Details for: Fogo
The massive 9-km-wide, horseshoe-shaped Cha caldera truncates the summit of Fogo stratovolcano, the most prominent in the Cape Verde islands. An ash plume (center) rises from the western flank of a steep-sided central cone, Pico, that rises more than 1 km above the caldera floor to form the 2829 m high point of the island. Pico, which is capped by a 500-m-wide, 150-m-deep summit crater, was apparently in almost continuous activity from the time of Portuguese settlement in 1500 CE until about 1760.

Location: Pico do Fogo (View Details at MaGa DB)
Description: Fogo (476 km2) is the fourth largest island in the archipelago of Cape Verde with a roughly circular shape. Most of early historical eruptions (during the seventh and eighteen centuries) have occurred at the summit area of Pico do Fogo, whereas recent eruptions in Chã das Caldeiras have occurred mainly along WSW-ENE- oriented fissures. Pico do Fogo volcano is characterized by the existence of a fumarolic field situated NW inside the summit crater (Figure 2d) and composed by low- and high-temperature gas discharges (90°C to 100°C and above 200°C, respectively) with widespread sulfur precipitates at the surface, typical of hydrothermal alteration
