The 5-km-wide Sete Cidades caldera, seen from the southern rim, with lakes Lagoa Verde (foreground) and Lagoa Azul (background) that occupy much of the central caldera floor. To the east (right) and west (left) of these lakes are several pyroclastic cones that have formed in explosive eruptions during the last 5,000 years.
