Regarding the magnitude 7.3 earthquake that occurred off the coast of Fukushima Prefecture on the night of the 13th, the government's Earthquake Research Committee was careful about shaking with a maximum seismic intensity of 6 or higher for the next week or so, and a huge earthquake 10 years ago including off the coast of Fukushima Prefecture. We are calling for reconfirmation of preparations for shaking and tsunamis, as there is a risk of large-scale earthquakes occurring in and around the aftershock area of.
Following the earthquake off the coast of Fukushima Prefecture on the night of the 13th, the Earthquake Research Committee of the Government's Headquarters for Earthquake Research Promotion held an extraordinary meeting from the evening of the 14th to analyze the observation data.
This earthquake occurred inside the Pacific plate subducting under the Japanese archipelago, and a 20-centimeter tsunami was observed at Ishinomaki Port in Ishinomaki City, Miyagi Prefecture.
In areas where the shaking was strong, it is necessary to pay attention to earthquakes with a maximum seismic intensity of 6 or higher for the next week or so, and the aftershocks of the huge earthquake 10 years ago, including off Fukushima Prefecture, will continue to be affected. , Points out that seismic activity is becoming more active.
Therefore, it should be noted that large-scale earthquakes will continue to occur in and around the aftershock area for a long period of time, which may be accompanied by a tsunami.
Naoshi Hirata, chairman of the Earthquake Research Committee and a counselor of the National Research Institute for Earth Science and Disaster Prevention, said, "If the epicenter of this earthquake occurred a little shallower and the scale was a little larger, the tsunami could have been bigger. I would like people to check their preparations for the tsunami again. "
