More About Sangay
Location: 78.3W, 2.0S
Elevation: 17,154 feet (5,230 m)
Sangay has been erupting virtually continuously since at least 1934. Eruptions
are Strombolian in character. Mild explosions
frequently emit ash. In August of 1976, an expedition was caught near the summit
during an explosion that dropped blocks up to 14 inches (35 cm) in diameter
on the group. Two people later died from their injuries. The first documented
eruption of Sangay was in 1628. Photograph by G.E. Lewis, 1946. Courtesy

Sangay is the southern most stratovolcano in the northern volcanic zone of the Andes. Volcanism in the northern volcanic
zone is the result of subduction of the Nazca Plate beneath the South American Plate. South of Sangay the angle of
subduction is too shallow to generate magma. These relationships highlight the critical role of the asthenosphere in
producing magma for the volcanic arc volcanoes.
