Based on systematic analysis, nine seismometry parameters that response earthquakes well in North China are selected, which are seismic frequency, seismicity scale, mf-value, b-value, D-value,η-value, seismicity intensity entropy and seismicity time entropy.

After studying its short-term anomaly characteristics to earthquakes, the criterion index for M≥5.8 earthquakes in North China is obtained. The R-value test indicts that it has good prediction effect.
