Surface wave imaging using deep reflection seismic data: a study on the Cuonadong dome

Earth, Planets and Space, 2022
As interference waves in deep reflection data processing, surface waves are often suppressed as noise, but surface waves carry considerable underground media information, including structural information and the physical properties of rocks.
