SUMMARY:

.The risks of disasters are accentuated due to urban growth coupled with the lack of territorial planning, social inequality, environmental degradation and several other factors that contribute to the occurrence of this type of event. In this perspective, two cities in the Northeast can be highlighted: Natal (RN) and São Luís (MA) which have recurrent cases of risks of mass movements in the districts Mãe Luíza - Natal and Vila Embratel - São Luís and also cases of flooding only in Vila Embratel. However, it is important to note that each area has physical-natural aspects distinct example, in St. Louis predominance trays and dissected trays (CPRM, 2018), while in Natal, fixed and mobile dunes formations are quite significant ( CPRM, 2016). However, the natural configurations and also the social characteristics of both areas are not an impediment to the occurrence of risks, on the contrary, this accentuates the possibility of these events occurring. Thus, this research seeks to answer: How do disaster risk indicators on a local scale help in identifying the degree of risk considering the dimensions of exposure and social vulnerability in an urban area? Whereas the risk is determined by the product of exposure and social vulnerability, the hypothesis to be validated part of the following statement: The degree of risk can be high or low and the element that will determine this value is the exposure and social vulnerability. Although a given area is very exposed and not very vulnerable, or even little exposed and very vulnerable, the risk will remain high. Therefore, it is not related only to exposure to danger or just to the social characteristics of the population. The risk depends on both dimensions and can be high, even though their levels are inversely proportional. To validate or refute this hypothesis, the general objective of the research is to produce disaster risk indicators on a local scale based on the dimensions of exposure and social vulnerability in the Vila Embratel (São Luís - MA) and Mãe Luíza (Natal - RN) neighborhoods. Thus, the procedures of this study were divided into three stages: the first deals with the risk exposure of each area where two indices are measured: Exposure to Mass Movement (IEMM) and exposure to flood (IEI). This step is discussed on a methodology that will give more detail to the Exhibition; the second stage will be possible to identify the Social Vulnerability Index of local, considering the susceptibility factors, ability to cope and adaptability. In the third moment, the indices will be overlapped and, therefore, the Local Disaster Risk Index (IRDL) of the areas under analysis will be diagnosed, considering the Equation: R = E x VS, where R is Risk; And it means Exposure and VS refers to Social Vulnerability. The result of this work is intended to identify the risk of local disaster in a timely manner by detailing the dimensions: social vulnerability and exposure.
