Tokyo - A strong earthquake centered off the coast of northeastern Japan shook buildings as far away as Tokyo on Friday and triggered a one-meter tsunami in an area devastated by last year's Fukushima disaster.
The quake had a preliminary magnitude of 7.3, the U.S. Geological Survey said, adding that there was no risk of a widespread tsunami.
There were no immediate reports of death or injury.The March 2011 earthquake and following tsunami killed nearly 20,000 people and triggered the world's worst nuclear crisis in 25 years when the Fukushima-Daiichi nuclear plant was destroyed, leaking radiation into the sea and air.
Workers at the plant were ordered to move to higher ground after Friday's quake. Tokyo Electric Power Co, the operator of the Fukushima nuclear plant, reported no irregularities at its nuclear plants.
The quake measured a "lower 5" in Miyagi prefecture on Japan's scale of one to seven, meaning there might be some damage to roads and houses that are less quake resistant.
The scale measures the amount of shaking and in that sense gives a better idea of possible damage than the magnitude. The quake registered a 4 in Tokyo.
