Since 1738, Cotopaxi has erupted more than 50 times, which created the numerous valleys formed by lahars (mudflows) around the volcano. Cotopaxi poses a high risk to the local population, their settlements and fields. Cotopaxi's most violent eruptions in historical times occurred in the years 1744, 1768, and 1877. In the 1877 eruption pyroclastic flows descended all sides of the mountain, with lahars traveling more than 100 km into the Pacific Ocean and western Amazon basin draining the valley.
