Introduction
The Central California Seismic Project model (tentatively called "CCA") is a 3D velocity model comprised of the results of the full 3D tomographic inversions done by En-Jui Lee. This technique was first introduced in CVM-S4.26, which is a SCEC southern California velocity model.
Coverage Region
The CCA model covers:
-120.0000, 33.3999
-122.9500, 36.6000
-118.2962, 39.3548
-115.4454, 36.0403
The map to the right shows the bounding box of this new velocity model.
The grid spacing within the model is 500m and we use trilinear interpolation in between the grid points. The model covers depths down to 50km.
Iterations and Data Files
Presently, four iterations have been done on Mira. The source data files are located in /home/scec-01/enjuilee/work/CCA_ASCII and can be accessed on intensity. The script "make_data_files.py", included within the CCA source code, automatically retrieves these files from the USC server and builds the binary float files used by the CCA model.
Stand-alone Plots
Below are three horizontal slices generated from UCVM that show the fourth iteration CCA model at the surface level (0km depth), 500m depth, and 2km depth.
