Provide 24 hour, 7 days per week earthquake monitoring and alerts |
Real-time 24 hours a day, 7 days a week earthquake monitoring, detection, analysis and alerting activities continued. Operational capability was enhanced through improvements to the National Earthquake Alerts Centre (NEAC) decision support system. Work on additional near-real-time Australian earthquake products and services is ongoing. In 2018–19, the NEAC detected, analysed and catalogued 3025 earthquakes, including 543 Australian earthquakes above magnitude 2.0 (1429 Australian earthquakes, in total, were added to Geoscience Australia’s publicly available National Earthquake Catalogue in 2018–19). The NEAC provided rapid notification to stakeholders of 38 Australian earthquakes of magnitude 3.5 or higher, including two widely felt earthquakes in the Lake Muir area of southwest Western Australia (magnitude 5.3 on 16 September 2018 and magnitude 5.2 on 8 November 2018). The NEAC detected and catalogued over 750 aftershocks in the Lake Muir sequence, including four earthquakes above magnitude 3.5. The NEAC received over 2800 felt reports from the public in relation to the Lake Muir earthquakes, and 12 387 felt reports in total for the year. The largest Australian earthquake recorded during the year was a magnitude 5.9 event northwest of Carnarvon, Western Australia, on 16 December 2018. The NEAC provided rapid notification to the Australian Government Crisis Coordination Centre (AG-CCC), and other stakeholders, for 130 international earthquakes above magnitude 6.0. The largest international earthquake during the year was magnitude 8.1 in the Fiji region on 19 August 2018. This earthquake was also the largest potentially tsunamigenic earthquake during the period. In its functional role within the Joint Australian Tsunami Warning Centre (JATWC), the NEAC provided real-time alerts of 38 potentially tsunamigenic earthquakes, including 22 within the Australian region. In December 2018, Geoscience Australia commenced support arrangements for New Zealand’s National Geohazards Monitoring Centre, in relation to monitoring for large earthquakes with potential to significantly impact New Zealand, either directly or through tsunami generation. This arrangement was formalised through an exchange of letters between Geoscience Australia and GNS Science, under the umbrella of the Australia – New Zealand Science, Research and Innovation Cooperation Agreement. |

Result |
|
Provide spatial support and advice to strengthen disaster and emergency management capabilities for the Australian Government |
Geoscience Australia provided access to critical datasets for the Australian Government disaster management and emergency services providers via the EM- LINK system. Geoscience Australia upgraded the Emergency Management Spatial Resources Directory in October 2018 and trained Australian Government Crisis Coordination Centre staff in its use, which allowed those staff to undertake spatial analysis and map generation themselves. |
|
Deliver updated information products to Airservices Australia to support air safety |
Geoscience Australia provided air chart update and production services and vertical obstructions data updates for Airservices Australia throughout the year. |
|
Develop and deliver updated information exposure information to support Australian Government programs |
Geoscience Australia released the Australian Exposure Information Platform in August 2018 to provide a self-service capability for emergency service providers requiring national exposure information. A total of 1966 individual reports were produced by 289 different users, which significantly reduced the burden on Geoscience Australia to produce customised reports. Data content in the system was updated when resourcing permitted. Datasets updated in 2018–19 included the exposure to potential disaster of buildings, institutions, infrastructure, business, agricultural zones, and heritage. |

Analysis of performance
The impact of disasters on Australia’s economy, environment and society can be significant and includes loss of life, loss of property and infrastructure, disruption to business and, disruption to people’s livelihoods. Cities and regional centres, and their supporting infrastructure, are expanding as populations grow. This increases Australia’s exposure and vulnerability to hazards.
Geoscience Australia provides disaster risk information to help Australians understand the consequences of hazard events. In 2018–19, Geoscience Australia released three types of national-scale hazard assessment: Australian Tsunami, National Seismic and Tropical Cyclone.
These assessments provided vital information to support government decision-making and assist emergency managers to better plan for and reduce the impact of hazards.
The delivery of tools such as EM-LINK and the Australian Exposure Information Platform helps decision-makers to understand who and what may be impacted in an area affected by a disaster. This helps to reduce the time taken to make decisions; gets information into the hands of stakeholders more efficiently; and informs planning to mitigate the effects of future disasters.
Geoscience Australia also provided other products and tools to support reducing disaster risk in 2018–19. They included:
- tsunami hazard modelling guidelines to facilitate appropriate standards of rigour and improve national consistency in tsunami hazard modelling
- an updated edition of Australian Rainfall and Runoff, a national guideline document that can be used for the estimation of design flood characteristics in Australia.
During 2018–19, Geoscience Australia contributed to a range of activities in the Asia-Pacific region and represented Australia at international science and technology forums to gather practical information and guidance to aid our partner countries in the Asia-Pacific region on disaster risk issues.
In collaboration with the Department of Foreign Affairs and Trade, Geoscience Australia:
- delivered a technical disaster risk reduction program between the Australian and Papua New Guinea governments
- supported the implementation of the Sendai Framework for Disaster Risk Reduction by strengthening relationships between Australian Government entities, the United Nations Office for Disaster Risk Reduction and its Asia Pacific Science Technology and Academia Advisory Group, and the secretariat for the Pacific Community
- provided technical advice and support to the 2018–22 Australia Pacific Climate Partnership, including national-scale hazard maps for each of the 14 Pacific island states involved.
Geoscience Australia also provided ongoing real-time monitoring, analysis and advice on significant, and potentially tsunamigenic, earthquakes, to help safeguard Australian and Indian Ocean communities.
