Crustal fault system dynamics and earthquake prediction. The greatest challenge in earthquake science is prediction. Yet this possibility remains elusive. However, recent advances using an innovative numerical simulation model provided the first clear evidence for an underlying physical mechanism for earthquake forecasting, and observational studies have recently identified two independent precursors suggesting that this mechanism operates in the crust. The proposed project will use advanced sim ....Crustal fault system dynamics and earthquake prediction. The greatest challenge in earthquake science is prediction. Yet this possibility remains elusive. However, recent advances using an innovative numerical simulation model provided the first clear evidence for an underlying physical mechanism for earthquake forecasting, and observational studies have recently identified two independent precursors suggesting that this mechanism operates in the crust. The proposed project will use advanced simulation models and an innovative, multidisciplinary approach to obtain an improved understanding of crustal fault system dynamics with the aim of resolving the earthquake prediction question and progressing towards the scientific underpinning needed for intermediate-term earthquake forecasting.Read moreRead less
From crust to core: probing the heterogeneity of the Earth with seismic arrays. Seismic array deployments will be used for a variety of studies including tomographic mapping of upper mantle structure, coda analysis for crustal properties and delineation of deeper Earth structure. The high resolution information on crustal and upper mantle structure will provide important detail on the building blocks of the Australian plate at depth. This class of information helps to refine our understanding o ....From crust to core: probing the heterogeneity of the Earth with seismic arrays. Seismic array deployments will be used for a variety of studies including tomographic mapping of upper mantle structure, coda analysis for crustal properties and delineation of deeper Earth structure. The high resolution information on crustal and upper mantle structure will provide important detail on the building blocks of the Australian plate at depth. This class of information helps to refine our understanding of the way that the Australian continent has been assembled with regard to the interaction of the crust and mantle and the emplacement of mineral resources.Read moreRead less

High-temperature Elastic Wave Speeds of Mantle Minerals and their Seismological Implications. Laboratory measurements of elastic wave speeds are critical for the interpretation of seismological models for the Earth's deep interior. During the past several years, research groups at ANU and Stony Brook University have separately been proving novel experimental techniques for measurement of the temperature dependence of elastic wave speeds. Now a timely collaboration is proposed in which we would ....High-temperature Elastic Wave Speeds of Mantle Minerals and their Seismological Implications. Laboratory measurements of elastic wave speeds are critical for the interpretation of seismological models for the Earth's deep interior. During the past several years, research groups at ANU and Stony Brook University have separately been proving novel experimental techniques for measurement of the temperature dependence of elastic wave speeds. Now a timely collaboration is proposed in which we would exploit access to similar temperature ranges under two very different pressure regimes to examine the mixed pressure-temperature dependence of wave speeds that is so critical for the inference of chemical composition, mineralogical make-up, and temperature variations within the Earth's mantle.Read moreRead less
Assessment of the Seismic Hazard in South-East Queensland utilizing earthquake simulations. Assessment of seismic hazard in Australia is hampered by relatively few instrumental records of past earthquakes. Supercomputer simulations of long-term earthquake activity and strong ground motion, provide an alternative method for estimating the risk posed by earthquakes. The aim of this project is to construct a physical model for South-East Queensland incorporating the major faults and rock units of ....Assessment of the Seismic Hazard in South-East Queensland utilizing earthquake simulations. Assessment of seismic hazard in Australia is hampered by relatively few instrumental records of past earthquakes. Supercomputer simulations of long-term earthquake activity and strong ground motion, provide an alternative method for estimating the risk posed by earthquakes. The aim of this project is to construct a physical model for South-East Queensland incorporating the major faults and rock units of the region. In conjunction with earthquake simulation software of the Australian Computational Earth Systems Simulator, this model will be employed to analyse the spatial and temporal variability of earthquake activity and the ground motion resulting from these earthquakes.Read moreRead less

This project aims to improve understanding of earthquakes through development of numerical simulation models for the earthquake generation process. Its centerpiece is a major international collaboration, achieved via a visitor exchange program between the headquarters of the APEC Cooperation for Earthquake Simulation in Australia and overseas centres of excellence. Earthquakes are one of the most costly and deadly natural disasters, and APEC member economies have a high earthquake risk. Recent analyses suggest earthquakes may dominate the loss potential in Australia. The complementary research programs offer an opportunity to achieve breakthrough advances in improved methods of earthquake forecasting and hazard quantification.Read moreRead less

The neo- and seismo-tectonics of northwestern Australia. Australia's two largest earthquakes occurred in NW Australia (magnitudes 7 and 7.9 in 1941 and 1906). Onshore and offshore geologic evidence indicates other such events in recent geological history. Our present seismic database records no such events. We propose to document the nature, frequency, intensity, distribution and possible causes of seismicity in NW Australia, through deployment of seismograph arrays. We will test the effects ....The neo- and seismo-tectonics of northwestern Australia. Australia's two largest earthquakes occurred in NW Australia (magnitudes 7 and 7.9 in 1941 and 1906). Onshore and offshore geologic evidence indicates other such events in recent geological history. Our present seismic database records no such events. We propose to document the nature, frequency, intensity, distribution and possible causes of seismicity in NW Australia, through deployment of seismograph arrays. We will test the effects of basement reactivation, determine the crustal structure beneath the cratonic mass, examine onshore and offshore faults, determine local and regional stress orientations and investigate implications for petroleum production in the region, and whether natural resource extraction causes local seismicity.Read moreRead less
