Seismic activity off the coast of Fukushima Prefecture “More active than last year's earthquake” Earthquake Research Commission

Regarding the earthquakes that observed violent tremors with a seismic intensity of 6 or higher in Miyagi and Fukushima prefectures last month, the government's Earthquake Research Committee said that the number of earthquakes that observed tremors with a seismic intensity of 1 or higher in the vicinity exceeded 110 so far, last year. It is said that it exceeds the activity after the earthquake that occurred off the coast of Fukushima prefecture.

It is said that seismic activity is declining, but we are calling for preparations for shaking and tsunamis, saying that the impact of the huge earthquake 11 years ago will not change the situation where earthquakes are likely to occur.

The government's Earthquake Research Committee held a regular meeting on the 11th, and the post-earthquake activity of magnitude 7.4 with the epicenter off Fukushima Prefecture, which observed shaking with a seismic intensity of 6 or higher in Miyagi and Fukushima prefectures on the 16th of last month. I analyzed the situation and so on.

A magnitude 7.3 earthquake occurred near the epicenter of this earthquake in February last year. At that time, the earthquake occurred mainly on the south side of the epicenter, but this time the earthquake occurred mainly on the north side of the epicenter. It means that it is.

In addition, the number of earthquakes that occurred off the coast of Fukushima and Miyagi prefectures and observed shaking with a seismic intensity of 1 or higher reached 116 by the morning of the 11th, and is said to be more active than last year's earthquake.

It is said that the activity is declining, but last year there was an earthquake with a magnitude of about 7 just over a month after the earthquake with a magnitude of 7.3, and it is necessary to be careful about earthquakes and tsunamis in the future.

Chairman of the Earthquake Research Committee Hirata "Preparing for shaking and tsunami"

Professor Emeritus Naoshi Hirata of the University of Tokyo, chairman of the Earthquake Research Committee, said, "There is a high probability that a major earthquake of magnitude 7 class will occur off the coast of Tohoku within the next 30 years, so be prepared for shaking and tsunami. I want you to do it. "
