引言 地壳运动加剧引起的宏观异常,不一定是地震的短临信息,海城地震、唐山地震等与长江——黄河中下游地区出现的大量宏观异常的对比表明,他们之间具有一定差异,并可从中总结出一些作为地震短临信息的标志。一些大震的前兆资料又表明,不同地震序列具有不同的宏观异常特点,区分这些特点对地震的短临预报也许有所裨益。 INTRODUCTION The macro anomalies caused by the intensification of the crustal movement are not necessarily short-term and short-term information of the earthquake. Comparisons of a large number of macro-anomalies occurring in the middle and lower reaches of the Yangtze-Huanghe River, such as the Haicheng earthquake and the Tangshan earthquake, show that they have some differences From which we can summarize some of the signs as short message of the earthquake. The precursory data of some large earthquakes also show that different seismic sequences have different macro-anomalous features. It may be helpful to distinguish these features from short-term and short-term earthquake prediction.
