The concept of a vertical barrier embedded in soil to protect from seismic waves of
the Rayleigh type is discussed. Horizontal barriers are also analyzed. The principle idea for
such a barrier is to reflect and scatter energy of an oncoming wave by the barrier, thus
decreasing the amplitude of surface vibrations beyond the barrier. Numerical FE simulations
of a plane model are presented and discussed.
