The original seat of the region was destroyed on 13 November 1985, after an eruption of the Nevado del Ruiz Volcano produced lahars that buried the town and killed about 23,000 people. Approximately 31,000 people lived in the area at the time. The incident became known as the Armero tragedy. While the destruction of the town made world news in its own right, the best known victim was Omayra Sánchez, a young girl who died after being trapped by water and concrete up to her neck for three days. After this event, the town of Guayabal was assigned as the seat of the municipality of Armero, rendering Armero a ghost town.
