Abstract
Ground roll of seismic data is mainly composed of surface waves. Surface wave analysis can be used to estimate near surface velocity models useful for static computation. We show, through a Monte Carlo inversion, that the static estimation is robust beyond the uncertainty introduced by solution non-uniqueness of surface wave inversion. Moreover we propose an approximated technique to estimate statics directly from surface wave dispersion curves without the need for inverting and retrieving the velocity model.File | Dimensione | Formato | |
