3D shear-wave velocity model of the Alaskan Cordillera from the joint inversion of ambient noise tomography and receiver functions.
|Title||3D shear-wave velocity model of the Alaskan Cordillera from the joint inversion of ambient noise tomography and receiver functions.|
|Type||3-D Tomography Earth Model|
|Sub Type||Shear-wave velocity (km/s)|
|Short Description||The model incorporates seismic data from an earlier ambient noise tomography study (Ward, 2015) along with new Transportable Array data to image the shear wave velocity structure of the Alaskan Cordillera from the joint inversion of surface wave dispersion and receiver functions.|
