7.1-magnitude earthquake rocks northeastern Japan

A magnitude-7.1 earthquake struck Japan's northeastern coast Sunday, prompting a tsunami warning for the area still recovering from a devastating quake and tsunami four months ago.

The epicenter of the quake was in the Pacific Ocean off the coast of Japan's main island, Honshu, at a depth of about 6 miles.

There were no immediate reports of damage, but residents in most of the northeastern coastline were warned to evacuate.

Officials predicted a tsunami of up to 20 inches, but the initial waves were only about 4 inches.

Japan's northeastern coastline was devastated by an earthquake and tsunami on March 11 that left nearly 23,000 dead or missing and touched off a nuclear crisis at a badly damaged facility in Fukushima.
