Rapid Determination of Earthquake Sources in Australia. The Australasian region is at risk from both large earthquakes and tsunamis. Rapid and reliable determination of parameters such as depth and orientation of earthquake fault planes in real time is vital for an effective response. This project will greatly improve the quality of information inferred from seismic waveform data by using three-dimensional structural models of Earth and also provide valuable insight into the earthquake generatio ....Rapid Determination of Earthquake Sources in Australia. The Australasian region is at risk from both large earthquakes and tsunamis. Rapid and reliable determination of parameters such as depth and orientation of earthquake fault planes in real time is vital for an effective response. This project will greatly improve the quality of information inferred from seismic waveform data by using three-dimensional structural models of Earth and also provide valuable insight into the earthquake generation process. By comprehensively incorporating three-dimensional structural models in estimating earthquake sources, the project will be at the forefront of research worldwide. The science developed will underpin automated determination of characteristics of earthquakes and play a key part in efforts to mitigate the impact of tsunamis.Read moreRead less
Data Adaptive Geophysical Inversion. The goal of this project is to develop new techniques for extracting information about the interior structure of the Earth from large geophysical data sets. These methods will be adaptive so that they allow the definition of the physical model to be constrained by the character of the data. The project will utilize advances in computational geometry, nonlinear inversion and interactive computer visualisation to extract robust information from data sets with v ....Data Adaptive Geophysical Inversion. The goal of this project is to develop new techniques for extracting information about the interior structure of the Earth from large geophysical data sets. These methods will be adaptive so that they allow the definition of the physical model to be constrained by the character of the data. The project will utilize advances in computational geometry, nonlinear inversion and interactive computer visualisation to extract robust information from data sets with variable resolving power. The resulting algorithms will be applicable to a wide range of problems in the physical sciences.Read moreRead less
