On the afternoon of the afternoon of the 14th, the day after the earthquake of magnitude 7.3 in the offshore of Fukushima Prefecture, Japan, a tiled ground was broken near a building in Fukushima Prefecture. yunhap news-It was observed that the aftershock of the Great East Japan Earthquake that occurred in 2013 will continue for more than 10 years.
In particular, the earthquake off the coast of Fukushima Prefecture, Japan, that occurred on the 13th was analyzed as an aftershock of the Great East Japan Earthquake.
According to the Mainichi Shimbun and others on the 16th, the Japanese government’s Earthquake Investigation Committee announced that the earthquake will continue to occur for the time being due to the aftershock of the Great East Japan Earthquake that occurred in March 2011.
Tokyo University Emeritus Professor Naoshi Hirata, chairman of the Earthquake Investigation Committee, said, “It has been 10 years since the earthquake in East Japan, and the number of aftershocks has decreased, but at least in the current situation, I think that such aftershocks will continue for another 10 years.”
After the Great East Japan Earthquake, the rectangular area extending north and south from Aomori Prefecture in the northernmost part of Honshu to Chiba Prefecture in the metropolitan area is defined as the area where the aftershocks of the Great East Japan Earthquake occur, that is, aftershocks. It reaches 4,647 times.
Aftershocks with a magnitude of 7.0 or more occurred five times, including the earthquake immediately after the Great East Japan Earthquake and the 13th of this month.
In this regard, Naoyuki Kato, a professor at the University of Tokyo Earthquake Research Institute, said, “When a major earthquake occurs, the fault moves and the force exerted on the rock mass is redistributed. An earthquake that occurs again to release the force is an aftershock. It is not strange that it lasts more than 100 years.” He explained.
He pointed out that the aftershock of the 8.0 Nobi earthquake in southern Gifu Prefecture in October 1891 still continues.
