Análise da exposição a movimento de massa com uso de ARP – Aeronave Remotamente Pilotada na comunidade São José do Jacó, Natal, Rio Grande do Norte, Brasil

Abstract

Mass movements are phenomena that affect people living on slopes or places that have this configuration. The anthropic occupation in these areas, carried out without the proper territorial planning, puts these people in a situation of exposure to risks, being able to cause material and human losses in case of disasters. The present work aims to analyzing the levels of exposure to mass movements in the São José do Jacó community, Natal/RN, from environmental exposure indicators. The chosen study area is one of the risk areas established by the Municipality of Natal, as well as having already suffered some landslides and interdictions of homes with risk of collapse in 2014. The community of Jacó has relief with high slopes on the slopes. Based on concepts and an environmental characterization of the area, evaluation sheet of exposure to mass movements were elaborated and applied, using a methodology adapted from Guerra et al. (2009) and Alheiros (1998). In addition, photos in the area were taken with the aid of a Remotely Piloted Aircraft - ARP. The results of the analyzes of the exposure to the mass movement risk were divided by sectors, which in the majority presented a level of exposure to very high mass movements, which creates an alert for the responsible authorities of the necessity of creating measures mitigation and risk management, not only in the community of Jacó, but also throughout Natal.
