Geodynamic modeling helps to elucidate magma formation and movement below Yellowstone Jamie Farrell Yellowstone is one of the most seismically active areas in the western United States. In addition to seismicity, Yellowstone experiences active ground deformation mainly concentrated at or near its caldera, a massive basin-shaped collapse structure formed shortly after the last explosive volcanic eruption 630,000 years ago. These characteristics, along with Yellowstone’s hydrothermal features, are evidence of an active magma reservoir underlying the caldera. Previous studies indicated the accumulation of partially molten rocks (melt) beneath Earth’s crust in Yellowstone (1–4). However, their origin and interaction have been elusive.
