dc.description.abstractenIn a large part of South America, slow landslides are triggered by extremehydrometeorological conditions leading to, for instance, Rainfall-InducedLandslides – RILs. These RILs are common in urban areas and have a negativeimpact on the population and infrastructure development. Despite theirimportance, these events are little understood. We aimed at understandingthe spatial distribution of RILs in the urban zone of Temuco, Chile (38.8°S,72.6°W). The area has the typical hydrometeorological conditions of southernChile. We conducted our assessment with a temporal analysis of shallowdeformations, obtained by synthetic aperture radar interferometry (Sentinel1 A/B). These shallow deformation rates were compared with satelliteprecipitation data (CHIRPS product) and electrical resistivity tomography(ERT). We identified active RIL-prone zones with deformation rates greaterthan 60 mm during the period 2014 to 2017, supporting theories ofhydrometeorological control. Slow movements were observed in volcanicsoils, suggesting the influence of their geotechnical characteristics. Our resultscan be extrapolated to the southern Andes (35°S-43°S), where a large numberof volcanic-sedimentary units are susceptible to RILs. Finally, integration ofour multidisciplinary approach will facilitate understanding of the local RILdynamics, allowing a better risk management to decision-makers in SouthAmerican and other developing countries.
