7.3 quake off Japan prompts tsunami warning

A strong earthquake struck Friday off the coast of northeastern Japan in the same region that was hit by a massive earthquake and tsunami last year. A city in the region reported that a small tsunami had hit, but there were no immediate reports of injuries or damage. The Japan Meteorological Agency said the earthquake had a preliminary magnitude of 7.3 and struck in the Pacific Ocean off Miyagi prefecture at 5:18 p.m. (0818 GMT). The epicenter was 6.2 miles beneath the seabed.
