Sierra Foothills 1D
From SCECpedia
Jump to navigationJump to searchThis 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.
