We observed Rayleigh-wave apparent anisotropy near structural boundaries

We used spectral element numerical wavefield simulation to reproduce apparent anisotropy near major velocity contrast

We used mode coupling theory and locked mode approximation to confirm scattered body wave cause longer wavelength velocity variation corresponding to observation.

We constructed a 3D shear wave velocity model for the Salt Lake Valley from joint inversion of Rayleigh wave ellipticity and phase velocity 

Our study demonstrates the potential of basin imaging based on earthquake coda interferometry.  

We use multiple local seismic event stacks to estimate pre‐critical Moho reflection PmP and SmS arrivals.

Average Poisson's ratio of crust and Moho depth are estimated using Moho reflection arrivals.

This study shows that local seismic events, including induced events, can be utilized to estimate properties and structure of the crust
