  • This document presents an assessment of two earthquake scenarios in Melbourne. The two earthquake scenarios are considered the maximum magnitude earthquakes possible on the two fault structures; the Beaumaris Monocline and the Selwyn Fault. The assessments are based on using GA's earthquake risk modelling software, EQRM. The software is an open-source code that is capable of modelling earthquake scenario ground motion and scenario loss. Necessary inputs include the geometry of the fault structures, appropriate ground-motion and site classification models for the area concerned and exposure information describing the built environment. Impact assessment outputs include ground shaking intensity and residential loss estimates. The information from this scenario assessment can be used to inform emergency management planning and preparation in Victoria and support the national understanding of earthquake impact.

  • Natural hazards such as floods, dam breaks, storm surges and tsunamis impact communities around the world every year. To reduce the impact, accurate modelling is required to predict where water will go, and at what speed, before the event has taken place.

  • In Global ShakeMap (GSM) applications where access to real-time ground-motion data - which constrains the shaking - is often limited, we must rapidly estimate the shaking distribution in the earthquake source region using solely predictive techniques. Current ShakeMap practice is to first calculate instrumental ground motions using a Ground-Motion Prediction Equation (GMPE). These instrumental ground motions are subsequently converted to macroseismic intensities, which are employed to evaluate human exposure to potentially fatal levels of ground-shaking in PAGER (Prompt Assessment of Global Earthquakes for Response). Here, we use the combined dataset of global instrumental and macroseismic intensity ground motion data gathered for the Atlas of ShakeMaps (Allen et al., this meeting) for evaluating the GSM approach. Several commonly used GMPEs are evaluated for active tectonic crust, subduction zones, and stable continental regions. Using our preferred instrumental GMPE, we subsequently evaluate peak motion to intensity conversion equations. Finally, we evaluate several intensity prediction equations against the ShakeMap Atlas dataset. This review has led us to recommend several fundamental changes to current GSM practice, particularly in the prediction of active crustal ground motions. We also recommend that macroseismic intensities should be predicted using conversion equations that consider earthquake magnitude and distance to rupture, in addition to peak ground motions. Though not exhaustive, this review provides a comprehensive analysis of GMPEs and macroseismic intensity prediction techniques in different tectonic regimes against a large dataset of global ground motion data. The primary purpose of this study is to evaluate these techniques with a view of improving current practices in rapid ground motion prediction for the GSM and PAGER systems.

  • On 24 June 2009, Territories West - Attorney-Generals Department emailed Geoscience Australia an updated version of the shape files to the Town Planning Scheme. These are lazone.shp and rcode.shp. The data came with numerical codes for the lazones and without English descriptions for the zone types. GA decoded the lazones to field zones based on prior data. A listing of the resultant lazone fields follows: Alias Type Precision Width---------------------------------------------------Shape FIELD_SHAPEPOLY 8 0Zone FIELD_CHAR 2 40Lucode FIELD_DECIMAL 4 0Zonecat FIELD_CHAR 0 2Key FIELD_CHAR 14 0Area FIELD_DECIMAL 18 5Perimeter FIELD_DECIMAL 18 5Lga_num FIELD_DECIMAL 4 0Scheme_typ FIELD_CHAR 2 0Scheme_no FIELD_CHAR 4 0Addcode FIELD_CHAR 4 0Restcode FIELD_CHAR 4 0Alabel FIELD_CHAR 1 0Rlabel FIELD_CHAR 1 0Lazone_ FIELD_DECIMAL 0 9Lazone_id FIELD_DECIMAL 0 9Specaddcod FIELD_CHAR 0 4Slabel FIELD_CHAR 0 1 After the field zone was joined as the legend the coded data became self evident and shows areas of: Commercial, Facility, Future Urban, Horticulture, Indian Ocean, Industrial, Mining, National Parks, Public Open Space, Public Purposes, Residential, Roads, Tourist and Vacant Crown Land. For a few zones the code was unfamiliar and were left lank.The prior version of the TPS was supplied in 1998. R-Code and lazone differences are noted in the 2009 version.

  • This dataset reflects the external boundaries of all native title determination and compensation applications that are currently recognized and active within the Federal Court process. Applications that are non-active (i.e. withdrawn, dismissed, finalised, rejected or combined) are only included as aspatial records for completeness. This is a national dataset with data partitioned by jurisdiction (State), for ease of use. Applications stored for each jurisdiction dataset include applications which overlap into adjoining jurisdictions as well as applications which overlap with these for completeness. This dataset depicts the spatial definition of active Claimant and Non-claimant native title determination applications and compensation applications. Where possible these may include internal boundaries or areas excluded. Aspatial attribution includes National Native Title Tribunal number, Federal Court number, application status and the names of both the NNTT Case Manager and Lead Member where assigned to the application. Applications included on the Schedule of Native Title (Federal Court) include all registered and unregistered applications as well as determined applications that are yet to be finalized.

  • This dataset attempts to reflect the boundaries of claimant applications for Native Title as per the Register of Native Title Claims (s185, Native Title Act; Commonwealth). This is a national dataset but data is stored by jurisdiction (State), for ease of use. Applications stored for each jurisdiction dataset include applications which overlap into adjoining jurisdictions as well as applications which overlap with these. This dataset depicts the spatial record of registered claimant applications. Aspatial attribution includes National Native Title Tribunal number, Federal Court number, application status and the names of both the NNTT Case Manager and Lead Member assigned to the application. Applicants of registered applications have the Right To Negotiate (RTN) with respect to certain types of Future Acts over the area being claimed. Whilst applications that are determined are recorded on a separate register, all registered applications remain on the Register of Native Title Claims until otherwise finalised.
