A strong earthquake struck Friday off the coast of northeastern Japan in the same region that was hit by a massive earthquake and tsunami in March 2011. Authorities issued a warning of a possible tsunami.
The Japan Meteorological Agency said the earthquake had a preliminary magnitude of 7.3 and struck in the Pacific Ocean off the coast of Miyagi prefecture at 5:18 p.m. (0818 GMT). The epicenter was 10 kilometers (6.2 miles) beneath the seabed.
The warning said the tsunami could be as high as 2 meters (2.19 yards).
