Today in Latin American history, a volcano erupted causing a mudslide that buries Armero, Colombia killing 23,000 in 1985.

After 69 years of dormancy, the Nevado del Ruiz stratovolcano’s eruption caught nearby towns unaware, even though the government had received warnings from multiple volcanological organizations to evacuate the area when volcanic activity had been detected in September 1985.

As pyroclastic flows erupted from the volcano’s crater, they melted the mountain’s glaciers, sending four enormous lahars (volcanically induced mudslides, landslides, and debris flows) down its slopes at 40 miles per hour.
