【Abstract】 In this paper, we investigate the precursors of large earthquakes in eastern Taiwan region by means of the reverse tracing of precursors, find the suitable parameters for seismic chains and intermediate-term patterns, and get the threshold of the patterns. Applying the linear discriminant approach to the intermediate-term patterns of seismic chains, we present an approach to find the precursors of large earthquakes. The result of data analysis show that the method can decrease the mistake rate of false predictor for large earthquakes, and the Reverse Tracing of Precursors is suitable for eastern Taiwan region.更多还原
