Cerro Bravo is a relatively low dominantly dacitic lava-dome complex north of Nevado del Ruiz volcano that was constructed within the Pleistocene Quebrada Seca caldera. A series of moderate plinian eruptions during the Holocene has been accompanied by pyroclastic flows and lava dome growth. Although historical records of the roughly 4000-m-high Cerro Bravo eruptions have not been found, stratigraphic evidence indicates that the volcano last erupted sometime between the 1595 and 1845 eruptions of Ruiz volcano.

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Cerro Bravo is seen from Delgaditas on its east side. The summit dome with a prominent spine was extruded during the most recent eruption. An older lava dome and cone complex is situated to its left. Multiple collapse events sent block-and-ash flows down over viscous lava flows (center) and onto the Plan de Arriba (lower left). The low, tree-covered slope 1/4 of the way from the left side of the photo is the remnant of the pre-Cerro Bravo volcano that was destroyed by a Pleistocene caldera-forming event.

Cerro Bravo volcano, Colombia, is seen to the north from the northern flank of Nevado del Ruiz. The CB1 summit dome rises above an older dome and cone complex, probably produced during the CB7-CB5 phase of activity. Below this, the remains of the pre-Cerro Bravo volcano are truncated by the Pleistocene Quebrada Seca Caldera. Most of the Pleistocene lava flows in the foreground are associated with Nevado del Ruiz.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
