Abstract: In this paper, the station and anomaly density distributions are obtained by two-dimensional scan for station distribution and precursor anomaly distribution.According to that there is a probability of k anomalies in station density value n for each point, we take the reciprocal of the probability as the comprehensive seismic information quantity of seismic precursor anomalies, thus a regional distribution map of comprehensive seismic information quantity is obtained.This has provided a method with certain objective ctandard for comprehensive prediction of earthquake.
