Faial Caldera, Faial Island, Portugal
View Original Description
The nature of the stratovolcano structure results in an island that converges at the central Caldera Volcanic Complex, although the highest point occurs along the southern rim, at the peak of Cabeço Gordo (1,043 m above sea level). The Caldeira (Caldera) is almost circular, 2000 m perimeter, with a 400 m depth below the summit of Cabeço Gordo (almost 570 m above sea level). Its center is broken by water marshes, thickets, and minor cinder cones, and surrounded by almost vertical cliffs with a diverse vegetation, both endemic or invasive to Macaronesia. It is constituted by pyroclastic material, pumitic projectiles, phreatic and phreatomagmatic deposits and examples of pyroclastic flows and lahars. It's part of the UNESCO Azores Geopark.
