摘要
Ambient noise tomography is a rapidly emerging field of seismological research.Applying ambient noise to earth structure research can avoid dependence of earthquake signals effectively,meanwhile,ambient noise method can obtain upper crust structure with higher resolution as well as the structure beneath urban area because ambient noise contains abundant short period information.This paper aims to analysis advantages and disadvantages using ambient noise tomography by showing its present state,process method and progress.Anisotropy inverted by a combination of ambient noise data,surface and body waves can accurately reveal crust-mantle structure and geodynamic characteristics of deep structure.Combining noise analysis and other active signal analysis techniques can further study variations of seismological parameter and physical properties before and after earthquake.
