Abstract: By using Logistic regression, a probabilistic method for strong earthquake prediction has been introduced in this paper.The relation between seismic parameters and the probability of strong earthquake occurrence has been discussed by taking b value and r, the range of a given number of events covered in a given length of time sections in New Zealand as an example.Results show that the probability of strong earthquake occurrence has generally positive and negative correlation respectively for b value and r, which was estimated by events occurred in a time window of 1.5 year before strong earthquake occurrence.This method can be broadly applied to other anomaly distribution and the probabilistic relation of strong earthquake occurrence.
