Human activities on ground generate vibrations from
the point of contact as seismic waves. Seventy percent of
those seismic vibrations are transmitted by Rayleigh waves
which spread on the surface of the world. The remaining
part of that energy is moved by body waves which spread
perpendicularly to the Rayleigh waves [2, 3]. In order to
detect humans and vehicles, Rayleigh waves can be very
useful because of the transmission direction.Those vibrations
