TOKYO (AP) - Several people along Japan's northeastern coast are reported injured after a strong earthquake hit the same Japanese coast that was devastated by last year's massive quake and tsunami.
The quake generated small waves, but there are no reports of heavy damage.
Buildings in Tokyo and elsewhere swayed for several minutes.
Japan's Meteorological Agency says the quake had a preliminary magnitude of 7.3. The epicenter was 150 miles offshore, and more than six miles below the seabed.
The agency says there have been repeated, smaller aftershocks.
After the quake, authorities warned that a tsunami as high as six feet could hit, and people ran for higher ground. But the tsunami warning has been canceled.
Japan has barely begun to rebuild from last year's magnitude-9.0 quake, which triggered a tsunami that ravaged dozens of coastal communities.
