Eruptive history

As with many volcanoes in the region, Bravo's eruptions are often characterized by a central vent (caldera) eruption, followed by an explosive eruption and pyroclastic flows. However, it is unique in the fact that its eruption have also produced lava domes in its caldera. Such eruptions occurred in 1720 ± 150 years, 1050 ± 75 years, and 750 AD ± 150 years (through radiocarbon dating). Eruptions consisting of just a central vent eruption and subsequent explosive eruption took place in 1330 ± 75 years, 1310 BC ± 150 years, 1050 BC ± 200 years and 4280 BC ± 150 years. [1]

Nevado del Ruiz, also known as La Mesa de Herveo is a volcano on the border of the departments of Caldas and Tolima in Colombia, about 129 km (80 mi) west of the capital city Bogotá. It is a stratovolcano composed of many layers of lava alternating with hardened volcanic ash and other pyroclastic rocks. Volcanic activity at Nevado del Ruiz began about two million years ago, during the Early Pleistocene or Late Pliocene, with three major eruptive periods. The current volcanic cone formed during the present eruptive period, which began 150,000 years ago.

Galeras is an Andean stratovolcano in the Colombian department of Nariño, near the departmental capital Pasto. Its summit rises 4,276 metres (14,029 ft) above sea level. It has erupted frequently since the Spanish conquest, with its first historical eruption being recorded on December 7, 1580. A 1993 eruption killed nine people, including six scientists who had descended into the volcano's crater to sample gases and take gravity measurements in an attempt to be able to predict future eruptions. It is currently the most active volcano in Colombia.

Cerro Azul, sometimes referred to as Quizapu, is an active stratovolcano in the Maule Region of central Chile, immediately south of Descabezado Grande. Part of the South Volcanic Zone of the Andes, its summit is 3,788 meters (12,428 ft) above sea level, and is capped by a summit crater that is 500 meters (1,600 ft) wide and opens to the north. Beneath the summit, the volcano features numerous scoria cones and flank vents.

The Nevado del Quindío is an inactive volcano located in the Central Cordillera of the Andes in central Colombia. The summit marks the tripoint of the departments of Risaralda, Quindío and Tolima, and is also the highest point of the departments of Risaralda and Quindío. The mountain is one of the highest peaks in the Los Nevados National Natural Park, which is a wildlife sanctuary. There are no historical records of any eruption. The andesitic volcano is located on top of the Palestina Fault.

Cerro Negro de Mayasquer is a volcano on the border of Colombia and Ecuador. It lies 3 kilometres (2 mi) north-west of the volcano Chiles, and the two peaks are considered part of the same Chiles-Cerro Negro volcanic complex. These volcanoes, together with Cumbal are andesitic in rock type. A 1936 eruption reported by the Colombian government agency INGEOMINAS may have been from the Ecuadorean volcano Reventador, otherwise the volcano has not erupted for around 160,000 years.

The Nevado El Cisne is a volcano in the Central Ranges of the Andes in Colombia. Its summit is at an altitude of 4,636 metres (15,210 ft). The mountain is one of the five lava domes of the Nevado del Ruiz volcano complex. Despite the nevado part of the name, indicating a permanently snow-capped mountain, the summit of El Cisne is now below the permanent snow line as a result of global warming, and it is no longer considered a true nevado. The volcano is located over the Palestina Fault, that crosscuts the underlying El Bosque Batholith of Eocene age, dated at 49.1 ± 1.7 Ma.
