Patent abstract
To attenuate a surface seismic wave, seismic sensors having a predetermined orientation with respect to a surface are provided, where the seismic sensors receive seismic waves including a seismic wave reflected from a subterranean structure and the surface seismic wave propagating in at least a first direction that is generally parallel to the surface. A signal that represents a partial derivative of a wavefield containing the surface seismic wave is provided, and the signal is integrated to obtain a response in which the surface seismic wave is attenuated.
