Cerro Bravo

Bravo, Cerro

Stratovolcano · Colombia · 3985m

Cerro Bravo is seen from the east. The summit dome was extruded during the most recent eruption and has a spine (a steep dome) near the top. An older lava dome and cone complex is situated to the left. Multiple collapse events sent block-and-ash flows down over lava flows (center) and onto the Plan de Arriba (lower left). The low tree-covered slope (left foreground) is the remnant of the pre-Cerro Bravo edifice that was destroyed by a Pleistocene caldera-forming event.

Geological summary

Cerro Bravo is a relatively low dominantly dacitic lava-dome complex north of Nevado del Ruiz that was constructed within the Pleistocene Quebrada Seca caldera. A series of moderate plinian eruptions during the Holocene were 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 it last erupted sometime between the 1595 and 1845 eruptions of Ruiz.

From Wikipedia
