Sumario:[EN] This communication presents the formulation and first steps of an Industrial PhD project, developed in the frame of the “Kuk ahpán” project (Spanish National R&D Plan, 2019-2022) that aims to understand, monitor and model tectonic processes at the lithospheric scale in Central America. For this purpose, an international team from six countries (Nicaragua, Costa Rica, El Salvador, Guatemala, Norway and Spain) works integrating research in diverse geophysical techniques and engineering, with the aim of updating Seismic Risk Maps for the Region, a critical input for Safety and Construction Codes. The proposed PhD project is framed on the research and development of technologies to prevent natural and induced geological risks that affect cities and infrastructures in highly vulnerable countries, using the DInSAR (Differential Interferometry with Synthetic Aperture Radar) technology optimized by the startup Detektia Earth Surface Monitoring in collaboration with Universidad Politécnica de Madrid. Differential Synthetic Aperture Radar Interferometry is a technique based on the processing and analysis of long series of Synthetic Aperture Radar images. This technology provides records (since 1992) and up-to-date movements on any surface anywhere in the world without the need for ground instrumentation, with accuracies about 1 mm/year (velocity). In this context satellite radar provides valuable information on very large areas that complement the field work and in-situ instrumentation. The methodological approach starts by integrating DInSAR data with geophysical and geodesical data such as bathymetry, geomagnetism, gravimetry, seismic profiles, GNSS series… to fully map the Swan fault over Honduras and Guatemala. We use this technology to address the seismic risk over the fault and nearby areas. Then, on a second step, we will apply this seismic risk assessment (including natural and anthropogenic hazards) in prioritized cities and critical infrastructures in Central America.
