Tsunami warning lifted after 7.3 earthquake shakes Japan (+video)
A powerful 7.3 magnitude earthquake shook Japan's northeastern coast, triggering a small tsunami and causing buildings to sway as far away as Tokyo. Japan officials report no fatalities from the earthquake or small tsunami.
A strong earthquake Friday struck the same Japanese coast devastated by last year's massive quake and tsunami, generating small waves but no immediate reports of heavy damage. Several people along the northeastern coast were reportedly injured and buildings in Tokyo and elsewhere swayed for several minutes.
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 Japan Meteorological Agency said. The epicenter was 10 kilometers (6.2 miles) beneath the seabed and 240 kilometers (150 miles) offshore.
The area was shaken by repeated, smaller aftershocks, the agency said. (Read more about how the Fukushima disaster affected the fishing industry)
After the quake, authorities issued a warning that a tsunami potentially as high as 2 meters (2.2 yards) could hit. Sirens whooped along the coast as people ran for higher ground.
Ishinomaki, a city in Miyagi, reported a tsunami 1 meter (1 yard) high and other towns reported smaller tsunamis.
About two hours after the quake struck, the tsunami warning was cancelled. The Pacific Tsunami Warning Center earlier said there was no risk of a widespread tsunami.
