(A) RMS shear wave velocity computed from the eight velocity models spanning the southern U.S. (SUS), along with our average model (SUSavg). (B) Comparison of SUSavg with the average model for the other domains of the U.S.: WUS—Western U.S.; CUS—Central U.S.; and EUS—Eastern U.S., as well as the 1D reference models, ak135 and PREM.
