Abstract

Abstract: According to the ini tial motion signs of earthquakes, w hich was provided by the focal mechanism sof tw are in “earthquake analysis and prediction system based on GIS”, the authors have obtained the focal mechanism solutions of 20 earthquakes wi th ML ≥4.0 in boundary region of Xiuyan-Haicheng in Liaoning province on 29th November 1999.And a comparison study is conducted with the focal mechanism solution, w hich w as made by Wolf' s net projection method.It is show n that the nodal plane (A, B)the st ress axes (P, T), provided by two methods are almost same.The corresponding is good.

Key words: Focal mechanism, Pwave, Spatial distribution
