Collapse of the Caldera volcanic activity, before the final act: the catastrophic eruption of the Sesia supervolcano some 282 million years ago. It is estimated that more than 500 km3 of ash and lapilli were erupted in a very short time; at the same time, the entire volcanic apparatus collapsed and huge blocks collapsed into the caldera that had formed, a chasm at least 13 km in diameter. Much of the erupted material fell back into the caldera, mixing with the blocks and forming the chaotic set of rocks
