Data Services Products: EMC-TX2019slab A global P and S mantle model incorporating subducting slabs

Summary

TX2019slab provides shear velocity perturbations with respect to the averaged TNA/SNA model and compressional velocity perturbations with respect to the AK-135f model with the mean from the individual layers removed. The grid is not representative of the block size used in the inversion.

Data Set Description
Supplemental Information Zip bundle contains 22 gridded files for P and S velocity perturbations at each depth range, separately. In each gridded file, three columns are corresponding to latitude, longitude, and velocity perturbation in percentage. The 22 depth ranges are provided in “layerdepth” file. In the “relocated_eq_list” file, the latitude, longitude, depth, and origin time shift are shown for the relocated earthquakes.

model TX2019 at various depths
Lateral velocity variations in model TX2019slab at representative depths. Each row corresponds
to the model at a particular depth, and the two columns show P wave (left) and S wave (right)
models, respectively. The color scales change for each plot according to the amplitude (X) labeled
at the bottom right corner.
