Velocity models used for migration in "Bedrock Offset Across the Wasatch Fault in Salt Lake City, Utah, from Teleseismic Converted Phases and Its Geologic Implications"

The files sta040_EllRF_l4.max.txt and sta049_EllRF_l4.max.txt (version 1 of this repository) specify the velocity models beneath stations sta040 and sta049 that were used for the receiver function migrations in Kim et al. (2026). Each line after the first (header) line in these files has the depth in km to the bottom of a uniform velocity layer followed by the P-wave velocity (Vp) and S-wave velocity (Vs) of the layer in km/s. These velocity models are identical to the ones displayed in Figure 1 of Kim et al. (2026) except that, for the migration, the velocities where Vs > 1.5 km/s are replaced with half-space continuations of the velocities in the overlying layer. The purpose of the velocity model modifications is to prevent bias in the migrated depths to the R2 interface by using only the parts of the models above this interface, which Kim et al. (2025) define as the depth where Vs increases to 1.5 km/s or greater. Correction After the online publication of Kim et al. (2026), we discovered that the modification to the P-wave velocity model for sta049 did not remove the R2 velocity discontinuity as we had intended. The halfspace velocity for the model that we used for the migration was 3.305 km/s, but should have been 2.255 km/s. The corrected model is in the file sta049_EllRF_l4.max.corr.txt. Fortunately, the mistake in modifying the velocity model for sta049 had only a small effect on the results that was well within the uncertainties. Below is a revised version of Table 1 in the paper: Table 1Measurements of R2 Elevations and Vertical Displacement (m) R2 Measurement Mean Using Maximum Probability Models from Figure 1d,e Standard Deviation (from Fig. S3) Footwall (east side) elevation 1112 73 Hanging-wall (west side) elevation 247 275 Elevation difference across the fault 865 288 The only two numbers in this table that changed are the mean hanging-wall elevation and the mean elevation difference across the fault. The other effects of the velocity model correction on our results are as follows: (1) The rounded difference in R2 elevation between the footwall and hanging wall changes from 810 +/- 290 m to 860 +/- 290 m; (2) The minimum apparent fault dip in the top 1100 m changes from 79 (with a range of 74 to 82) deg to 80 (range 75 to 83) deg; and (3) The minimum true fault dip in the top 1100 m changes from 81 +/- 3 deg to 82 +/- 3 deg. (The error bars for the revised minimum dip are an average.) Note that our estimated age of the East Bench fault, 0.7-1.4 Ma, remains unchanged. References Kim, H.J., F.-C. Lin, J.C. Pechmann, C.L.
