英文摘要: We evaluate Rayleigh wave group velocity dispersion (5-40 s) around the Yellowstone Volcano Field with ambient noise tomography, measured from vertical component noise correlation functions. We include broadband data from 239 seismic stations (1999-2012), including USArray's Transportable Array and the Noise Observatory for Imaging the Subsurface beneath Yellowstone (NOISY). Short-period (<13 s) group velocity anomalies are imaged for the Bighorn Basin (∼25% slow) and Range (∼20% fast), and the Yellowstone Plateau (∼10% fast). Beneath the Yellowstone caldera, Rayleigh wave group velocities are ∼25% slower than the regional average with slow anomalies (<-15%) observed from 5 to 24 s. These values are consistent with a magmatic body being heated from below by an underlying plume. © 2014. American Geophysical Union. All Rights Reserved.
