Geomorphological Hazards in Costa Rica: Upper General River Basin

In tropical countries as Costa Rica, landslides and floods are triggered by intense precipitation events, weathering, rock control, seismicity, morphology and the slope angle. The recurrence and magnitude of these processes provoke economic losses and casualties in the communities of the Upper General River Basin in the center-south of the country. The current work determines based on morphogenetic and morphometric maps, the higher susceptibility zones affected by these geomorphological hazards. In the past events such as the Buenavista earthquake (1983), hurricanes Joan (1988), César (1996), tropical storm Alma (2008), and hurricane Nate (2017) caused human losses and serious economic damage to vital lines (roads, electric lines, and aqueducts) as well as in the agricultural secto
