According to the information released by the Japan Meteorological Agency, at 0:12:00 Beijing time on December 22, 2023, at 1:12:00 a.m. local time on December 22, Japan, 5Level 0**, the specific epicenter location is located at latitude 3523 degrees, east longitude 14106 degrees, the depth of the epicenter is only 10 kilometers.
At the time of this **, the tremors were clearly felt in the Tokyo metropolitan area, Yamaguchi Prefecture, Chiba Prefecture, and other areas. This ** event is already the fourth time that the level has exceeded 4 in 6 hours from 19 o'clock on the evening of December 21 to 1 a.m. on December 22Level 5, Level 5 for the third time** activity above level 0.
This activity is likely to belong to the group earthquake type activity, which refers to the fact that the main energy of the earthquake is released through multiple earthquakes with similar magnitudes, without a prominent mainshock, and the depth of the epicenter is generally shallow. As far as the current situation is concerned, this round of **activity is also in line with the characteristics of the group earthquake type**, which generally does not cause greater damage near the epicenter because of the slow release of energy.
In October this year, there was a group earthquake pattern in the waters near the Izu Islands in Japan**, and in the eight days from October 1 to October 8, there were 29 consecutive times in the waters near the Izu Islands in Japan with a magnitude of more than 5Level 0 event, although there are three of the 29 event that reach level 6Level 0 or above, but the maximum ** level is only 6Level 1. In addition, the Izu Islands are far away from the Japanese mainland, so the impact of this round of ** on the Japanese mainland is small. If the energy of this round is released according to the mainshock aftershock type, then the mainshock level is likely to reach 7Around level 0, this level will also cause some damage to the southeastern coast of Honshu** in Japan.
