Machin

Volcano
Cerro Machín volcano is a small stratovolcano about 20 km WNW of the city of Ibagué, Colombia. Although there are no historic eruptions, Machin is considered one of the most dangerous volcanoes in Colombia, because it has produced devastating explosive eruptions in its past and will likely to continue so. Pyroclastic flow deposits have been found up to 40 km and mud flow deposits (lahars) up to 109 km distance from the volcano along the Coello and Magdalena rivers. The last known activity took place about 800 years ago.
