Abstract：A fast simplified algorithm for generating three-component seismogram is developed after simple analysis and some simplification of the propagation of multi-component wave field in layered medium model. This algorithm uses ray tracing to calculate traveltime, and derives reflection amplitude from wave-field interface equation. The use of fast ray tracing and effective simplification speeds up; the operation of this algorithm, so that generating three-component seismogram by AST 386 personal computer only takes ten minutes to several tens of minutes.
