3D rendering of the shear-wave-speed anomaly below Yellowstone

3D rendering of the shear-wave-speed anomaly (ɗVS) below Yellowstone. Regions of strongly reduced shear-wave speed most likely indicate volumes of partially molten crust. Iso-surfaces (surfaces of constant ɗVS) are shown in increments of 5%. To accentuate detail, the anomaly is sliced along a vertical plane (shown in map view as a white dashed line) that transects Yellowstone Caldera.
