When a dam burst at a Samarco mine in the mineral-rich state of Minas Gerais the mud and floodwater that came rushing through the village of Mariana killed at least eight people.
Over a week later more then 20 people are still listed as missing and hundreds remain displaced, their homes destroyed in the tide of mud. Recovery crews are slogging through nearly 100 km of mud-caked floodplain in a search for more victims.
The first Eliene Almeida, head teacher at the municipal school in Bento Rodrigues, knew of the deadly mud flow that destroyed her village was a cry from her husband.
Most villagers were running for higher ground, but no one inside the packed school was aware that a 20 meter high wall of mud and water was approaching.
