The 2012 Australian Seismic Hazard Map - Introduction and Approach
Geoscience Australia is currently drafting a new Australian Earthquake Hazard Map (or more
correctly a series of maps) using modern methods and models. Among other applications, the
map is a key component of Australia’s earthquake loading code AS1170.4. In this paper we
provide a brief history of national earthquake hazard models in Australia, with a focus on the
map used in AS1170.4, and provide an overview of the proposed changes for the new maps. The
revision takes advantage of significant improvements in both the data sets and models used for
earthquake hazard assessment in Australia since the original map was produced. These include:
Earthquake observations up to and including 2010
Improved methods of declustering earthquake catalogues and calculating earthquake
recurrence
Ground-motion prediction equations (i.e. attenuation equations) based on response
spectral acceleration rather than peak ground velocity, peak ground acceleration or
intensity-based relations.
Revised earthquake source zones
Improved maximum magnitude earthquake estimates based on palaeoseismology
The use of open source software for undertaking probabilistic seismic hazard assessment
which promotes testability and repeatability
The following papers in this series will address in more detail the changes to the earthquake
catalogue, earthquake recurrence and ground motion prediction equations proposed for use in the
draft map. The draft hazard maps themselves are presented in the final paper.
