A method is described for first locating and then determining the position of buried objects such as pipes, fluid filled cracks, UXO, tunnels, and the like. By this method, seismic responses are analyzed for the presence of late arriving secondary waves generated by resonant objects in response to a seismic wave shot. Upon detection of such resonant waves, indicating the presence of a buried object, the location of the object can be found as providing a best fit of a computed field and recorded data. A buried resonant object can be excited remotely by illumination of a distant active source.
