A 7.5-magnitude earthquake struck off Japan's northeastern coast, prompting authorities to issue tsunami warnings and evacuation orders for coastal regions. The undersea quake occurred off Iwate Prefecture on the northeastern coast of Japan's main island, Honshu.

The Japan Meteorological Agency detected tsunamis following the earthquake and warned that waves could reach up to 10 feet in height. Coastal communities in the affected region were advised to evacuate as a precautionary measure.

The earthquake's preliminary magnitude was measured at 7.5, marking it as a major seismic event. The offshore location of the quake increased concerns about potential tsunami impact along Japan's northeastern coastline.

Japan sits along the Pacific Ring of Fire and frequently experiences seismic activity. The country's northeastern coast was devastated by a massive 9.0-magnitude earthquake and tsunami in March 2011 that killed thousands and triggered the Fukushima nuclear disaster.

Authorities continue to monitor the situation and assess potential damage from both the earthquake and any resulting tsunami waves. Emergency response protocols have been activated in the affected prefectures as officials work to ensure public safety.
