Abstract

Abstract: The basic principle and development of ETAS (Epidemic Type Aftershock Sequence) model are introduced in this paper, and the authors use this model to analyze both Chi-Chi shock sequence in Taiwan (main shock with M_S7.6) beginning from 1999 and the Datong shock sequences beginning from 1989 main shock with M_S5.7). The authors obtained the parameter vectors of the two sequences by analyzing and calculation, and then explore the difference of the two sequences and the decay model of some sequences in different regions in our country. At last the application prospect of the model is discussed.

Key words: Epidemic Type Aftershock Sequence, Parameter vector, Decay, Maximum likelihood
