Regarding this earthquake, Professor Takashi Furumura of the Earthquake Research Institute, the University of Tokyo, who is familiar with the mechanism of the earthquake, said, "It seems that the earthquake occurred at the boundary of the plate from the location and mechanism of the epicenter. Because the epicenter is relatively deep, the damage caused by the tsunami There is no need to worry, but it seems that the scale was large and caused strong tremors over a wide area. In this area, in addition to the active seismic activity for some time, the effects of the huge earthquake off the coast of Tohoku remain. Need to be careful about the same violent shaking. "
