Movimentos gravitacionais de massa na literatura geomorfológica: os escorregamentos no meio urbano, em perspectiva conceitual

Abstract

Landslides are phenomena that, although they can occur naturally, have become increasingly frequent in urban areas due to changes caused by the occupation of these environments. Particularly in underdeveloped countries with late urbanization, the growth of cities generally occurs without planning and efficient public policies for territorial management. The geomorphological literature is rich in information related to the conceptualization of landslides, as well as in the definition of their typifications. Even so, there are still gaps that allow for a conciliatory review of knowledge that helps in the recognition, identification and evaluation of landslides, as well as the cause and effect relationships between these phenomena and urbanization. With the aim of presenting contributions regarding this discussion, this article presents the main technical and scientific definitions of landslides, their typology and conditions for their occurrence, with special attention to the Brazilian urban context.
