| 摘 要： | 磁暴二倍法预报地震的依据是，应变能在运移过程中导致地壳膨胀和压缩形成一个周期，在时间上呈有二倍关系．唐山７．８级地震是我国７０年代最大地震，用磁暴二倍法推出有４组磁暴能对应这次地震．每组磁暴前后都发生了地震，由于这些地震释放的剩余能量在聚积过程中，地壳发生膨胀和压缩，地磁场就受到影响形成了磁暴．因此磁暴与地震能量变化有相关性．可见，磁暴二倍法可以预报地震．

| Abstract: | The basis to predict earthquakes by the double magnetic storm time method is that the crustal expansion and contraction caused by the migration of strain energy present a cycle with a double time relation.The Tangshan MS7.8 earthquake was the strongest one in 1970s in our country,it had a relation to four groups of magnetic storm energy based on the double magnetic storm time method.Every group of magnetic storm was headed or followed by earthquakes.When the residual energy accumulating after these earthquakes,the crust expanded and contracted,the geomagnetic field was affected and the magnetic storm formed.So the magnetic storm has a relation to variation of earthquake energy and earthquakes can be predicted by the double magnetic storm time method. |
