Warnings of waves up to 3 meters have been issued
A 7.4 magnitude earthquake has hit Fukushima, Japan, triggering tsunami warnings.
The Japan Meteorological Agency had reported a magnitude of 7.3 before updating it to 7.4.
The epicentre of the earthquake, which was felt in Tokyo, had a depth of about 25km.
The agency has warned that tsunami waves could reach a maximum of 3 metres and could hit the coast. Residents of the affected areas have been urged to evacuate immediately.
Following the quake, a 2ft tsunami was seen at Fukushima’s Onahama Port, as was a 3ft tsunami at Soma.
A Japan Meteorological Agency spokesman said in a press conference that the tide was still rising and the affected areas could reach Miyagi prefecture.
No damage or serious injuries have been reported as a result of the initial quake, which hit at 5.59am local time. However, one woman suffered cuts to her head from falling dishes.
Tepco has been checking its nuclear plants in Fukushima, which were damaged heavily by the 2011 earthquake. The Fukushima Daini Reactor 3 cooling system has stopped working, but “no abnormalities have been observed”.
