“Serra Devassa” is a volcanic ridge with a NW-SE trend that develops from the SE border of “Sete Cidades” caldera, as a set of active faults and volcano-tectonic lineaments of monogenetic volcanoes. About 15 small lakes are located in this area, mostly in explosion craters of basaltic scoria cones.
