Since the 4th of this month, the Japan Meteorological Agency has stated that the number of earthquakes in the sea near the Tokara Islands in Kagoshima Prefecture, where the number of earthquakes with a seismic intensity of 1 or higher has exceeded 200, is gradually decreasing. There is a possibility that it will continue in the future, so we need to continue to be careful. "

At a regular press conference explaining the activities of earthquakes and volcanoes, the Japan Meteorological Agency explained the situation of earthquakes that have occurred since last month and points of caution.



Among them, it is said that a large amount of seismic activity is occasionally seen in the sea near the Tokara Islands in Kagoshima Prefecture, where earthquakes have been occurring one after another since the 4th of this month, and earthquakes with a magnitude of 5 or more have also occurred.



In a series of earthquakes with epicenters near the Tokara Islands, 218 earthquakes with seismic intensity 1 or higher were observed by the 7th, but the number is gradually decreasing.



Kazuki Miyaoka, Earthquake Information Planning Officer of the Japan Meteorological Agency, said, "Although seismic activity has settled down, in the past, earthquakes continued even after the end of a particularly active period, and there is a risk of occasional large-scale earthquakes. Please continue to be careful, such as taking measures to prevent things from falling off the shelves and not passing by cliffs. "



In addition, regarding the earthquake near Izu Oshima, where seismic activity has been observed since the 4th of this month, shaking with a seismic intensity of 1 or higher was observed 24 times by the 7th, and the number has decreased since then.


Off the west coast of Izu Oshima, seismic activity is becoming more active once every one to several years due to volcanic activity.


In addition, there is no change in observation data related to volcanoes such as crustal movements.



In addition, regarding the earthquakes in Yamanashi and Wakayama prefectures where seismic intensity 5 lower was observed on the 3rd of this month, although no conspicuous earthquakes occurred near the epicenter area after that, earthquakes of the same scale for about a week after the occurrence. We continue to call attention to the possibility of this happening.
