26-125 Active deformation of the Andean Plateau, FLATSIM and ScarpLearn Code

Mission

Abstract

The Altiplano region in the Central Andes is a natural laboratory for studying tectonic and geomorphological processes in continental highlands. Its active deformation and flexural rigidity are key to understanding crustal dynamics in a subduction context and the long-term evolution of Andean landscapes. Yet, the mechanisms driving this deformation and the spatial–temporal variations in fault activity or lithospheric rigidity remain poorly constrained. This PhD will address these questions by combining innovative approaches: Holocene geomorphology analysis on Pléiades DEM with ScarpLearn (Deep Learning), interpretation of continental-scale FLATSIM InSAR data, and the integration of nested spatial and temporal scales thanks to TCN dating of morainic markers (~4500m high).

Objectives

1.Characterize active deformation of the Altiplano plateau through Holocene geomor-phological markers and processes, identifying fault scarps and ...
