A moderate earthquake with a preliminary magnitude of 5.9 struck eastern Japan on Sunday morning, shaking the capital Tokyo and surrounding areas. The Japan Meteorological Agency reported the tremor's epicenter was in Ibaraki prefecture, at a depth of 70 kilometers (42 miles). The U.S. Geological Survey registered a preliminary magnitude of 5.8.
Authorities reported no tsunami danger. The government established a task force to assess potential damage, according to Prime Minister Sanae Takaichi. While the quake triggered mobile emergency alerts and was felt strongly in Tokyo, public broadcaster NHK showed that traffic in nearby cities like Mito and Saitama appeared normal.
However, a water main did break in Tokyo's Koto district, causing water to spill onto the street. TEPCO Power Grid reported that approximately 460 homes in Tokyo experienced power outages. The Nuclear Regulation Authority stated that no abnormalities were observed at about a dozen nuclear power plants or other facilities handling nuclear materials.
