In the paper, the characteristics of seismological precursors (seismic spatial correlation length and coda Q_c) associated with the earthquake (M=5. 5,) occurred in Minxian, Gansu prov-ince, on Nov. 13, 2003, are studied. The result shows an increasing trend of the both parameters before the earthquake. And a power exponent relation is used to fit the increasing variation form of the parameters. The study provids a basis for creating a method and finding indexes to predict earthquake occurrence time by using the monitored seismic spatial correlation length and coda Q_c. |
