The volcano Cotopaxi had two explosions on Friday, showering ash on the southern Quito, Ecuador. Cotopaxi sent ash 3 miles into the atmosphere. Officials stated that there is no impending probability of a major eruption. Cotopaxi is a stratavolcano and is formed by the Pacific plate subducting under the South American plate. The last time Cotopaxi erupted was in 1940.
