Summary

3D vertical shear-wave velocity model of the Cascadian forearc from the joint inversion of ambient noise dispersion and receiver functions

Description

Name Cascadia_ANT+RF_Delph2018
Title 3D vertical shear-wave velocity model of the Cascadian forearc from the joint inversion of ambient noise dispersion and receiver functions.
Type 3-D Tomography Earth Model
Sub Type Shear-wave velocity (km/s)
Year 2018
 
Short Description   This model was created from the joint inversion of ambient noise Rayleigh waves dispersion measurements (8-50 seconds) and adaptive CCP-derived receiver functions (see Delph et al., 2015, 2017 for details of methodology; Delph et al., 2018 for details of this model).

Data Set Description This model contains data from roughly 1000 broadband seismic stations distributed throughout the western United States. Time period of data is 1993-1994, 2005-2016.

Map slices and cross sections
Map slices (left) and cross sections (right) through shear wave velocity model. Red lines correspond to slab model of (McCrory et al., 2012). While line in cross sections corresponds to inferred Moho (dashed where uncertain). Red triangles: Holocene volcanic centers; Black triangles in cross sections: seismic stations used in receiver function analysis.
