Geological summary

The Agua de Pau stratovolcano in central Sao Miguel Island contains an outer 4 x 7 km caldera formed about 30,000-45,000 years ago and an inner 2.5 x 3 km caldera that was created about 15,000 years ago. The younger caldera is partially filled by the Lagoa do Fogo caldera lake. Several post-caldera lava domes were emplaced on the northern and western flanks, but activity in the caldera did not resume until about 5000 years ago. The 3 km3 Fogo-A plinian pumice fall deposit was emplaced at this time. Numerous flank cinder cones mark radial and concentric fissures, some of which have been active during historical time. The latest trachytic explosive eruption took place during 1563. Prominent hot springs are located on the NW flank.

From Wikipedia

Água de Pau Massif is a stratovolcanic complex, located in the central part of the island of São Miguel, in the Portuguese archipelago of the Azores. More recognizable for the Lagoa do Fogo at its centre, the volcanic complex includes centuries of geomorphological structures that include lava domes, cones and encrusted lava flows that have marked its history from, the last, 45,000 years BC.
