CCA

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 grid spacing within the model is 500m and we use trilinear interpolation in between the grid points.
