Global Volcanism Program | Image GVP-04492

A dark lava flow descends the upper western flank of Sangay volcano in 1976.  The lava flow originated from the southernmost of several small craters at Sangay's summit.  This frequently cloud-covered volcano is Ecuador's most active.  Almost continuous minor explosive activity took place from 1728 until about 1916, and resumed in 1934.  Occasional larger eruptions produced detonations heard hundreds of km away.   Photo by Minard Hall, 1976 (Escuela Politécnica Nacional, Quito).
