Regarding the magnitude 7.4 earthquake that occurred off the coast of Fukushima Prefecture on the night of the 16th, the government's Earthquake Research Committee said that it would be necessary to pay attention to earthquakes with a maximum seismic intensity of 6 or higher for the next week or so, and it occurred in February last year. Since the earthquake off the coast of Fukushima Prefecture caused a large-scale earthquake several months later, we are calling for preparations for shaking and tsunami for the time being.
The Earthquake Research Committee of the Government's Headquarters for Earthquake Research Promotion held an extraordinary meeting from the evening of the 17th following the earthquake off the coast of Fukushima Prefecture on the night of the 16th, and analyzed observation data.
Since this earthquake occurred inside the Pacific plate subducting under the Japanese archipelago, it is necessary to pay attention to earthquakes with a maximum seismic intensity of 6 or higher for the next week or so in areas where the shaking was strong. ..
Large-scale earthquake after the February earthquake last year
On the other hand, near the epicenter of this earthquake, there was a magnitude 7.3 earthquake in February last year, but off the coast of Miyagi prefecture next door, there was a
magnitude 6.9
earthquake in March and a magnitude 6.8 earthquake in May.
For the time being, it is necessary to pay attention to large-scale shaking.
Naoshi Hirata, chairman of the Earthquake Research Committee and a member of the National Research Institute for Earth Science and Disaster Prevention, said, "I don't know if the activities will be similar to last year, but I would like you to prepare for similar activities. It is not that a big earthquake will not occur for a while, and the probability of an earthquake off the coast of Miyagi prefecture remains high. I want you to be prepared for shaking and tsunami. "
