Summary
What's shaking down under? This project aims to determine the underlying cause of recent earthquake activity in central Australia. Of all the stable continents, Australia is surprisingly seismically active, with intra-plate earthquakes occurring relatively frequently. However, these are unpredictable, placing lives and infrastructure at risk.

This project aims to determine the underlying cause of recent earthquake activity in central Australia. Of all the stable continents, Australia is surprisingly seismically active, with intra-plate earthquakes occurring relatively frequently. However, these are unpredictable, placing lives and infrastructure at risk. This project offers the opportunity to use a new seismic experiment to improve detection of small events that may warn of a more dangerous earthquake to come, and provide sub-surface imaging of the hidden crustal boundaries and faults that are ultimately responsible. Benefits will include improved hazard assessment, and a new predictive model for exploration that relates regional seismicity, crustal faults, and mineral systems.Read moreRead less

Summary
Enabling next-generation earthquake and tsunami early warning. This project aims to develop a new approach for earthquake and tsunami early warning, avoiding many of the limitations currently present in such systems. The project will combine machine learning and artificial intelligence with state-of-the-art geophysical modelling, allowing high-quality real-time prediction of seismic hazards with full uncertainty information.

This project aims to develop a new approach for earthquake and tsunami early warning, avoiding many of the limitations currently present in such systems. The project will combine machine learning and artificial intelligence with state-of-the-art geophysical modelling, allowing high-quality real-time prediction of seismic hazards with full uncertainty information. Highlighting opportunities at the interface between geoscience and data science, the project will stimulate novel approaches, and build Australian research capacity in this area. Expected benefits include improved techniques for geophysical imaging and real-time data analysis, in addition to enhanced capabilities for mitigating the costs associated with seismic activity.Read moreRead less
New observational constraints on 2004-2007 rupture of the Sumatra megathrust. This project will develop innovative methods and generate new data for studying the rupture of giant subduction zone earthquakes and the generation of destructive tsunamis. This will lead to a better understanding of these phenomena that will enhance our ability to forecast, warn and map the hazards associated with them.
Earthquake hazard in Indonesia. This project will deliver breakthrough science that will strengthen Indonesia's ability to reduce its vulnerability to earthquake disasters. This will be achieved through a collaboration of Australian and Indonesian scientists who will fundamentally improve understanding of the destructive potential of Indonesian earthquakes.
Next-generation tsunami warning. This project generates the science for rapid tsunami forecasts of sufficient accuracy and detail to maintain public confidence in tsunami warnings. It will show how next-generation warning systems can assimilate multi-sensor data to provide probabilistic forecasts enabling emergency managers to make well-informed decisions about imminent tsunamis.
Enhanced 3-D seismic structure for Southwest Australia. The ancient cratonic lithosphere of Southwest Australia appears to have a distinct contrast in geophysical properties and complex geologic structure, while having some of the highest levels of earthquakes on the continent. The project aims to produce novel 3-D models of this region that combine new seismic data collected over two years with previously collected geophysical datasets from the partner investigators. A compilation of 3-D models ....Enhanced 3-D seismic structure for Southwest Australia. The ancient cratonic lithosphere of Southwest Australia appears to have a distinct contrast in geophysical properties and complex geologic structure, while having some of the highest levels of earthquakes on the continent. The project aims to produce novel 3-D models of this region that combine new seismic data collected over two years with previously collected geophysical datasets from the partner investigators. A compilation of 3-D models will subsequently be developed, to form an effective characterisation of the geologic structure of the craton and its margins. These models will provide enhanced assessment of seismic ground shaking from regional earthquakes and facilitate an improved understanding of mineral resource potential. Read moreRead less

Summary
A new seismic facility for investigating tectonic collision zones, earthquake hazards and passive imaging techniques. A new seismic facility will enable collaboration with overseas partners to better understand plate margin tectonics and earthquake hazard in our region for mutual benefit. It will also be used in pilot studies of areas endowed with deep earth resources, and in assessing regions of heightened earthquake activity in Australia.

Earth’s response to ice unloading: a unique GPS measurement from Antarctica . Earth's response to ice unloading - a unique GPS measurement from Antarctica: This project aims to deploy geophysical equipment including global navigation satellite systems within Antarctica to understand how Earth responds to changes in stress (rheology) within the crust and upper mantle (the upper ~660 km).

Earth's response to ice unloading - a unique GPS measurement from Antarctica: This project aims to deploy geophysical equipment including global navigation satellite systems within Antarctica to understand how Earth responds to changes in stress (rheology) within the crust and upper mantle (the upper ~660 km). It exploits a globally-unique natural experiment that commenced in 2002 with the break-up of the Larsen B Ice Shelf and which was followed by large-scale ice-mass unloading and rapid surface deformation. New broadband passive seismic and geodetic deformation measurements offer the promise of resolving a dichotomy between laboratory and millennial-scale determinations of Earth rheology through uniquely studying a time-scale mid-way between these extremes, whilst further strengthening Australia's emerging expertise in polar geophysics.Read moreRead less

This project aims to advance understanding of the Australia-Pacific plate boundary - the Macquarie Ridge Complex - in the Southern Ocean.
It will be the first study to elucidate the processes generating the world's largest submarine earthquakes not associated with active subduction, which may lead to understanding of how subduction initiates, the mechanism of earthquakes occurring at convergent margins, and more accurate estimates of earthquake and tsunami potential.
This study will put Australia at the forefront of Earth Science research into the evolution of tectonic plates and has the potential to better inform hazard assessment efforts in the region, benefiting policy-makers and at–risk communities along the Australia coastline.Read moreRead less
Earth's intra-plate volcanic engine. This project aims to understand the mechanisms underpinning intra-plate volcanism. Australia hosts one of the world’s most extensive intra-plate volcanic regions. However, the mechanisms driving intra-plate volcanic provinces on Earth remain poorly understood.

This project will use geodynamical models and observational data-sets from geology, geochemistry and seismology, whilst using the Australian continent as a natural laboratory. The project is expected to provide understanding about the constraints on Australia's volcanic hazard; reconcile geophysical and geochemical constraints on mantle melting; and improve understanding of mass extinctions, continental breakup and the genesis of metals, diamonds and hydrocarbons.Read moreRead less
