Box 5031 2600 GA Delft The Netherlands. 2 Shell E&P The Netherlands. Surface waves can be used for imaging near surface layers since they are sensitive to near surface heterogeneities. We developed a method for imaging shallow subsurface heterogeneities and estimating their density contrast using scattered surface waves. We consider 3D elastodynamic scattering by heterogeneities in a laterally invariant layered embedding. We represent the scattered wavefield as a domain
