Reply to the comment by R. A. Astini and F. M. Dávila on “The West Andean Thrust, the San Ramón Fault, and the seismic hazard for Santiago, Chile”
Abstract
We have proposed earlier a new tectonic model for the
evolution of the Andes mountain belt as a bivergent orogen.
Here, to reply to a comment by Astini and Dávila [2010], we
discuss briefly the protracted diachronic evolution (over tens
of million years) by propagating deformation at the largescale
(over 102–103 km), its influence on basin formation
in the back‐arc region (retroarc foreland basin), and the
mechanical implications of the bivergence in the tectonics of
the fore‐arc region, particularly the possible effects of the
underthrusting of the coastal crustal‐scale rigid block (the
Marginal Block) beneath the West Andean Thrust
