Dynamic Simulations of Plumes used in Sensitivity Tests (image) University of Texas at Austin, Texas Advanced Computing Center Share Print E-Mail Caption Dynamic simulations of plumes used in sensitivity tests. The plumes are symmetric about the vertical axis at x = 0. For each plume, the excess temperature is shown on the left and the reduction in shear velocity ?VS relative to the Preliminary Reference Earth Model is shown on the right. The plume structures R1a, R1b, and R1c are snapshots of the same dynamic simulation at 45 Myr, 55 Myr, and 175 Myr, respectively. Credit Maguire et al.
