Joint reconstruction of surface waves from a high-resolution onshore data set acquired at Forsmark, Sweden

Abstract

Summary Seismic interferometry is a technique that enables the extraction of the seismic impulse response (Green’s function) between receivers. We apply seismic interferometry to a real onshore data set with the aim to reconstruct surface waves. In this study, convolution interferometry is introduced into the reconstruction of surface waves. The convolution interferometry can be used to generate surface waves with good dispersion characteristics at far offsets. The deconvolution interferometry can reconstruct clear and consistent surface waves at near offsets. We can utilize jointly the advantages of deconvolution and convolution interferometry to produce reliable retrieved surface waves. The dispersive behavior of the retrieved surface waves can be further used to infer shallow-subsurface structure in the area.
