| Abstract: | This paper analyzes the weight of Z low displacement anomaly characteristics,background,and influencing factors before earthquakes.A conclusion is made that the credibility of the anomaly is high in cases of big-amplitude and high-frequency displacement;the anomaly amplitude,distance of the epicenter,the earthquake magnitude and anomaly intervals are of no significant correlations;location of the epicenter,depth and anomaly has a unique unusual relation. |
