Anatomy of the Andean subduction zone: three‐dimensional density model upgraded and compared against global‐scale models

SUMMARY We present an upgraded version of a previously published 3‐D density model of the Andean subduction zone between 18°S and 45°S. This model consists of 3‐D bodies of constant density, which geometry is constrained by independent seismic data and is triangulated from vertical cross‐sections. T...
