Cotopaxi volcano ash eruption dominating the city of Quito

Cotopaxi, the second highest active volcano in the world (5897m) has entered in a pre-eruptive process. Historically its activity started in 1534 when the Spanish conquistadors began to venture into the territories that are now Ecuador. After this episode, Cotopaxi has erupted several times, destroying its environment. The biggest and most devastating eruption occurred in 1877. The lahars produced by melting glaciers went down fast with enough force to devastate cities and valleys and to continue to the Pacific Ocean, situated at 250 km.
