Details for: Ruiz, Nevado del
Nevado del Ruiz is a broad, glacier-covered shield-like volcano that covers >200 sq km. The modern cone consists of a cluster of lava domes constructed within the summit caldera of an older Ruiz. The ash-mantled summit of Nevado del Ruiz volcano is seen here from the ESE on December 18, 1985, a little more than a month after the catastrophic eruption of November 13. The devastating 1985 lahars swept down four major river drainages that day and caused more than 23,000 fatalities. Photo by Norm Banks, 1985 (U.S. Geological Survey).
