The hundreds of earthquakes that are felt around the world every week are a constant reminder that the Earth is a dynamic place. Appreciating and forecasting the hazard from earthquakes requires an understanding of the stresses that drive faults to fail and what happens to the rocks cut by a fault during slip. These aspects of fault mechanics can't be addressed directly through seismology. My research uses field observations of faults to investigate the earthquake source directly. What can we learn from the rocks themselves? The goal is to use high-resolution digital field data (ground-based LiDAR, differential GPS, structure-from-motion photogrammetry) combined with microstructural work (SEM, TEM, EBSD and microprobe) and statistical and numerical models to show how fault geometry, composition and fluid transport properties control faulting, and more broadly deformation throughout the brittle crust.
