Abstract
The inventory of over 200 fault scarps captured in GA's Australian neotectonics database, when grouped according to the spatial divisions prescribed in the recently published neotectonics domain model, allows for estimates of maximum magnitude earthquake (Mmax) to be calculated across the SCR crust of Australia. The 75th percentile value of fault scarp length for all features within a given domain was used in calculations using the average of a range of published relations. Results range between Mw 7.0 - 7.5 ± 0.2 magnitude units (Table 1), demonstrating that potentially catastrophic earthquakes are possible Australia-wide. These data form the basis for future seismic hazard assessments, including those for building design codes, both in Australia and analogous SCRs worldwide.
