Tectonic Reconstruction of the Evolution of the Alpine-Himalayan Orogenic Chain. This project will construct a computationally explicit model of movements in the solid Earth for the past 150 million years, to study the Earth as a complex system during the collision that produced the Alpine-Himalayan mountain belt. This is the youngest collisional mountain belt on Earth, and at times it stretched from Spain to New Zealand.

This project will construct a computationally explicit model of movements in the solid Earth for the past 150 million years, to study the Earth as a complex system during the collision that produced the Alpine-Himalayan mountain belt. This is the youngest collisional mountain belt on Earth, and at times it stretched from Spain to New Zealand. Earth Scientists want to understand the processes that took place to make it, in particular the role of ribbon continents. As a result of this work ordinary Australians will be able to better perceive their interactions with their nearest neighbours.Read moreRead less
Multi-arrival wavefront tracking for improved seismic imaging of the Earth's interior. The complex nature of many seismic wavetrains can usually be attributed to the multi-pathing of elastic wave energy between source and receiver. Typical analysis, e.g., seismic tomography, uses few of these arrivals. This project is designed to improve the exploitation of the information on seismograms by tracking the various arrivals in complex media to provide better constraints on Earth structure. To achiev ....Multi-arrival wavefront tracking for improved seismic imaging of the Earth's interior. The complex nature of many seismic wavetrains can usually be attributed to the multi-pathing of elastic wave energy between source and receiver. Typical analysis, e.g., seismic tomography, uses few of these arrivals. This project is designed to improve the exploitation of the information on seismograms by tracking the various arrivals in complex media to provide better constraints on Earth structure. To achieve this goal, new methods for constructing multi-arrival wavefronts will be developed and applied to a range of seismic data from Tasmania to produce high resolution images of the crust and upper mantle.
