YS-Svh-W23

The model integrates the data from a temporary 650-element 3-component dense nodal array throughout Yellowstone National Park between August 17 and September 21 2020, 37 permanent stations of Yellowstone seismic network, and 188 stations from USArray Transportable Array (TA) and regional networks across Idaho, Wyoming, and Montana that were operating during 2007–2010 for ambient noise cross correlation. The retrieved Rayleigh and Love wave dispersion curves are then jointly inverted through a one-step ray-tracing-based inversion scheme that takes into account the off-great-circle wave propagation and avoids potential inconsistency in space introduced by independent inversion/regularization processes between different periods.
