The approach to disasters in Social Sciences has entailed the challenge of its dominant interpretation, considering its strong appropriation by the so-called hard sciences. Such effort has enabled to unveil the existence of a dispute for its appropriation and the presence of discursive and practical strategies marking the positioning of different social actors involved and highlighting both diversity and complexity. This article intends to propose reflections on a certain form of resistance and protest, arising from social suffering that has marked the experience of specific groups threatened to suffer deterritorialization, focusing mainly those affected by a tailing dam breach in Mariana/MG. Since the disaster in November 2015, communities located immediately downstream the dam suffered deep changes in their territorialization, likewise thousands of farmers, traders and fishermen had their productive activities affected along Doce River – losses that impact the material and symbolic support of their experiences in the territory. The analysis aims to investigate those aspects deemed relevant in the resistance of afflicted communities, explicit in valuable struggle strategies triggered in order to cope with the underway disaster. A Sirene Newspaper – to not forget represents one of those resources and has been shown to be essential to maintain and reassert the memory and organization of these collective subjects.
