Three large calderas are seen in this NASA International Space Station image (with north to the upper left) of the Vulsini volcanic complex in central Italy. The 16-km-wide Lake Bolsena (left-center) was formed during major Pleistocene explosive eruptions at about 300,000 years ago and the 8 x 11 km wide Latera caldera (below and to the left of Bolsena) about 160,000 years ago. Post-caldera volcanism produced scoria cones and lava flows (lower left) until recent times. Pleistocene Lake Vico in the Cimini Mountains lies at the right-center.
