摘要: 在应用地磁绝对测量预测地震中,为适应我国大陆地磁台距大的状况,充分利用地磁场等变线有规则分布特征,使原来仅限于小台距的差值预报法扩大到大台距,并取得了一定的预报效果,自1996年以来已获得Ms ≥ 6. 0震例6组次,并在震前做了一定程度的预测。

Abstract: In order to adopt the far distance between geomagnetic stations in China's mainland and in applying absolute geomagnetic measurement method to predict earthquakes, we may make a full use of the characteristics of regular isoporic distribution and expand the difference prediction method for small station distance to large station distance. This method has some prediction effects for six strong earthquakes (MS ≥ 6.0) since 1996.
