Four renewal models have been applied to several seismic regions of Japan where large earthquakes occur repeatedly at fairly regular time intervals. The model parameters have been determined by the method of moments and the method of maximum likelihood. The four models represent the distributions of time intervals fairly well, though different models are best suited for different sets of data. The probability of the occurrence of the next large earthquake during a specified interval of time can be calculated easily for each model. Some sample results are presented.
