Japan Issues Tsunami Warning Following 7.7-Magnitude Earthquake

A 7.7-magnitude earthquake struck off Japan's northeastern coast on Monday, leading to tsunami warnings and evacuation orders in coastal regions. The Japan Meteorological Agency (JMA) reported that the quake occurred at 4:53 p.m. local time, with its epicenter near the Chishima and Japan Trenches.

Following the tremor, tsunami waves reaching up to 80 centimeters were observed in Iwate Prefecture. Authorities had initially warned of potential waves up to three meters and advised residents in 182 coastal towns to evacuate to higher ground.

Prime Minister Sanae Takaichi urged citizens to confirm evacuation plans and ensure they have emergency supplies. The JMA indicated a slight increase in the likelihood of a mega-quake, estimating a 1% chance compared to the usual 0.1% over the next week.

No significant damage or casualties have been reported. Bullet train services experienced brief suspensions, and over 180,000 people across five prefectures were advised to seek shelter. All nuclear facilities remained safe, according to officials.

Japan's location along the Pacific Ring of Fire makes it susceptible to frequent seismic activity. The country continues to monitor the situation closely and has urged residents to remain vigilant.
