	abstract = {<p>In low-to-moderate seismicity (intraplate) regions where locally recorded strong motion data are too scare for conventional regression analysis, stochastic simulations based on seismological modelling have often been used to predict ground motions of future earthquakes. This modelling methodology has been practised in Central and Eastern North America (CENA) for decades. It is cautioned that ground motion prediction equations (GMPE) that have been developed for use in CENA might not always be suited for use in another intraplate region because of differences in the crustal structure. This paper introduces a regionally adjustable GMPE, known as the component attenuation model (CAM), by which a diversity of crustal conditions can be covered in one model. Input parameters into CAM have been configured in the same manner as a seismological model, as both types of models are based on decoupling the spectral properties of earthquake ground motions into a generic source factor and a regionally specific path factor (including anelastic and geometric attenuation factors) along with a crustal factor. Unlike seismological modelling, CAM is essentially a GMPE that can be adapted readily for use in different regions (or different areas within a region) without the need of undertaking any stochastic simulations, providing that parameters characterising the crustal structure have been identified. In addressing the challenge of validating a GMPE for use in an area where instrumental data are scarce, modified Mercalli intensity (MMI) data inferred from peak ground velocity values predicted by CAM are compared with records of MMI of past earthquake events, as reported in historical archives. South-Eastern Australia (SEA) and South-Eastern China (SEC) are the two study regions used in this article for demonstrating the viability of CAM as a ground motion prediction tool in an intraplate environment.</p>},

	abstract = {<p>In 2012 the state of Victoria experienced its largest earthquake in thirty years. The epicentre of the ML 5.4 earthquake is located near the town of Moe, within an area of elevated seismicity called the south-eastern seismic zone. The main event as well as over 200 aftershocks were recorded and located in a coordinated study by the University of Melbourne (UoM), Geoscience Australia (GA) and the Seismology Research Centre. At the time of the largest aftershock (ML 4.4), five instruments were operating within a 20km radius from the epicentre {\textendash} providing a unique near-source strong motion record. This paper presents the spectral acceleration response results captured from the two events at a range of distances. Estimations of the VS30 parameter have been obtained for the underlying soil structure of some of the recordings stations using available borehole data, soil classification maps, observation of the natural period and using the Horizontal to Vertical Spectral Ratio (HVSR) method. The acceleration response spectra calculated from the ground motions are thus at sites with estimated site-soil properties and these spectra have been compared with estimated values from potentially applicable attenuation models, including the latest NGA-West 2 functions released in 2014. These comparisons indicate the level of compatibility of spectra obtained using the actual data with predictions made using the different attenuation models. The results show a wide range of accuracy with the current attenuation models that are thought to be applicable to the region. This is of particular importance in assisting to select the most suitable attenuation models for future Probabilistic Seismic Hazard Analyses in eastern Australia (Non-Cratonic) and other regions of Australia; the results from this type of hazard analysis are highly dependent on the attenuation model chosen to represent the area of interest.</p>},
