Origins and distributions of intraplate earthquakes. This project aims to investigate the behaviour and origin of intraplate earthquakes in Australia by developing a multi-million-year record of earthquakes using geological, geochronological, geospatial, seismological, statistical and numerical modelling data. It will use maximum credible magnitudes, maximum shaking intensities of intraplate earthquakes and spatiotemporal relationships between large prehistoric and contemporary earthquakes to im ....Origins and distributions of intraplate earthquakes. This project aims to investigate the behaviour and origin of intraplate earthquakes in Australia by developing a multi-million-year record of earthquakes using geological, geochronological, geospatial, seismological, statistical and numerical modelling data. It will use maximum credible magnitudes, maximum shaking intensities of intraplate earthquakes and spatiotemporal relationships between large prehistoric and contemporary earthquakes to improve models of future seismic hazard in Australia and globally. This will lead to improved predictions of future earthquake impacts in urban and natural environments and development of new paleoseismic techniques.Read moreRead less
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
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.
