Intermittent vapor-and-gas column observed for 3 hours

An intermittent gray column composed of water vapor and solfataric gases was observed for 3 hours on the evening of 14 November 1993. A similar, but less intense column was witnessed on 16 November by observers at the Servicio Agrícola Ganadero (Farm Service Office) and the local police station in Maricunga, 30 km from the volcano.

Dacitic pumice from Holocene eruptions of Nevados Ojos del Salado volcano lines the shores of Laguna Verde, NNE of the volcano. The lake lies near the Chile-Argentina border, between Mulas Muertas and Falso Azufre volcanoes.

The dacitic volcanic complex of El Muerto abuts Nevados Ojos del Salado volcano on the east and NE. The summit of this massive complex contains dacitic lava domes and is cut by a 2.5-km-long depression containing a dozen eruptive centers; an additional two dozen centers lie outside the depression. Lava flows from these centers cover an area of 120 sq km. The summit lava domes are of Pleistocene age, but the complex is cut by ENE-trending fractures that formed during Holocene eruptions of Ojos del Salado.

The NW side of Nevados Ojos del Salado volcano rises above Pliocene ignimbrites and pyroclastic deposits of the Barranca Blanca. These deposits are overlain by dacitic pyroclastic-flow deposits from Ojos del Salado. A break in slope about half way up the volcano is the rim of a somma, inside which the modern edifice was constructed. Dacitic lava flows from the summit cone periodically overtopped the somma rim.

The world's highest Holocene volcano, Nevados Ojos del Salado, rises to 6887 m along the border between Chile and Argentina. The summit complex, which is elongated in a NE-SW direction, is seen here from the NW. The massive volcanic complex contains numerous craters, cones, and andesitic and dacitic lava domes. No historical eruptions have been recorded, but the volcano is fumarolically active.
