Project Description
THIS FORTRAN PROGRAM CALCULATES THE EXACT SEISMIC 2D RESPONSE FROM A
COMPRESSIONAL 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.
