Abstract:

The progress report describes the method of calculation of ground motions near an earthquake source, and outlines the research which has led to ten-fold improvements over the previous computational methods. It is shown that surface waves are likely to contribute strongly to near-source ground-motions. A scalar problem is described, in terms of which one may better appreciate the essential difficulties of relating dislocation and traction on a rupturing fault surface.
