It has been 20 days and a week since the occurrence of the earthquake off the coast of Fukushima Prefecture, which observed violent shaking with a seismic intensity of 6 or higher in Fukushima and Miyagi prefectures.
The Japan Meteorological Agency says that the direct aftershocks caused by this earthquake are on the decline, but the impact of the huge earthquake 10 years ago will continue for a long time, and we want you to prepare for severe shaking and tsunami. ..
In the magnitude 7.3 earthquake that occurred off the coast of Fukushima Prefecture after 11:00 pm on the 13th of this month, violent shaking with a seismic intensity of over 6 was observed in Soma City, Kunimi Town, Shinchi Town, Miyagi Prefecture, and Zao Town, Miyagi Prefecture. We observed a little less than 6 tremors in various parts of Fukushima and Miyagi prefectures.
The height of the observed tsunami was about 20 cm at the maximum because it occurred in the plate on the sea side subducting under the Japanese archipelago, but the tremor was transmitted over a wide range, and the tremor with a seismic intensity of 1 or more was transmitted. , Was observed from Hokkaido to the Chugoku region.
According to the Japan Meteorological Agency, there were 81 aftershocks in which tremors with a seismic intensity of 1 or higher were observed by 5 am on the 20th, of which 6 were tremors with a seismic intensity of 3 or higher.
The Japan Meteorological Agency says that the number of direct aftershocks caused by this earthquake is decreasing, but the area off Fukushima Prefecture has been active since the huge earthquake 10 years ago, and the scale will continue for a long time. There is a risk of a big earthquake in Fukushima.
On top of that, depending on the location and mechanism of the epicenter, it may be accompanied by a tsunami, so I would like you to continue to prepare for severe shaking and tsunami.
