TOKYO—An earthquake struck off the eastern coast of Japan, shaking buildings in Tokyo but not causing any reported damage. It was the second large tremor to hit Japan on Wednesday, following a quake that struck off the northern island of Hokkaido.
The second quake, with a magnitude of 6.1, hit around 9:05 p.m. local time, and was centered in the bay east of Chiba prefecture at a depth of about 10 kilometers, according to the Japan Meteorological Agency website.
Japanese authorities said there was no danger of a tsunami. Tokyo Electric Power Co. said it hadn't detected any problems with its nuclear reactors, including those at the stricken Fukushima Daiichi plant, located farther north. Some train lines were paused briefly, but soon resumed service.
The quake followed a magnitude-6.8 tremor that struck off the northern island of Hokkaido earlier Wednesday. That quake sparked a small tsunami wave along Japan's northeastern coast, and prompted authorities to issue an evacuation warning. It caused no apparent damage.
