Summary: Theoretical seismograms of waves propagating in an elastic medium consisting of four layers are given. The seismograms are computed by the method of summation of kinematic and dynamic analogs of these waves. On the basis of these computations, some conclusions are made on the behavior of wave field at large distances.
