections of infrastructure and public facilities continue.
