| 摘 要： | 本文计算了地球自转速度季节性变化与全球强震季节性频度曲线的相关性,相关系数与震级有关,並发现强震频度的纬度分布与离心力大小有关,从而可能找到地球自转触发地震的某些依据。並用地下水异常、激光锁相应变仪测到的地震前兆,分析了地球自转短周期与地震的关系。

| Abstract: | In this paper,we have computed the correlation between the seasonal velocity variations of earth rotation and the seasonal frequent curves of strong earthquakes.The correlative coefficient is related to the earthqua-ke magnitude.And we found that the latitude distribution of strong ear-thquakes relates to centrifugal force,hence we have found some evidence about earth rotation inducing earthquakes.We have also analysed the relation between short cycle of earth rotation and earthquakes,according to the anomaly of underground water and the forerunner of earthquakes measured by laser lock-paper strain instruments. |
