Modeling of highly anisotropic crust and application to the Altiplano-Puna volcanic complex of the central Andes

  title={Modeling of highly anisotropic crust and application to the Altiplano-Puna volcanic complex of the central Andes},
  author={Mark Leidig and George Zandt},
[1] The Altiplano-Puna volcanic complex (APVC) is located in the central Andes and covers an area over 50,000 km. The style of volcanism is predominately caldera-forming ignimbrite eruptions active between 10 and 1 Ma. Chmielowski et al. [1999] used teleseismic events, recorded from seven portable broadband seismic stations deployed in the APVC, to identify a 1-km-thick very low-velocity zone at a depth of 19 km. Based on the correlation with surface volcanics, the extremely low shear… CONTINUE READING
