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
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.
The Cenozoic tectonic evolution of East and Southeast Asia: interplay between the India-Eurasia collision and the Pacific and Sunda subduction zones. This project investigates how the Indo-Australian and Pacific tectonic plates have interacted with the Eurasian plate to form the largest continental deformation zone on Earth in East Asia, stretching from the Himalayas to Indonesia and eastern Siberia. This is important for understanding how mountain ranges form and how continents are torn apart.

Summary
Investigating the formation of the continents: Ontong Java Plateau as a modern day analogue. The formation of the continents has been obscured by billions of years of history. It has been proposed that the Ontong Java Plateau is a modern day analogue for the continents. The Ontong Java Plateau is a huge submerged volcanic edifice, half the size of Australia. This project will seismically image the interior of the Earth beneath the Ontong Java Plateau and use these images as constraints to develo ....Investigating the formation of the continents: Ontong Java Plateau as a modern day analogue. The formation of the continents has been obscured by billions of years of history. It has been proposed that the Ontong Java Plateau is a modern day analogue for the continents. The Ontong Java Plateau is a huge submerged volcanic edifice, half the size of Australia. This project will seismically image the interior of the Earth beneath the Ontong Java Plateau and use these images as constraints to develop a model for its origin and evolution. This work has implications for understanding the formation of the continents and the factors that have enabled their stability for billions of years. A better understanding of continent formation may benefit Australia by yielding insights into economic resources, plate tectonics and geohazards.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.

Summary
The role of subduction initiation in the evolution of Earth’s oceans. An outstanding question in plate tectonics is how do oceans start to close? The Wilson Cycle describes the life of an ocean in three phases: opening and spreading, foundering of its passive margins and development of new subduction zones, and consumption and closure. It has been suggested that new subduction zones are difficult to form and thereby they are more likely to spread from ocean to ocean like a sort of invasive mecha ....The role of subduction initiation in the evolution of Earth’s oceans. An outstanding question in plate tectonics is how do oceans start to close? The Wilson Cycle describes the life of an ocean in three phases: opening and spreading, foundering of its passive margins and development of new subduction zones, and consumption and closure. It has been suggested that new subduction zones are difficult to form and thereby they are more likely to spread from ocean to ocean like a sort of invasive mechanism. This project aims to make use of laboratory models and plate kinematic modelling to understand how subduction zones are initiating and propagating in the Atlantic. The project aims to provide clues on how ancient oceans may have closed and whether the Atlantic is already in its turning point.Read moreRead less
Intraplate volcanism near lateral slab edges: result of deep mantle plumes or slab rollback-induced mantle flow? This project investigates how the Earth's interior (the mantle) flows near edges of tectonic plates as these plates sink into the mantle. This is important because these flows have been crucial in shaping the Southwest Pacific region bordering Australia and might be responsible for the formation of some of the largest volcanoes on Earth.
Three-dimensional subduction models of overriding plate deformation and mantle flow using laboratory and numerical methods. This project investigates the interaction of the Earth's tectonic plates at subduction zones, places where one plate sinks below another plate into the Earth. This is important for understanding the evolution of the Australian plate that has active subduction zones to the north and east, and how its geological evolution is controlled by subduction.
