TOKYO — 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 the coast of Miyagi prefecture at 5:18 p.m. (0818 GMT). The epicenter was 10 kilometers (6.2 miles) beneath the seabed.
After the quake, which caused buildings in Tokyo to sway for at least several minutes, authorities issued a warning that a tsunami potentially as high as 2 meters (2.19 yards) could hit. Ishinomaki, a city in Miyagi, reported that a tsunami of 1 meter (1 yard) hit at 6:02 p.m. (0902 GMT).
The Pacific Tsunami Warning Center said there was no risk of a widespread tsunami.
Miyagi prefectural police said there were no immediate reports of damage or injuries from the quake or tsunami, although traffic was being stopped in some places to check on roads.
