| Abstract: | The data observed by MDCB earthquake precursor monitoring instrument within forty-two months in Langfang have been analyzed in this paper. The results show that electromagnetic wave parameters such as pseudo-crustal stress, abnormal eight-direction and anomalous frequency, which recorded by the MDCB, are corresponding to the moderate and strong earthquakes. The dynamic changes of these parameters can provide the criterion to estimate seismic distance, earthquake intensity and earthquake direction in the future. Finally, the preliminary results of the quantitative relation between the anomaly of electromagnetic wave parameters and the earthquakes occurrence have been given. |
