[SSS11-P03] Surface wave characteristics from ambient seismic noise in Northern China
Keywords:Surface wave, Ambient seismic noise, Thick sediments
It is necessary to research the effects of thick sediments to long-period ground motion in northern China. We extract surface wave from ambient seismic noise in Northern China and analyze frequency spectrum of surface wave. Our purpose is to reveal the formation and propagation of long-period surface wave in thick sediments and to grasp the amplification effect of long-period ground motion due to the thick sediments.
