Resumen en español

Mass movements are the product of a progressive reduction of strength of slope geomaterials by human actions or natural processes, such as weathering, and triggered by external factors like rainfall or earthquakes. These events have demonstrated throughout history its destructive capacity, causing huge human and economic losses, especially in tropical and mountainous terrains, such as the Aburrá Valley. For this reason new studies on rainfall forecasting, real-time monitoring and the definition of critical rainfall thresholds have become essential tools for the implementation of early warning systems.
