Interests

Earthquakes are a violent manifestation of the tectonic movement of the earth's tectonic plates, and affect millions of people annually, yet in spite of this we still do not fully understand how they start. To investigate the nucleation of earthquakes I use a combination of experiments, modelling, theory and fieldwork to develop a model of nucleation that is faithful to natural faults. I am interested in determining the role of natural fault architecture and structure in earthquake nucleation.

PhD- Laboratory earthquakes

 My primary PhD focus is to understand how fault zone architecture and the inherent heterogeneity of natural faults exerts primary control on the propensity of natural fault to nucleate earthquakes. To do this I conduct experiments on roughened blocks of rock to simulate the observed roughness of natural faults, which is then compared to a new theoretical model of nucleation which has been developed during the course of the PhD (Harbord et al. In Press). I am currently exploring the general applicability of this theory by utilising a variety of crystalline and granular rocks. I am also extrapolating results by modelling the stress distribution of natural fault surfaces.

I have also been involved in researching the mechanical strength of serpentinite gouges at high temperature to understand their role in weak faulting in collaboration with researchers at INGV in Rome.
