Cerro Bravo Volcano, Colombia

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 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.
