Twenty-seven years ago, on November 13, 1985, the volcano erupted twice. Its snow peak melted, and its water, ashes and lava created an avalanche with winds forceful enough to elevate cars and sweep people away. The hot mud crashed down buildings.
The volcano left 25,000 people dead and 18,000 homeless in the town of Armero as well as neighboring Ibagué, Lérida, Mariquita, Alvarado and Venadillo in Tolima department.
