Agua de Pau

Agua de Pau, a stratovolcano with a caldera, erupted in 1563 and 1564. The 1563 eruption was at the Cerro Qurimado vent on the northwest flank of the caldera. The eruption lasted almost a month and was initailly Plinian and later produced lava flows that caused some damage. The 1564 eruption lasted only two days and was near Lagoa do Fogo caldera. It may have been a phreatic eruption. Thick pumice deposits on the flank of the volcano are probably the result of caldera-forming eruptions.
