Overview

CVM-SI i5 map plot of Vs at depth 0m.

CVM-SCEC Improved(CVM-SI), is a 3D seismic velocity model based upon CVM-S with changes. Perturbations have been applied to this model as a result of iterations of inversion simulations by Chen P. et al (y????). This improved model has been imported into UCVM and is referenced with the model label "cvmsi".

The velocity model is a Fortran code and associated files that are downloaded, compiled, and run locally. The user queries the models by creating an input file of latitude, longitude, and depth values, and the model returns Vp, Vs, and density at each of those points.


Iteration 5

The latest version of this model is iteration 5.

Map and profile plots of version I5.


Differences with CVM-S4

The plots at right show a difference map of i5 - i0, followed by a plot of the starting model, i0, for reference.
