	abstract = {<p>Due to the relatively low frequency of large earthquake events in Australia, and the\&nbsp;inadequacy of recorded data, engineering seismologists commonly adapt ground motion\&nbsp;prediction equations (GMPEs) developed from other regions with similar conditions to the\&nbsp;Australian continent for the calculation of acceleration and displacement response. Recent\&nbsp;improvements using high quality recorded data have given rise to Next Generation\&nbsp;Attenuation (NGA) ground motion models. However, these NGA ground motion models\&nbsp;show significant discrepancies with other ground motion prediction equations that have been\&nbsp;developed and used in Australia, and these include the models that have helped establish the\&nbsp;new Australian Earthquake Hazard Map. This paper presents a study which looks at the\&nbsp;possibility of a very rare earthquake occurring at close proximity to the Sydney CBD. The\&nbsp;suitability of use in Australia of the various available ground motion models is discussed, and\&nbsp;some of these models are used to calculate the acceleration and displacement response\&nbsp;spectra. There is a large discrepancy observed between the western North American derived\&nbsp;NGAs and some of the other Australian GMPEs. The SHAKE2000 computer program was\&nbsp;used to illustrate amplification of response at a soil site relative to that at a rock site. An\&nbsp;NGA-West 2 model, that will be available in 2013, is also shown to illustrate improvements\&nbsp;to the original 2008 NGA models.</p>},
