| Data Set Description | This three-dimensional shear wave velocity model is based on a full waveform ambient noise tomographic method using the extracted empirical Green’s function between 8 to 40s. The data are collected from all the available broadband recordings of ambient noise around and within the Northern Mississippi embayment (33°N – 38°N, 94°W – 86°W) from 1990 to 2018, including existing stations of the New Madrid Cooperative Seismic Network (NM), EarthScope Transportable Array (TA), and the Ozarks-Illinois-Indiana-Kentucky (OIINK) and the Northern Embayment Lithosphere Experiment (NELE) EarthScope FlexArray experiments. Data were obtained for 277 stations with a total of 14,916 pairs of vertical-vertical cross-correlations from the permanent and temporary networks (network codes: 3E, 6E, 7F, AG, IU, KY, N4, NM, TA, XO, Y8, YZ, ZL, and ZN). The model presents a well-resolved, 3D image of mid-crustal velocity structure in the central United States. |
