Schematic model of Yellowstone’s subsurface magmatic sill complex based on seismic data collected in 2020

Schematic model of Yellowstone’s subsurface magmatic sill complex based on seismic data collected in 2020. The presence of magmatic sills with higher amounts of melt—about 28%—compared to their surroundings is revealed by data collected from a dense deployment of about 650 3-component (capable of measuring vertical and horizontal motion) seismometers in Yellowstone National Park during August-September 2020.
