Magnitude 7.6 Earthquake Strikes Off Japan's Northeastern Coast, Prompting Tsunami Warnings

A magnitude 7.6 earthquake struck off Japan's northeastern coast on December 8, 2025, at 11:15 p.m. local time, prompting tsunami warnings and evacuations for approximately 90,000 residents. The Japan Meteorological Agency (JMA) warned that tsunamis up to 3 meters (10 feet) could impact coastal areas, with smaller waves already observed. The quake, centered 80 km off Aomori Prefecture at a depth of 54 km, registered an "upper 6" on Japan’s seismic intensity scale in Hachinohe city, causing potential structural damage and injuries.

So far, only minor injuries (seven confirmed) have been reported, and no major damage or casualties. Rail services were suspended, and some power outages occurred but were later partially restored. No irregularities were detected at nearby nuclear facilities. Given Japan’s location in the earthquake-prone Pacific "Ring of Fire," the JMA issued a one-week advisory for potential aftershocks. The region previously endured a devastating 9.0-magnitude quake and tsunami in 2011, which led to nearly 20,000 deaths and a major nuclear crisis in Fukushima. This latest event caused the yen to momentarily weaken on currency markets.
