Subduction dynamics: slabs in the mantle

Supervisor contact

Subduction zones are the most prolific producers of seismic and volcanic activity on Earth, yet many aspects of the subduction factory remain poorly understood. For example, the degree and nature of coupling between the subducting slab and its surroundings, the strength of the slab during subduction, how it deforms, and how much water is transported to the deep mantle. Surrounded by plate boundaries Australia has a unique advantageous location for recording earthquakes originating from nearby subduction zones. Various seismic techniques and observational tools can be applied to analyse signals carried by these seismic waves from their source (e.g. guided waves). Several projects exist to study subduction dynamics in such a way from a seismological perspective. Any interested students are encouraged to contact the supervisor for more information.

Such projects are primarily computer based, and prior experience with Matlab or similar programs would be advantageous. Opportunities to assist in collecting seismic data in the field may also arise during the course of a project.
