从地震资料的研究分析可以看出,我国海域的地震具有频度低、强度大的特点。但很少给沿海地区造成大灾难。海域地震之前,往往会引起海水、海生物等不同程度的异常,这将为探索地震预报提供一定依据。 From the research and analysis of seismic data, we can see that the earthquakes in our country have the characteristics of low frequency and great intensity. But rarely cause a catastrophe to the coastal areas. Before the earthquake in the sea area, seawater and sea creatures often cause different degrees of anomalies, which will provide some evidence for the exploration of earthquake prediction.
