摘　　要：信号震是一种广义的前震;信号震地热前兆异常和主震地热前兆异常相似;信号震和主震沿同一构造体系活动;深入研究信号震与主震地热前兆异常的关系及地热异常特征和震源机制的关系,可能对地震预报的实践有一定的指导意义。Signal earthquake is a kind of generalized foreshock. Geothermal precursory anomaly before signal earthquake is similar to the anomalies before main earthquake. Signal earthquake and the major earthquake seem to be controlled by the same tectonic system. It is significant to earthquake prediction to study the geothermal precursory anomaly before signal and major earthquake as well as their relation with focal mechanism.
