An earthquake of magnitude ​6.9 struck Japan’s northeast coast on Thursday (June 25, 2026), but no ‌tsunami warning was issued, no injuries were immediately ​reported and no irregularities were found at ⁠nuclear facilities, the authorities said.

Japan’s government has set up an emergency team to gather information on the quake in ‌the Tohoku region and is ready for disaster relief operations, Chief Cabinet Secretary ‌Minoru Kihara told reporters.

The epicentre of the quake, ‌which ⁠was about 50 km (30 miles) deep, was ⁠off the coast of Iwate prefecture, and no tsunami damage was expected, except for slight sea level changes, the Japan ​Meteorological Agency said.

On the ‌Japanese 0-7 intensity scale, the hardest-hit area was Aomori prefecture at 6-plus, a level defined as making it impossible to remain standing or ‌to move without crawling.

Tohoku Electric Power said ​no irregularities were found at its Onagawa and idled Higashidori nuclear power plants. Nearby ⁠nuclear facilities of Tokyo Electric Power and other companies saw no abnormalities, the Nuclear Regulation Authority said.

East Japan ‌Railway said it has halted some trains, including Tohoku Shinkansen high-speed rail services, after the quake. Expressway routes in Aomori were shut for inspections.

Earthquakes are common in Japan, one of the world’s most seismically active areas. Japan accounts for ‌about one-fifth of the world’s earthquakes of magnitude 6 or ​greater.

In March 2011, the northeast coast was struck by a magnitude 9 earthquake, ⁠the strongest quake on record in Japan, and a massive ⁠tsunami. Those events triggered the world’s worst nuclear crisis since Chornobyl a quarter ‌of a century earlier.
