Abstract:

In order to understand high frequency wave propagation, precise methods of generation of synthetic seismograms are required. This report examines the trapezoidal integration rule used by Bouchon to evaluate Hankel transforms of the Sommerfeld kernel. Numerical problems arise for integrals of some J sub 0 kr functions. A modification of the numerical integration technique, using a shifter mid-point rectangular rule rather than a trapezoidal rule alleviates some of the problem. For calibration of numerical integration techniques, the Haskell solution for point sources in a wholespace are extended. Keywords Synthetic seismograms and Numerical integration.
