An earthquake with preliminary magnitude of 7.3 struck Tuesday off the coast of Fukushima prefecture in Japan. A tsunami warning for waves of up to three metres (10 feet) was issued.
The Japan Meteorological Agency says the quake struck around 6 a.m at a depth of 10 kilometres (6 miles). It warned people along the coast to move to higher ground.
Fukushima prefecture is north of Tokyo and home to the nuclear power plant that was destroyed by a huge tsunami following an offshore earthquake in 2011. That earthquake killed over 15,000 people and left more than 2,000 missing.
Low tsunamis have already been reported along Japan’s east coast, and Japanese news broadcaster NHK is warning people to evacuate and not to return to low ground. It says initial tsunami waves can be low, with higher waves coming in later.
There were no immediate reports of damage or injury.
The National Tsunami Warning Center reports no tsunami warning for the west coast of North America, from Alaska south to California.
The tsunami warning for Japan has been lifted, the earthquake has been revised to 7.4 magnitude by Japanese authorities, while U.S. officials list it at 6.9.
