Summary

3D shear-wave velocity model of the Altiplano-Puna Volcanic Complex (APVC) and the Puna Plateau from the joint inversion of ambient noise tomography and receiver functions.

Description

Name APVC+Puna.ANT+RF.Ward.2017
Title 3D shear-wave velocity model of the Altiplano-Puna Volcanic Complex (APVC) and the Puna Plateau from the joint inversion of ambient noise tomography and receiver functions.
Type 3-D Tomography Earth Model
Sub Type Shear-wave velocity (km/s)
Year 2017
 
Short Description   The model incorporates seismic data from an earlier ambient noise tomography study (Ward et al., 2013) to image the shear wave velocity structure of the Altiplano-Puna Volcanic Complex (APVC) and the Puna Plateau from the joint inversion of surface wave dispersion and receiver functions. Both broadband and short-period instruments are used to calculate the receiver functions used in the production of this model.

Data Set Description [Ward et al., (2017)] The dataset includes the absolute S-wave velocity structure across the Altiplano-Puna Volcanic Complex (APVC) and the Puna Plateau from the joint inversion of ambient noise tomography and receiver functions.

cross-sections through the shear-wave velocity model
(a–e) West-east cross-sections through our shear-wave velocity model with the locations shown in the lower right corner. Blue triangles show Holocene age volcanism of the Central Volcanic Zone (CVZ), gold circles show known ignimbrite eruption calderas, inverted red triangles show INSAR measured vertical surface deformation centers, and white lines are the Moho. Vertically exaggerated (3:1) unfiltered topography is colored by the magnitude of the Bouguer gravity anomaly at that location. The labels APMB (Altiplano-Puna Magma Body), LMB (Lazufre Magma Body), CGMB (Cerro Galan Magma Body), IMB (Incahuasi Magma Body), and IBMB (Incapillo-Bonete Magma Body) correspond to imaged magma reservoirs discussed in the main article.
