| Abstract: | The earthquake of MS 5.3 occrred at the Qiqing town Sunan county in Gansu province has been systematicaly analyzed. The features of seismicity and the characteristics of anomalies of before the earthquake are studied. The earthquake sequences is mainshock type. The value of b is 0.38;h value is 0.9; and the energy release of mainshock is 99. 1 percent of all earthquake sequences. The characteristics of the event sequence is high strong and low frequency. The distribution of remainshock is more concentrated and the direction is N E. |
