The SE floor of Sete Cidades caldera contains a large trachytic lava dome with two craters containing Lagoa de Santiago and Lagoa Rasa. The rim of Lagoa de Santiago crater is visible in the center. The visible lakes in this image are the Lagoa Verde (left foreground) and Lagoa Azul (left background), that occupy much of the caldera floor. Both explosive eruptions forming Santiago and Rasa occurred within the last 5,000 years. Photo by Rick Wunderman, 1997 (Smithsonian Institution).
