Discussion about the relation of coulumb stress changes and distribution of aftersocks for the case of the chi-chi earthquake
库仑应力变化与余震对应关系的初步探讨——以集集地震为例

This paper deals with the Coulumb stress change according to the fault model composed of many small faults and layered geological crust model. Then we take Chi-Chi earthquake for example, to analyza the relation of the Coulumb stress change and the spatial distribution of the aftersocks. This paper discusses the relations the Coulumb stress change on the strike fault, dip fault and the distribution of strike earthquakes and dip earthquakes, respectively. The results demonstrate that the Coulumb stress change caused by the Chi-Chi earthquake is favorable to the occurrence of aftershockes in this region.
