Mass movement in the neighbourhood of Veneza, São Domingos municipality - Cape Verde
| Resumo: | Due to its geographic location and climate, Cape Verde is subject to a number of natural hazards, such as drought, desertification, floods, and earthquakes. The present work is a study carried out in the neighbourhood of Veneza, São Domingos Municipality, with the focus being on the dynamic processes of the landscapes, in particular mass movements. Its objective is to identify the different types of mass movements that occur in the area and to elaborate a map of distribution of this process in this locality. The methodology used initially consisted of researching bibliographic and cartographic documents, then proceeding with fieldwork. This focused on direct observation in the field of the types of mass movements that occurred, factors that influenced these processes, and their inventory. Finally, we proceeded to analyse and process the collected data and prepare maps. The results obtained, mainly from on-site observations, show that the most frequent mass movements in the studied area are dry debris flow and rockfalls. These occur either by free-fall or by jumping and rolling, and in some cases they pose an imminent risk to the population. |
