Fig. 3 — (A) Variation of median phase velocity and attenuation coefficient with period for the whole study region. The upper and lower bounds represent the percentiles 75 and 25, respectively. (B) Regionalized analysis of attenuation coefficient and phase velocity values. The absolute values of phase velocity change, but always follow the same increasing pattern, while the attenuation coefficients are different depending on the tectonic setting. USArray clusters 3, 4, and 5³² are shown for comparison.
