A powerful offshore earthquake registered at magnitude 6.7 on Friday, prompting authorities to issue a tsunami advisory and briefly raising alarms across coastal communities. While the event produced only small tsunami waves and caused no reported injuries or significant damage, it heightened regional concerns already elevated by a stronger earthquake earlier in the week.
The temblor struck at 11:44 a.m. local time at a depth of roughly 20 kilometers (12.4 miles). Seismologists noted that the quake originated off the east coast of Aomori Prefecture, in the northern reaches of Honshu. The Japan Meteorological Agency responded quickly, issuing a tsunami advisory for vulnerable coastal areas. That advisory was lifted approximately two hours later after wave activity remained minimal.
Small tsunami waves were observed along portions of Hokkaido and Aomori, though emergency officials confirmed that no injuries, major structural damage, or disruptions to critical infrastructure occurred. Even so, the quake added tension to a region still unsettled by a magnitude 7.5 earthquake that struck on Monday, causing dozens of injuries, scattered power outages, and modest structural impacts. During that earlier event, tsunami waves exceeding two feet (0.6 meters) were recorded at Kuji Port in Iwate Prefecture, leading to temporary evacuations and extensive monitoring.
Authorities had already warned residents this week to be prepared for aftershocks, and Friday’s quake provided a stark reminder of the area’s volatility. Experts also noted a slight increase in the statistical risk of a much larger seismic event—potentially magnitude 8 or stronger—along a broad stretch of coastline extending from Chiba, east of Tokyo, all the way to Hokkaido. Officials stressed that this is not a prediction but a precautionary advisory meant to reinforce preparedness and awareness.
The region’s vulnerability carries historical weight. The latest seismic activity has occurred near the zone impacted by the catastrophic 2011 magnitude 9.0 earthquake and tsunami, a disaster that claimed nearly 20,000 lives and led to the Fukushima Daiichi nuclear plant meltdown. While Friday’s quake proved comparatively mild, the memory of 2011 ensures that even moderate seismic events are taken seriously by residents and authorities alike.
For now, life has largely returned to normal, but officials continue urging coastal communities to remain vigilant, review evacuation routes, and stay informed as aftershocks remain possible.
