In early 2011 a series of natural disasters impacted a large number of communities in Queensland. The flooding in the Brisbane region and the severe wind and storm surge experienced in the tully region caused widespread damage to infrastructure and disrupted both households and businesses. The full recovery costs over the next few years are expected to be considerable and will be a major drain on the resources of all levels of government and the insurance industry.

The aim of this document is to provide the Fire and Emergency Services Authority of Western Australia (FESA) with a preliminary assessment of tsunami risk to a number of communities in South West WA. This assessment follows the preliminary assessment of tsunami impact for six North West Shelf communities and probabilistic tsunami hazard assessment for Western Australia which described the chance of a given tsunami wave height at the 50m contour being exceeded.

This summary of palaeontological data derived from Meda #1 well is based on information provided in the original well completion report and its subsequent publication (Pudovskis 1959, 1962), updated with reference to more recent palaeontological and biostratigraphic research in the Canning Basin and elsewhere. No samples have been re-examined, but in some cases this would seem to be a requirement to resolve uncertainties in dating certain horizons.

This professional opinion assesses the viability of utilising the priority aquifer target GWMAR1 to secure Broken Hill's water supply, both as an extractive only scheme and as a conjunctive use scheme employing Managed Aquifer Recharge as a key component. This work comes under the arrangements of the Broken Hill Managed Aquifer Recharge Project Phase 3a Memorandum of Understanding. The report addresses, with confidence levels, the following issues: Option 1: Groundwater Extraction Only. This includes an estimation of the water storage capacity and ambient groundwater salinity of the GWMAR1 priority target and the Jimargil sub-area. Different confidence levels are attached to these two estimates, reflecting the focus of work to date on the Jimargil sub-area. Broader groundwater quality issues will also be discussed. An assessment is also made of the issues with respect to direct groundwater extraction as the sole option for securing Broken Hill's water supply for a minimum of 3 years (approximately 30GL). Option 2 assesses the use of the GWMAR1 priority aquifer as part of a conjunctive water supply incorporating Managed Aquifer Recharge. This includes an assessment of the suitability of the priority MAR target at Jimargil based on the National MAR Risk Assessment Guidelines. The report also includes specification of the remaining information gaps and potential risks to a project to utilise the aquifer for (1) Groundwater extraction and (2) a conjunctive supply utilising Managed Aquifer Recharge. Broken Hill and Menindee. The report also includes a short summary of communities in Australia that currently rely on Managed Aquifer Recharge to supply their potable water, and management issues associated with this supply, and future considerations to a possible implementation phase of providing water security to Broken Hill and Menindee from a regional aquifer.

This document describes opportunities for supporting the Philippines CSCAND agencies to enhance their capacity to assess the risk and impact from natural hazards based on an assessment of current gaps. The CSCAND agencies include the Mines & Geosciences Bureau, the Philippine Institute of Volcanology and Seismology, Philippine Atmospheric, the Geophysical and Astronomical Services Administration, the National Mapping and Resource Information Agency, and the Office of Civil Defence. It is important to note that efforts to assess natural hazard risk are only one mechanism by which the CSCAND agencies support the reduction of disaster risk in the Philippines and that this paper covers only a part of the disaster risk reduction activity spectrum.

This document describes the current capacity of Papua New Guinea technical agencies to undertake natural hazard risk assessments. It provides an assessment of the current level of skill, products and datasets available and addresses significant gaps and limitations.
