Abstract
Earthquake risk maps of Australia were prepared using a computer program which selected events from a regional earthquake file and calculated maximum values of acceleration, velocity and intensity at the nodes of a half degree grid, using a scaling rule of the Kanai form Y = aebmR-c. The parameters a, b and c determined by Esteva and Rosenblueth for the Western United States of America were used. For each node on the grid the Y values were plotted against the return period (years) on logarithmic scales. The results, which were compiled from the period 1960-1972, were extrapolated to give expected values of ground acceleration, ground velocity and intensity for a fifty-year return period. These values were plotted and contoured at the following zone boundaries: [see pdf for details]. The following nine Zone-2 areas together with the maximum expected ground accelerations for a fifty-year return period were delineated: Meckering (12m/s2); Gippsland (5m/s2); Picton (4.9m/s2); Cape Otway (4.5m/s 2); Broome (4.2m/s 2); Lower Eyre Peninsula (3.8m/s2, excludes Port Lincoln); east of Carnarvon (3.2m/s2), and the Simpson Desert (4.0m/s2).
