| Abstract: | Using the geomagnetic data of nuclear precession in Mengcheng Seismic Station, the sta tistics analysis on b-value was performed and the basic law of short-term, long-term and cyclical changes was obtained. Taking some moderate and strong earthquakes in East China as example, the results of correlation analysis showed that the b-value anomalies may have the effect of earthquake preparation and prediction significance in moderate and strong earthquakes. |
