A strong earthquake centered off the coast of northeastern Japan shook buildings as far as Tokyo and led to a tsunami warning for coastal areas of the northeast. The warning has since been lifted.
The earthquake had a preliminary magnitude of 7.3, the U.S. Geological Survey said, adding that there was no risk of a widespread tsunami. That was revised from an earlier estimate of 7.4.
A tsunami warning was issued for the coast of Miyagi Prefecture in northeastern Japan, which was hit by a devastating earthquake and tsunami in March 2011.
That quake triggered fuel-rod meltdowns at the Fukushima nuclear plant, causing radiation leakage, contamination of food and water and mass evacuations in the world's worst nuclear crisis since Chernobyl in 1986.
