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.
