ABSTRACT
Computation of a synthetic seismogram associated with an assumed seismic source is possibly the first step towards computation of a hazard map of the earthquake affected region. Essentially, the steps involved include a suitable model of the earth which will be taken as an elastic half space and a source which is assumed to trigger the earthquake. Most studies on finite sources over a circular area are usually parallel to the free surface. However, sites of earthquakes are situated at geologic faults. A finite circular source moving along a fault plane with constant velocity is assumed. The exact surface response generated at the earth’s surface is obtained by the Cagniard’s technique. Some numerical results are given.
