Abstract
A method is described for modifying an earth model including receiving an earth model containing one or more surfaces with surface geometries, such that at least two surface depth locations exist for some horizontal positions; perturbing elastic properties within the earth model; and generating a modified earth model by modifying the surface geometries within the earth model while preserving seismic travel times of the earth model such that after an initial user parameterization all updates of the surfaces are done without additional user input. The method may be executed by a computer system.
