An earthquake registering a preliminary magnitude of 7.1 shook Kumamoto on Japan’s southern main island of Kyushu late on Tuesday (July 28, 2026) afternoon and a tsunami advisory was issued, the Japan Meteorological Agency (JMA) said.

The quake occurred at the depth of 10 km (6 miles) below the sea surface, JMA said.

No damage or injuries were immediately reported after the 4:29 p.m. quake.

The quake occurred in the western region of Kumamoto, about 900 km (540 miles) southwest of Tokyo.

The U.S. Pacific Tsunami Warning Center said there was no risk of a tsunami beyond local coasts.

No tsunami warning was ‌issued after an earthquake of magnitude ​6.9 struck the ⁠east coast of Japan’s northeastern Tohoku region, the Japan Meteorological Agency said on ‌Thursday (June 25, 2026).

The epicentre of the quake was off the ‌coast of Iwate prefecture, at ‌the ⁠depth of about 50 ⁠km, and no damage from tsunami is feared except for slight sea level ​changes, the agency ‌said.

The earthquake hit Aomori prefecture with an intensity of 6-plus, a situation where typically “it is ‌impossible to remain standing or to ​move without crawling”, on the Japanese scale ⁠of 0-7, it said.

Tohoku Electric Power said no irregularities were found at ‌its Onagawa and idled Higashidori nuclear power plants following the earthquake.

East Japan Railway said it has halted some trains, including Tohoku Shinkansen high-speed rail ‌services, after the quake.

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.
