Intraplate earthquakes in Australia - Intraplate Earthquakes - page 34

morphogenic earthquakes (Quigley et al ., 2010 ; Clark et al ., 2012 ) . Long-term patterns
in large earthquake occurrence, both temporal and spatial, can be deduced from the land-
scape record and used to inform contemporary earthquake hazard science. Seismicity
source parameters such as large earthquake recurrence and magnitude vary across the
Australian continent, and can be interpreted in a framework of large-scale neotectonic
domains defined on the basis of geology and crustal setting (Clark et al ., 2012 ) . Temporal
and spatial clustering of earthquakes is apparent at the scale of a single fault, and at the
1,000 km scale of a domain. The utility of the domains approach, which ties seismicity char-
acteristics to crustal architecture and geology, is that behaviours might be extrapolated from
well-characterised regions to poorly known analogous regions, both within Australia and
worldwide.
