Pressure and Stress in the Earth

Pore pressure, stress, and deformation are coupled. Their interaction controls earthquakes, submarine landslides, and the morphology of continental margins. We explore the coupling between rock deformation, fluid migration, and pore pressure to understand these processes. Our work illuminates controls on earthquake behavior, the controls on hydrocarbon and CO2 storage, how to drill stable wells, when and where landslides occur, and how permafrost melts. We are now coupling complex material models with three-dimensional whole earth models to understand these processes.
