GeoRED, the Spanish acronym for “Geodesia: Red de Estudios de Deformación” or “Geodesy: Deformation Studies Network,” is a research, innovation, and development project based on space geodesy, which takes a multifaceted approach to understanding the geodynamics and tectonics of northwestern South America with an ultimate goal to reduce the risks associated with active plate boundaries. Space geodesy nowadays is an indispensable tool to determine interplate and intraplate continental deformation and to achieve a better understanding of the seismic cycle. In this article, we highlight efforts in Colombia to create a geodetic infrastructure that is composed of 108 continuously operating permanent stations and 382 field stations that will aid in determining the present crustal deformation in the country. So far this has led to a much more detailed and quantified picture of the northward migration of the North Andean Block (NAB), the process of strain partitioning and plate coupling in the Nazca plate subduction zone, and the rate of boundary-normal shortening and boundary parallel displacement in the Eastern Cordillera
