Currently, we're using surface waves from earthquakes (Schutt and Dueker, 2007, in press) and ambient noise to image the crust and upper mantle in the Yellowstone region. Using the group and phase velocities from Rayleigh waves, along with crustal thickness constraints (Yuan et al, 2007, in prep.), we inverted for a high resolution shear velocity model for the Yellowstone Hotspot track. We use this model to interpret past and present magmatic processes in the region.
