Estimación de la subsidencia en torno a la traza de la falla de San Ramón Chile, mediante la técnica SBAS DInSAR usando imágenes TerraSAR-X

Chile is one of the countries with highest seismicity in world and affected by three types seismogenic sources; interplate, intraplate superficial or cortical intraplate. In this context, eastern sector city Santiago, capital Chile, Falla San Ramón (FSR) located. It a source, which threatens its habitants various economic activities that are located sector, geological hazards such as earthquakes mass removals. relation to above, study aims identify establish subsidence areas longitudinal strip Santiago mountain front impact on neighboring communes FSR trace during years 2011 2017. To do this, The DInSAR technique was used Small Baseline Subset (SBAS) algorithm through time series images from TerraSAR-X (TSX) satellite. results show zones, average displacements ranging -13.11 mm +9.89 mm, an annual speed rate -2.19 +1.65 mm/year.
