Project Description
THIS FORTRAN PROGRAM CALCULATES THE EXACT SEISMIC 2D RESPONSE FROM A VERTICAL DIRECTIONAL POINT SOURCE IN AN ELASTIC HALFSPACE WITH A FREE SURFACE. ALL GREEN'S FUNCTIONS ARE CALCULATED ANALYTICALLY BY CAGNIARD-DE HOOP TECHNIQUE. CONVOLUTIONS WITH A GIVEN SOURCE TIME HISTORY ARE PERFORMED NUMERICALLY.
