A gigantic mudslide can be seen sweeping through the Corrego de Feijao open-cast iron ore mine.
It was the second dam disaster in three years at a mine owned by Brazilian mining giant Vale.
The toll from the dam collapse last week at a mine in southeast Brazil has risen to 121 dead and 226 missing, according to officials.
The emergency service for the state of Minas Gerais, where the January 25 disaster occurred near the town of Brumadinho, said the search was ongoing for bodies. All those listed as missing are presumed dead, with no survivors being found over the past week.
It is assumed that all the dead and missing people were workers at the iron ore mine, buried under an avalanche of sludgy mining waste when the dam collapsed above the facility's cafeteria and main administrative area.
Authorities have frozen over USD 3 billion in company assets in anticipation it will pay damages, compensation and fines.
The chilling video that is circulating on social media shows how the dam ruptured and within seconds the mudslide engulfed the mine.
