    It is commons practice to dump mine tailings in an area near a mine. In areas where it rains, water may accumulate behind burms and the tailings which form an earthen dam.

    In valleys, lakes can form behind dams leading to potential failures.

    The water and mud was reported to be 15 to 20 in depth, or height.

    About 80% of the village Bento Rodrigues (which is about 93 miles (150 km) southeast of Belo Horizonte, Brazil's third largest city and the capital of the mining state of Minas Gerais) was destroyed. And authorities have trouble reaching the area.

    Google Earth gives a good view of what was sitting above them before the collapse.

    And this is just the very bottom of a much larger mining area.
