The Andean range stretches for thousands of kilometers from Patagonia to Venezuela and its recent tectonic evolution results from the ongoing subduction of the Nazca plate. Less studied than the subduction mega earthquakes, several M>7 continental earthquakes did affect the Andean human settlements since the Pre Incaic period. Although neglected in terms of archaeoseismic or neotectonic studies, the impacted regions display exponentially growing megacities, highly exposed to seismic hazards. In this study, we focus on investigating crustal deformation along newly described fault systems, in a seismically active urban setting (in Peru and Ecuador). High resolution satellite images, geodetic data, georadar and field studies provide striking examples and evidences of the ongoing tectonic deformation that can be the longer-term Quaternary geomorphic record. We focus here on the Quito and Ibarra regions in northern Ecuador, and on Arequipa and Cuzco regions in southern Peru.
