根据太阳黑子活动和地球自转数据,分析了两者对江苏及邻区中强地震的影响。结果显示:太阳黑子活动下降段及地球自转加速度上升和转折段有利于该地区中强地震的发生;且在太阳黑子活动的下降时间内,每一个地球自转加速度的转折都会使得该地区中小地震频度增高;另外,从幅相法统计以及太阳黑子活动预测数据来看,2012年2月以后江苏及邻区的中强地震发生概率较大。
Based on the data of sunspot activity and rotation of the earth, the effects of the two on moderate earthquakes in Jiangsu and its neighboring areas are analyzed. The results show that: the descending stage of sunspots and the rise and turning of earth rotation acceleration are favorable to the occurrence of moderate-strong earthquakes in this area; and each transition of earth rotation acceleration during the descending time of sunspot activity will make the small earthquakes In addition, from the amplitude and phase statistics and forecast data of sunspot activity, the probability of moderate-strong earthquakes in Jiangsu and its neighboring areas since February 2012 is higher.
