【摘要】 地球自转不规则变化的加速段与苏皖及其附近地区中强地震的相关性较好。用周期图分析的拟合曲线外推至 2 0 2 0年 ,可见这次地球自转不规则变化加速段将持续到 2 0 0 4年左右。因此 ,苏皖及其附近地区中强地震活动将持续到 2 0 0 4～ 2 0 0 5年左右。根据美国NEOS提供的数据 ,目前地球自转确在加速段。更多还原

【Abstract】 The accelerative periods of the earth rotation are well respondent to the moderate earthquakes occurred in Jiangsu, Anhui and adjacent area. The fit curve from the period graph analysis can be extrapolated to 2020, this accelerative period of the earth rotation will continue to some 2004. Therefore, the seismicity period of Jiangsu, Anhui and adjacent area should continue to some 2004～2005.更多还原
