摘要
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 activities and the earth rotation, the paper analyzed their influence on the mediun-strong earthquake in Jiangsu province and its adjacent area. The results show that the decline of sunspot activity and the acceleration of earth rotation are beneficial of mid=strong earthquakes occurred in the area; during the period of the decline of sunspot activity and the acceleration of earth rotation, the earthquake frequency increases; additionally, the mid-strong earthquake will occur greater probability in Jiangsu and its adjacent area after Feb, 2012 by the statistical method of amplitude and phase and the sunspots forecast.
