Using the method of multi-parametric maximum probability based on Earthquake Corresponding Probability Spectrum(ECRS)and previous research results,this paper studied the earthquakes of the middle and southern parts of the Tancheng-Lujiang fault zone up to September,2015. The results of time tracking found that there are high anomaly values before almost all target earthquakes. However,the composite index is in a rising state. Spatial calculating results also confirmed the high anomalies before target earthquakes,and that the earthquake occurred in the abnormal area or nearby.
