Japan Struck by Magnitude 6.9 Quake Near Tohoku; No Tsunami Warning Issued

An earthquake of magnitude 6.9 struck the east coast of Japan's northeastern Tohoku region on Thursday, June 25, 2026, according to the Japan Meteorological Agency. The agency reported that no tsunami warning was issued, and no damage from tsunami is feared except for slight sea level changes.

The epicentre of the quake was located off the coast of Iwate prefecture at a depth of about 50 kilometres. The earthquake was recorded with an intensity of 6-plus in Aomori prefecture on the Japanese seismic intensity scale of 0 to 7, a level at which it is typically impossible to remain standing or to move without crawling.

Tohoku Electric Power stated that no irregularities were found at its Onagawa and idled Higashidori nuclear power plants following the earthquake. East Japan Railway reported that it had halted some train services, including Tohoku Shinkansen high-speed rail services, as a precaution after the quake.

Earthquakes are common in Japan, one of the most seismically active areas in the world. Japan accounts for about one-fifth of the world's earthquakes of magnitude 6 or greater. The country has strict building codes and disaster preparedness measures in place to mitigate the impact of such events.
