Mount Pico volcano is part of the Madalena Volcanic Complex, one of three volcanological units that comprise the island of Pico, associated with three historic eruptions in 1562, 1718 and 1720. Current morphology suggests an age dating to the Holocene age, confirmed by radiocarbon dates younger than 6000 years. Structurally, this complex can be subdivided into two other sections: the Pico Volcano and the East Fissural Zone.
