30 years ago in Colombia, an avalanche of mud, lava and water destroy a town of nearly 32,000 people. In the days leading up to the final tragedy, November 13, 1985, an incessant rain of ash not allowed see the sun. The volcano Nevado del Ruiz was several months warning that would burst. The government of Belisario Betancourt and local authorities ignored the signs of “The sleeping lion". That day, around midnight and without warning, the volcano spit out all his anger as dropped a huge downpour that caused the nearby river burst its banks. A deadly mix of stones, mud and hot lava come down mercilessly by the slope of the mountain to one place: Armero. 25,000 people died in short minutes. Nature was implacable. As much as you try, you can not fight against her, and if you think cannot be so vile, it is. It was so cruel, that all this happened at night, while many were already asleep. I came back with some survivors to where they lived, remembering memories and silences.
