Cotopaxi (0.7S 78.4W) is a stratovolcano with a summit elevation of 19,388
feet (5,911 m). It has erupted 50 times since 1738. The 1877 eruption melted
snow and ice on the summit, which produced mudflows that traveled 60 miles
(100 km) from the volcano. The most recent eruption of Cotopaxi ended in
1904. Reports of an eruption in 1942 have not been confirmed. The most
recent activity was an increase in steam emissions, melting snow, and small
earthquakes from 1975-1976.
