A dam holding liquid waste collapsed on June the 4th in Cieneguita, Mexico, leaving 3 dead and between 8 and 23 missing.

The current was so strong that people, machinery and vegetation was carried away by the river, that was coloured white from the chemical products, sand and earth that formed a dense mass.

The satellite images from Sentinel-2 show before and after the event, clearly depicting the white river of tailings. So far, the environmental impact is unknown.
