[4] The cause of the subsidence is attributed to the impact of four decades of mining the soil to extract rock salt, an ore used to manufacture items such as caustic soda and PVC, by Braskem.

On 30 November 2023, the city of Maceió decreed a state of emergency in the municipality for 180 days due to the "imminent collapse" of a mine belonging to Braskem in the area of Mundaú Lagoon, in the Mutange neighborhood.

In addition to dissatisfaction with the agreements proposed by Braskem, residents are still living with accelerated growth in the population of stray cats and mosquitoes; some refuse to leave the risk areas, which have been periodically updated on official City Hall maps since 2019.

[19] The Maceio City Hall created the Integrated Management Office for the Adoption of Measures to Address the Impacts of the Sinking of Neighborhoods (GGI Bairros), through Decree No.

[22] Braskem does not officially admit to having caused the disaster, but signed an agreement in the Alagoas courts that provides for the payment of more than 12 billion reais to compensate residents and shopkeepers, as well as the relocation of public facilities such as schools and health units.

[5] A group of Maceió residents, represented by three law firms, have filed a lawsuit against Braskem in Rotterdam, the Netherlands, claiming that the compensation offered by the company does not cover all the damages.

[25] On 1 November 2024, 20 people affiliated with Braskem were indicted by the Federal Police of Brazil on charges of damage to public property and environmental crimes relating to the sinking.
