This page documents the NC1D velocity model, created as part of the preparations for Study 24.6.
Summary
This model was created by creating a 1D representation of the (unmodified) Sierra gabbro region in SFCVM v22.1. It is intended for use in the northeastern parts of California, a region covered by few CVMs. It was created by extracting a 1D profile from the Sierra gabbro region and then manually creating a 1D model which closely approximates this profile. Note that the Sierra gabbro region as specified in SFCVM v22.1 has high near surface velocities (around 3500 m/s), so this is reflected in NC1D as well.

Plots
Vertical profile of NC1D model.
Horizontal cross-sections. The NC1D model is used in the northeastern portion of the volume; you can see how it is similar to the Sierra gabbro region.
