Summary

3D shear-wave velocity model of the Bolivian Orocline (BO) from the joint inversion of ambient noise tomography and two-plane wave tomography

Description

Name BO.ANT+TPWT.Ward.2016
Title 3D shear-wave velocity model of the Bolivian Orocline (BO) from the joint inversion of ambient noise tomography and two-plane wave tomography.
Type 3-D Tomography Earth Model
Sub Type Shear-wave velocity (km/s)
Year 2016
 
Short Description   The model incorporates seismic data from an earlier ambient noise tomography study (Ward et al., 2013) with two-plane wave tomography to image the shear wave velocity structure of the Bolivian Orocline (BO) from the joint inversion of ambient noise and earthquake generated surface waves.

Depth Coverage 0 to 200 km (bsl)
Area The Bolivian Orocline (latitude: 12°S/19°S, longitude: 76°W/65W°)
 
Data Set Description [[Ward et al., (2016)] The dataset includes the absolute S-wave velocity structure across the Bolivian Orocline (BO) from the joint inversion of ambient noise tomography and two-plane wave tomography.

Two-dimensional horizontal S-wave velocity maps.
Two-dimensional horizontal S-wave velocity results for two depth slices shown as perturbations from the starting model (starting model values for each depth slice is constant for the same depth slice shown). Red contour shows Slab 1.0 contours (Hayes et al., 2012) for each corresponding depth slice. Green (circles) earthquake locations are from Kumar et al. (2016) and blue (circles) earthquake locations are from Instituto Geofísico del Perú.
