Brava

Stratovolkan · Cabo Verde · 956 m

The roughly 9-km-wide Brava Island has numerous domes, coulées, craters, and cones across the island surface, shown in this February 2019 Planet Labs satellite image monthly mosaic (N is at the top). From the SE side towards the center are several domes, including Morro da Pedras and Morro Largo. In the center is the Fundo Grande, Cova Lima Doce, and Cova Joana craters as well as the Munhoto fault zone. Many of the more recent craters formed during phreatomagmatic eruptions.

Ringkasan geologi

Brava Island, 18 km W of Fogo, is the westernmost of the southern Cape Verde islands. The 10-km-wide island contains 15 morphologically youthful craters located along two or three lineaments intersecting along the crest of the island. Most of the younger eruptions originated from the interaction of phonolitic magmas with a large groundwater reservoir contained within an older volcanic series characterized by thick welded ignimbrites and block-and-ash flow deposits. Carbonatitic lavas are also found.
