Magnitude 6.9 (7.2) Earthquake Strikes Northeastern Japan – No Tsunami Warning Issued

On Thursday morning, June 24-25 2026, a magnitude 6.9 earthquake (later upgraded to 7.2 by the Japan Meteorological Agency) struck off Iwate Prefecture at a depth of about 50 km. Shindo intensity reached 6+ in Aomori, making standing difficult, and the shaking was felt in Tokyo. No tsunami warning was issued. Kyodo reported four injuries; Reuters noted none initially. The Tohoku Shinkansen and other rail lines were halted for safety checks, and nuclear plants including Fukushima Daiichi, Onagawa and Higashidori reported no abnormalities.

Japan lies on the Pacific Ring of Fire, generating about one-fifth of the world’s magnitude-6+ earthquakes. The Tohoku region suffered the 2011 magnitude-9.0 undersea quake and tsunami that devastated Fukushima. In April 2026 a magnitude-7.7 quake off Iwate injured at least ten people and prompted a week-long advisory for heightened seismic risk.
