| Abstract: | Two well‐defined sequences of earthquakes in South Australia were recorded in January and October 1969, these being associated with main shocks of magnitude ML 4.4 and 4.1 respectively. The events occurred in a region of little previous seismic activity, near the boundary of the Adelaide Geosyncline and the Willyama Block. |
