Resumo

This article aims to analyze the collapse event occurred in the urban landscape of the city of Abaetetuba. The study was conducted using the Peloggia classification (1996) on technogenic plain emphasizing the risks in this landscape and consultation to the CPRM Report (BRASIL, 2014), which enabled the understanding of the causes of the disaster. Also the surveys were conducted through fieldwork, interviews with the people of the neighborhood, photographic records and map preparation. We noticed that the urban landscape of Abaetetuba presents risks due to the grounding of its plain with several unsuitable materials (solid waste, debris, building debris, seeds, sawdust, etc.). When it comes in contact with the humidity, that type of landfill becomes fragile, representing a threat. Thus, we can conclude that the disaster in the São João Batista neighborhood occurred due to several factors, such as: the inappropriate material used to ground the site; the weight of the constructions plus the loads resulting from the use; the flow of heavy vehicles; the existence of a depression in the original soil near the point of collapse and absence of a study corresponding to the soil characteristics to ensure the decision on the appropriate foundation for this type of soil.
