BHP Billiton & Vale: Brazil dam burst

On 5 November 2015 a dam in Brazilian state of Minas Gerais burst its banks resulting in 6 deaths and 631 injured. 21 people are still missing1. The cause of the overflow of water, mud and mineral waste from the mine is still being investigated. The mine is jointly by BHP Billiton and Vale SA, and operated by the mining company Samarco.2. The water and mud have reached and devastated a village (Bento Rodrigues) 7 km away.3 There is a risk that there will be further landslides to come4. The majority of the inhabitants of the village have been housed in temporary shelters and examined for potential health problems. There are reports of toxic chemicals in the mud, which Samarco denies. An investigation into the causes of the spill has been initiated by the prosecution. Although the causes are still unknown, stricter regulations for mining companies in Brazil is now being discussed5.

Here’s a video showing the extent of the dam break.
