Abstract：The observation of the faultzone trapped waves was conducted on some seismic line with dense receivers across Hoh Sai lakeMaqen fault. It is found that the faultzone trapped waves of long period and big amplitude will appear after S wave so long as the sources and observation points are located in or near the faultzone. The finite difference forward simulation also shows that the surface rupture width of the eastern segment of Hoh Sai lakeMaqen fault is 225 m while the fault width reduce to 175 m in the depth below 150 m.
