Summary The effect of a simple model of a geological fault on an incident plane SH wave pulse is considered by using the approximate technique recently developed by the author for seismic wave problems involving lateral discontinuities. Calculated pulse forms are presented for the reflected, transmitted and diffracted wave fields. The technique used is shown to be successful in representing the diffraction effects of thin faults and should therefore provide a useful aid to the understanding of the inter‐action of seismic waves with truncated structures.
