Community Velocity Model - SCEC 5
CVM-S5 is an improved version of the CVM-S4 velocity model which includes full 3D tomographic improvements to the SCEC 4 velocity model as well as an optional GTL implementation.
Density Based on Vs
According to Po Chen:
"The Vs-density relation was obtained from Table 1 in Brocher 2005. In that table, the 3rd column is Vs and the 5th column is density. So I did a regression using data from these two columns and obtained a polynomial relation for Vs-density. Those numbers in that data file are the coefficients of the polynomial."
The actual polynomial is:
1.2948318548300342 + 1.2550758337054457 * vs - 0.51231936640441489 * vs2 + 0.051962399479341816 * vs3 + 0.015600987888334450 * vs4 - 0.0024189659303912917 * vs5
