지질학적 요약
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.
Wikipedia 요약
영어 요약Brava is an island in Cape Verde, and is part of the Sotavento group, in the central Atlantic Ocean. At 62.5 km2 (24.1 sq mi), it is the smallest inhabited island of the Cape Verde archipelago, but at the same time the greenest. First settled in the early 16th century, its population grew after Mount Fogo on neighbouring Fogo erupted in 1680. For more than a century, its main industry was whaling, but the island economy is now primarily agricultural.
