@article{Naranjo1986EruptionOT, title={Eruption of the Nevado del Ruiz Volcano, Colombia, On 13 November 1985: Tephra Fall and Lahars}, author={J L Naranjo and Haraldur Sigurdsson and Steven Carey and William J. Fritz}, journal={Science}, year={1986}, volume={233}, pages={961 - 963} }
A small Plinian eruption of the Nevado del Ruiz volcano in Colombia ejected 3.5 x 1010 kilograms of mixed dacite and andesite tephra on 13 November 1985, with a maximum column height of 31 kilometers above sea level. Small pyroclastic flows and surges, generated during the initial stage of the eruption, caused surface melting of approximately 10% of the volcano's ice cap, leading to meltwater floods. The erosive floods incorporated soils and loose sediments from the volcano's flanks and…
