Magnitude 7.4 earthquake strikes off Fukushima in Japan, tsunami warning lifted
A tsunami warning for waves of up to three meters (10 feet) had been issued, but was lifted about four hours later.
A tsunami advisory for waves of up to 1 meter (3 feet) remains in place for much of the Pacific coast. The largest wave recorded was 1.4 meters (4.6 feet) at Sendai Bay.
There were no immediate reports of damage or injury.
Tsunami waves of up to 90 centimeters (3 feet) were recorded about an hour after the 6 a.m. Tuesday (4 a.m. Monday ET) earthquake, and the tsunami warning area was widened later in the morning before it was lifted.
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 Fukushima Dai-ichi plant said there were no abnormalities observed at the plant, Japanese public broadcaster NHK said.
NHK said that power was temporarily lost for cooling water for a spent fuel pool at the nearby Fukushima Dai-ni plant, but that it had been restored.
The U.S. Geological Survey initially measured the magnitude at 6.9. The earthquake shook buildings in Tokyo, 240 kilometers (150 miles) southwest of the epicenter. The meteorological agency said the quake struck at a depth of 10 kilometers (6 miles). It revised up the magnitude from an initial reading of 7.3.
