    JOINT INVERSION OF SEISMIC AND GEOELECTRIC

    This paper presents the first results of a joint inversion scheme to process underground vertical seismic profiling data, geolectric resistivity and resistance data. The joint inversion algorithm makes use of the damped leastsquares method and its weighted version to solve the linearized set of equations for the seismic and geolectric unknowns.
