Powerful quake hits off northern Japan; no tsunami danger

TOKYO: A powerful earthquake hit off Japan's northern coast on Thursday, but there were no reports of serious damage or injuries and no danger of a tsunami, officials said.

Japan's meteorological agency said the quake measured a preliminary magnitude of 7 and was located far off the northeastern coast of Japan's northern main island of Hokkaido. It was centered 60 kilometers (100 miles) below the ocean's surface and east of Etorofu island, a Russian-held island that is also claimed by Japan.

Officials said the quake was unlikely to cause injuries or damage because of its depth and distance from the coast.
