Brazil dam threat:

Mining company Vale has evacuated almost 200 people after inspectors reported signs that a dam holding mining waste could collapse in the region of Macacos, about 16 miles south of Belo Horizonte, the capital of Minas Gerais state. Saturday night’s evacuation came three weeks after the collapse of another mining dam run by Vale that caused the deaths of at least 166 people and left at least 147 missing. Vale said in a statement that the new evacuation was ordered for safety reasons. The company said it is unclear when the evacuees would be allowed to return home.
