Data Services Products: EMC-DNA10-S S-velocity model for the western US integrating body- and surface-wave constraints

Summary

DNA10-S model, Obrebski, Allen, Pollitz & Hung (2011), integrates teleseismic body-wave traveltime and surface-wave phase velocity measurements into a single inversion to constrain the S-wave velocity structure beneath the western US.

Description

Name DNA10-S
Title S-velocity model for the western US integrating body- and surface-wave constraints
Type 3-D Tomography Earth Model
Sub Type S velocity perturbation (%)
Year 2010
Short Description   The DNA10-S model integrates teleseismic body-wave traveltime and surface-wave phase velocity measurements into a single inversion to constrain the S-wave velocity structure beneath the western US (from the Pacific coast to ~100° W, from Mexico to Canada).

Data Set Description [ Obrebski et al. (2011)] he station distribution that used in this study covers all the major magmato-tectonic features of the active western United States plus the westernmost part of the stable cratonic United States. This includes more than 1200 stations from the USArray transportable array, regional seismic networks, and temporary seismic deployments. Data were recorded from 2006 January to 2010 January. Relative traveltimes of teleseismic body waves (S and SKS) obtained from about 162 earthquakes, and surface wave phase velocity measurements from 167 eartqhuakes were used to constrain the model.
