The project objectives are first, transition the 1D coda methodology to a full 2D capability, including both P-coda and S-coda, including the ability to account for frequency-dependent phase blockage, as well as 2D variations in peak envelope velocity and site-transfer corrections second, improve upon the way amplitude measurements are made and tie to an absolute scale. Existing data holdings are being leveraged at both institutions and also new results used that stem from local background coda models, earthquake source scaling studies, and more-sophisticated scattering models in the literature.
