TL;DR: A complex sequence of pyroclastic flows and surges erupted by Nevado del Ruiz volcano on 13 November 1985 interacted with snow and ice on the summit ice cap to trigger catastrophic lahars (volcanic debris flows), which killed more than 23,000 people living at or beyond the base of the volcano.

TL;DR: In this paper, the authors describe monogenetic volcanic fields associated with subduction-related polygenetic volcanism in the northernmost part of the Andes Northern Volcanic Zone (NVZ) (2° S to 4°30′N).

TL;DR: In this paper, the authors discuss the geochemical aspects and the tectonic setting of the effusive activity between 2.0 to 1.0 Ma (the Ancestral Ruiz stage) of Nevado del Ruiz Volcano (NRV: 4° 50-55'N, 75° 14-20' W, 5,390 masl), this volcano rises at the northernmost end of the Andean volcanic chain in the Cordillera Central of Colombia.

TL;DR: The Tumaco basin is a Colombian Caribbean Oceanic Plateau sliver docked with Santonian-Campanian island arcs that was incorporated into the Colombian Pacific forearc during the Paleocene to Eocene as discussed by the authors.

TL;DR: In this article, a contribution integrating new U/Pb zircon ages, heavy mineral analyses and biostratigraphic constraints from the Neogene sedimentary record of the fore-arc and intra-arc basins and volcano-plutonic rocks of southwestern Colombia was made to reconstruct these orogenic processes.
