The interaction between two intersecting strike slip faults is considered by the elastostatic dislocation theory. The two intersecting faults are taken to be situated in a homogenous, elastic half space. For simplification the following assumptions are made in this paper:(1) the stresses are independently calculated in an elastic half space, that is, when the stress produced by one fault is calculated, it is assume that the other fault is not existent; (2) These independent stresses are added up, thus analysing the interaction between two intersecting faults; (3) The depth of the two fault-planes is similar.
In this paper, the interaction between two intersecting strike slip faults with the types of Y, V, X, T and+according to the above assumptions. It is shown that the interaction related to the disposition in geometry, that is, the intersecting fault in different regions near the earthquake fault is differently affected and that the theoretical results obtained may be useful in the estimation of seismic risk and also in earthquake prediction.
