Seismic ringing effect in the shallow subsurface

摘要

We refer to the seismic ringing effect as a dynamic response of a localized shallow heterogeneity in the ground to an incident wave field originated either from a seismic source operating at the surface or from a background noise. On the seismograms the seismic ringing wave field usually appears as a long wave train with a pronounced resonant character concentrated above the localized subsurface heterogeneity.
