From: A new closed analytical solution for the elastodynamic half-space Green’s function
Synthetic seismograms are given in the panels a, b and c for the three forces in directions x, y and z, respectively, at the origin and the receiver at \({{{x}}}_{1}=5\) km both on the surface of a half-space with Poisson ratio of 1/3. The P and S wave velocities are 2 and 1 km/s, respectively. Mass density is \(2\times {10}^{3}\) kg/m3. The chosen source was a Ricker pulse with “characteristic” period of 1 s and centered at 5 s. The maximum load value in absolute value is \({{{R}}}_{0}\) in GN (\({10}^{9}{{N}}{{e}}{{w}}{{t}}{{o}}{{n}}{{s}})\). Results from DWN are given with continuous lines as indicated in the legends. The synthetics using EQP are superimposed with dotted thick lines. The ordinates’ unit is meters after the common factor \(2{{\pi}}{10}^{4}{{{R}}}_{0}^{-1}\) is applied
