Abstract:
It is found that the regional seismic dynamics could describe all sides of regional seismic stability , thus , it should be the most v alid method to estimate regional seismic stability .Following the theory of regio nal seismic aynamics , the regional seismic stability of Weihe basin is estimated from three special topics, tha t is, earthquake implicit , earthquake generating and earthquake responding.It is found that there is multilayered intercross ear thguake implicit mode , and w hen lo cal earthquake-implicit unit meets the dynamic need of generating earthquake , the earthquake will be g enerated in the way of stick-slip .Meanw hile , up-anddown movement will happen due to the boundary effect .The earthquake-responding model is thought to be “ low er-support and upper -spreading .”
