A moderate earthquake with a preliminary magnitude of 5.9 jolted eastern Japan, including the Tokyo area, early Sunday. The country’s meteorological agency confirmed there was no tsunami threat.

The Japan Meteorological Agency reported the earthquake occurred in the southern prefecture of Ibaraki at a depth of 70 kilometers (42 miles). The United States Geological Survey recorded a preliminary magnitude of 5.8.

No damage or injuries have been reported at this time. The government set up a task force to assess potential damage. Prime Minister Sanae Takaichi stated this on social media platform X.

The earthquake triggered emergency alerts on mobile phones and shook the Tokyo area. However, public broadcaster NHK showed normal traffic conditions on streets in nearby cities including Mito and Saitama. A water main broke in Tokyo’s eastern Koto district, flooding the street, according to NHK images. About 460 homes in Tokyo experienced power outages, TEPCO Power Grid reported.

The Nuclear Regulation Authority stated there were no abnormal reports from roughly a dozen nuclear power plants and other facilities handling nuclear materials.

Last month, a 7.1 magnitude earthquake shook the Kumamoto area on Japan’s southernmost island of Kyushu. It resulted in 38 fatalities and 364 injuries, destroying over 1,500 structures and damaging nearly 20,000 more.
