SfondoRoccamonfina is a large Pleistocene stratovolcano with numerous post-caldera cones within the summit caldera and on the flanks. The eruptive history consists of three main phases. The first stage built the main cone via lava flows and pyroclastics. The second stage is defined by large explosive eruptions, tuff deposits, and caldera collapse. The third stage formed the lava flows, domes, and scoria cones that exist on the volcanic edifice today. A report of a historical eruption in 269 BCE ("a flame shot up and burned for three days near Cales" (Stothers and Rampino, 1983)) is considered uncertain by Scandone and Principe (1986), who noted that the youngest products have been dated at 0.30 million years. Later work (Rouchon et al., 2008) dated summit caldera lava domes at 170-150,000 years ago. Peccerillo (2005) gives an age range of 0.58-0.1 Ma for Roccamonfina activity.
