| Abstract | 1. Theory predicts that in azimuths coinciding with the fault strike, the maximum in the surface-wave spectrum is at a higher period than in perpendicular azimuths. This can be used together with body
waves or independently for fault-plane determinations.
2. A method is considered which permits one to investigate the selectivity of a system of stations used in fault-plane studies. The method also simplifies subsequent interpretation.
3.
Some simplified methods to obtain a source model are investigated. A model, obtained by analogy with dislocation theory, is shown to correspond to a peculiar distribution of pre-faulting stress which cannot correspond to a real source. |
