Ischia is a rare case of a well-exposed caldera system that has experienced rapid recent resurgence, which can be used to dissect the anatomy of an otherwise inaccessible active hydrothermal system developed in a caldera-forming environment. Integrated analyses of melt and fluid inclusions, mineralogy and stable isotopic compositions of pumices, tuffs and syenitic xenoliths of the Ischia volcanic system provide strong physico-chemical constraints on the shallow magmatic reservoir and the hydrothermal system.

The Campi Flegrei caldera is one of the highest risk volcanic areas on the Earth. Our research documents a 150 year-long period of intense volcanism following less than 200 years of repose after the Agnano-Monte Spina Plinian eruption (4.1 ka). The new data show that the renewal of volcanism was preceded by an uplift of a few tens of meters, triggered by mafic refilling of reservoirs at depths of 3 km or less.Our studies also indicate for the first time the occurrence of contemporaneous eruptions from at locations in different sectors of the caldera.
