CLASSIFICATION OF LANDSLIDES OCCURRED IN MARCH 2011 IN THE SERRA DA PRATA, STATE PARANÁ

Abstract

The landslides are characterized by natural processes of evolution of slopes, and therefore the landscape as a whole. According to the speed and composition of the material moved down slope, receives different denominations. Processes are triggered by a number of natural factors, however, can be leveraged by human action. In Brazil, the landslides of great magnitude, when occurring in the occupied areas, gain context of natural disasters, since, causing considerable damage socioeconomic, and sometimes with fatalities. Studies of these phenomena in the country increased from the mid-twentieth century, after records of catastrophic events. In recent years, occurred in the Vale do Itajai, Santa Catarina (2008), in the mountainous region of Rio de Janeiro (2011) and on the coast of Paraná (2011), had large proportions. The latter left a trail destruction and significant harm to the local population. In this context, this case study, based on query specific benchmark, cartographic material, and especially field analysis, is proposed to classify the event occurred on the coast of Paraná State, specifically in relief compartment called Serra da Prata, of appropriately, and demonstrate aspects related to changes caused by this phenomenon.
