Research on earthquake prediction from geomagnetic pulsation

Abstract

This paper has presented a research on the method of using digitized data of geomagnetic pulsation observation to predict earthquakes and the research results. According to the theory of inductive magnetic effect, the observation of geomagnetic pulsation events can detect the preseismic conductivity and structure anomalies of subsurface media more effectively than the conventional geomagnetic observations, especially the short-impending anomalies before earthquakes. Our research results have also indicated that the geomagnetic pulsation transfer function has obvious short-impending anomalies and typical anomaly forms before earthquakes. Using the proposed method, satisfactory prediction results have been obtained.
