The center of the quake was 600 kilometers south of tokyo in the pacific; several buildings in the capital swayed, according to the meteorological service. However, it was only a brief scare: there were no reports of injuries or damage, and no tsunami warning was issued.
The quake occurred at a depth of 370 kilometers near the uninhabited volcanic island of tori shima in the pacific ocean. Due to the great distance from the capital, the shocks in tokyo weakened considerably. The operator of the fukushima nuclear power plant, tepco, reported no damage or problems from the damaged nuclear plant, television station NHK reported.
On 11. March 2011, a severe earthquake of magnitude 9.0 had triggered a tsunami in japan, more than 15 000 people were killed. The fukushima nuclear power plant was severely damaged. The fuel rods in reactors 1 to 3 melted completely.
In an interim report from december 2011, serious accusations were made against tepco and the japanese government. Both tepco and the responsible authorities were completely unprepared for a catastrophe of this magnitude, he said. It was the worst nuclear accident since the chernobyl disaster in 1986.
