Geotecnologias aplicadas à análise de risco a desastres ambientais de um conjunto habitacional

The lack of urban planning has led to increased land use and occupation of environmentally inadequate areas, leaving the resident population vulnerable to disasterrisk. The risk analysis defines spatial and temporal conditions and indicates the probability of damages, besides that it contributes for the reduction and control of risks through risk management. The objective of this work was to carry out disaster risk analysis at the Monte Cassino Housing Complex, located in the Jaguaribe neighborhood, in João Pessoa city, Paraíba State, based on on-site visits and the use of geotechnologies. The methodology was based on the Guide for Emergency Registry of Landslide Risks, proposed by the Ministry of Cities, Brazil Government, and on the Property Inspection Standard of the Brazilian Institute of the Engineering Assessments and Expertise of São Paulo State. For the preparation of the thematic maps, we used: survey of the topographic data, descriptive data collection of each lot and residence, informal interviews with residents, and processing and spatial analysis of digital data. The main results obtained indicated that 48 out of the 250 lots presented a VERY HIGH degree of risk, requiring the immediate removal of 190 people. Also, 12 housing lots presented a HIGH degree of risk, which need to be constantly monitored. Therefore, the study proved to be very effective for the diagnosis of the environmental impacts governed by municipal spatial planning legislation
