Volcanic activity is an issue that residents must deal with living in many parts of Tolima, due to its location over various geological faults. In 1985, for example, the Nevado de Ruiz erupted and caused the Armero tragedy, which caused the death of more than 23,000 people and destroyed the town of Armero. The department's capital, Ibagué, is also built near a very large active volcano; the Nevado del Tolima. It stands at 5215 meters (17,110 ft) high, and last erupted in 1943. The Combeima River flows from this mountain and passes by Ibagué, part of which is situated close enough to the river to be put in danger by volcanic flows, should the volcano ever erupt again.
