By Park Si-soo
A powerful 7.3-magnitude earthquake struck northeastern Japan early Tuesday, with the country's meteorological agency issuing a tsunami warning for the region's coast, including Fukushima Prefecture.
A tsunami wave of 1-3 meters is possible, according to public broadcaster NHK. It warned people along the coast to move to higher ground.
The Japan Meteorological Agency says the quake struck around 5:59 a.m at a depth of 10 kilometers. The U.S. Geological Survey measured the magnitude at 6.9. The earthquake shook buildings in Tokyo, 240 kilometers southwest of the epicenter.
Fukushima Prefecture is home to the nuclear power plant that was destroyed by a huge tsunami following an offshore earthquake in 2011.
The operator of the plant said there were no abnormalities observed at the plant, according to NHK.
There were no immediate reports of damage or injury.
