| Abstract: | Using the spatial distribution of aftershock epicenter position,and using the method of the Newton-Raphson and the genetic algorithm to determine the main earthquake fault plane parameters,we calculated the trendency angle and the inclination angle of earthquake main fault plane for the simulation data.And we have confirmed the method validity.This method may restrain jointly the parameters of the main earthquake fault plane combining with the other data. |
