On June 4, 2011, the complex volcano Cordón Caulle started an eruption process that still lasts. During the first days, hundreds of families were evacuated and hosted in in schools to prevent any fatalities. The eruption turned air traffic in South America into chaos. While the activity has waned, the ash rain over Rupumeica, Puyehue and Riñinahue has caused many health problems to the people, animals and farming of these regions. The authorities have not communicated if the ashes are toxic or not, so the inhabitant keep living surrounded by them.
