This report discusses some of the problems experienced with recordings made in close proximity to seismic sources. New methods of modelling seismic radiation in the vicinity of the seismic source are proposed, based on the isochron approach. These methods make use of ray theory to model waveforms from finite sources, and allow the selective modelling of propagation effects for the different body wave types in arbitrarily complex three dimensional media.
