The Campi Flegrei calderas have produced two of the largest eruptions Europe has seen in the past 40,000 years. Not according to Bob Christiansen. Their study also reveals that the caldera was formed by hotspot-related magmatism interacting with a spreading ridgethe upward magma movement at the ocean floor where the new crust was forming, leading to the joining and eventual separating of Benham Rise with surrounding geologic structures.

Features like a breached rim, intra-caldera benches, and a resurgent dome indicate a multi-phase volcanic history consisting of both quiet and explosive eruptions. Post-caldera volcanism has included the emplacement of multiple ring-fracture lava domes and uplift of the caldera floor, forming the Redondo Peak resurgent dome. With a diameter of 150 kilometers, it may be the worlds largest known caldera (93 miles).
