Fault-plane solutions determined for earthquakes in northwestern Australia (6 May 1978), central Australia (25 November 1978) and southeastern Australia (4 July 1977) each indicate nearly horizontal axes of maximum compressive stress. However, the azimuths of these axes are different from the azimuths of maximum stress axes determined previously for earthquakes in each area. This may be the result of a combination of warped stress fields at the junction of geologically different crustal blocks, and faulting in weakened zones of these blocks where the strike is oblique to the regional direction of maximum stress. Results in northwestern Australia can be explained by such effects.
