江淮地震区是以5~6级地震为主的中强地震活动区,其地震活动存在百年尺度和数十年尺度的准周期性,中强地震活动存在东移和逆时针迁移二种运动,1990年以来本区与华北及华南地震区的交界带地震活跃。根据以上分析和贝叶斯估计、地震复发的条件概率预测,下世纪初可能发生6级左右地震,位置估计在本区东部的南黄海海域。苏、皖交界也有发生中等以上地震的可能。
The Jianghuai earthquake area is a moderate-strong seismic activity area mainly composed of 5-6 earthquakes. Its seismicity is quasi-periodic on the centennial scale and decades-long scale. There are two types of movement of the middle-strong earthquake activities, eastward and counterclockwise, Since 1990, there has been an earthquake in the junction between the area and the North China and South China earthquake areas. According to the above analysis and Bayesian estimation, conditional probability prediction of earthquake recurrence may cause about 6 earthquakes at the beginning of the next century, and the location is estimated to be located in the southern Yellow Sea in the eastern part of this area. At the junction of Jiangsu and Anhui, there is also the possibility of moderate-to-moderate earthquakes.
