The Picos Volcanic Fissural System (Portuguese: Sistema Vulcânico Fissural dos Picos) is a system of scoria cones that build up the central region of the island of São Miguel (between Sete Cidades and Água de Pau volcanoes). This volcano is very young with most of it only 5000 years old. The only recorded eruption was in 1652, but seven other eruptions have taken place in the cinder cone group in the last 10,000 years.
