The parameters used were $A = -4.0$, $B = 1$.
\subsection{The primary GMPE used was Chiou and Youngs (2008). The SE Australia-specific relation of Allen (2012) was also tested on number of models. Although no explicit weights are attached to the models, it is noted that the 2012 Australian earthquake Hazard map weighted the above equations equally (25 \% percent) along with two other equations used. Hoult (2013) shows that Chiou and Youngs (2008) provides a reasonable average of Australian-specific GMPEs, i.e. that that weightings used in the 2012 AEHM would result in an averaged GMPE close to Chiou and Youngs (2008).}
\subsection{Model domain}
All models were calculated on a rectangular grid that enclosed the state of Victoria. Sources were defined in a polygon that extended to a 300 km buffer around Victoria. The grid resolution was 0.1 degree. While the hazard outputs extend beyond the state of Victoria (due to the ease of computing on a square grid rather than a complex polygonal grid) the results are only valid for within Victoria.
