We investigate deformation of the Earth's crust due to earthquakes and volcanoes.
Measuring deformation that occurs between earthquakes constrains how much elastic strain accumulates in the crust and helps constrain future earthquake hazard. Similarly, accumulation of magma in crustal reservoirs causes the earth's surface to swell, critical information for forecasting eruptions. In both volcanic and tectonic environments we combine measurements with physics-based models of the relevant processes to better understand these systems.
