An earthquake with a magnitude of 6.1 has been detected off the coast of Japan.
The US Geological Survey said that the earthquake struck about 286km south east of Kamaishi, and around 321km east of Fukushima.
The depth of the earthquake, which struck at 2.37am local time, was measured at 10km. Details of any damage are yet to emerge.
A tsunami sparked by an earthquake in the Pacific hit the nuclear plant in Fukushima in 2011 causing a major disaster – with the water disabling the emergency generators required to cool the reactors at the plant after they had automatically shut down.
Residents of the area were evacuated, and an exclusion zone was set up. The zone was eventually made smaller and residents have recently been allowed to return to some areas.
The incident led Japan to close all 54 of its nuclear plants for a time, while five are now back online.
