Description
| Name | TX_EF_2020-S | ||
| Title | S-velocity model of the Eagle Ford of southeastern Texas from joint inversion of Ambient Noise Tomography and P to S Receiver Functions | ||
| Type | 3-D Tomography Earth Model | ||
| Sub Type | S velocity perturbation (%) and S velocity (km/s) | ||
| Year | 2020 | ||
| Short Description | TX_EF_2020-S provides estimates of shear velocity for southeastern Texas focused on the Eagle Ford Shale Play. The model uses passive source methods of ambient noise tomography and P to S receiver functions to jointly invert for shear velocity structure. The data is derived from recent TexNet broadband seismic deployments designed for earthquake monitoring and structural characterization. |

| Depth Coverage | 0 to 100 km | ||
| Area | Eagle Ford of southeastern Texas, Longitude: 99˚W to 95˚W in 0.05˚ increments, Latitude: 27˚N to 31˚N in 0.05˚ increments (map) | ||
| Data Set Description | Seismic data was obtained from IRIS for network codes: 2T [Part of TexNet; doi:10.7914/SN/TX], 4F [North Texas Earthquake Study: Venus (Johnson County), TX; doi:10.7914/SN/4F_2015], IU [Global Seismograph Network – IRIS/USGS; doi:10.7914/SN/IU], N4 [Central and Eastern US Network; doi:10.7914/SN/N4], SS [station DAL, no doi], TA [USArray Transportable Array; doi:10.7914/SN/TA], TX [TexNet; doi:10.7914/SN/TA], US [United States National Seismic Network; doi:10.7914/SN/US], X4 [Gulf of Mexico Basin Opening; no doi], X9 [Dallas Earthquake Swarm; doi:10.7914/SN/X9_2008], and ZW [North Texas Earthquake Study: Azle and Irving/Dallas; doi:10.7914/SN/ZW_2013]. | ||
| Model Resolution | The models have 1.2-km node spacing in all directions. Unmasked regions correspond to strong semblance (recovery of checkerboard patterns) for features of 20-km width. Depth resolution is generally best from the surface to 20 km depth. |
