Caldeira do Alferes (center) is one of a group of pyroclastic cones constructed on the floor of Sete Cidades caldera. The adjacent cone of Seara is just visible in the background, right of Caldeira do Alferes in this view from the western caldera rim. The forested slope seen in the right foreground is Caldeira Seca. Explosive trachytic eruptions occurred at least 17 times in the past 5,000 years within the caldera.  Photo by Rick Wunderman, 1997 (Smithsonian Institution).
