Abstract

Temporary seismograph stations were operated near Cadoux W.A. after a large (ML 6.2) earthquake on 2 June 1979 near Wyalkatchem WA, after an ML 4.3 event near there 6 January 1988. The earthquake near Wyalkatchem was the largest of a series of events at this locality which continued over a period of 15 months. Arrival times recorded by these stations are tabulated in this paper. They have been used to relocate some of the 1979 Cadoux aftershocks using the Phillip Institute of Technology EQLOCL earthquake location program. The effect of the relocations has been to move the epicentres from east of the fault complex, to west of it. This result is similar to the distribution of some accurately located 1983 earthquakes, and is consistant with the mapped fault dip. Relocations using data from the Wyalkatchem station have not resulted in a significant change in hypocentral parameters. Consistent large residuals for NWAO S phases from Cadoux events indicate the first S arrival is not SN, and is more likely to be SG.
