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

A powerful 7.5-magnitude earthquake struck off Japan's northeastern coast late Monday night, prompting tsunami warnings and evacuations across several prefectures. The Japan Meteorological Agency (JMA) reported that the quake occurred at 11:15 p.m. local time, approximately 80 kilometers off the coast of Aomori Prefecture, at a depth of 54 kilometers.

The tremor registered an "upper 6" on Japan's seismic intensity scale in Hachinohe City, Aomori Prefecture, indicating severe shaking capable of causing significant structural damage. Tsunami warnings were issued for coastal areas of Hokkaido, Aomori, and Iwate prefectures, with initial forecasts predicting waves up to 3 meters. Observed tsunami heights ranged from 20 to 70 centimeters, leading to the downgrading of warnings to advisories, which were fully lifted by early Tuesday morning.

Authorities reported at least 30 injuries, with no fatalities confirmed. Infrastructure impacts included temporary power outages affecting thousands of homes, though most were restored by morning. Rail services, including the Tohoku Shinkansen, experienced suspensions and delays. No abnormalities were reported at nuclear power plants in the affected regions.

The JMA cautioned that the region could experience aftershocks and potentially larger earthquakes in the coming days. Residents were advised to remain vigilant and prepared for possible evacuations.
