Scientific paper

In the summer of 1982, the Phlegraean Fields, a nested resurgent caldera located in the densely populated Naples area of Italy, started to give signals of unrest. However, after about 30 months of soil uplift (up to 5 mm per day) and intense shallow-depth, swarm-type seismicity (up to 100 shocks/hr∥, these phenomena diminished and alert warning for an imminent volcanic eruption ceased. A similar scenario went on at Vulcano, Italy, where an increase in the amount of fumarolic output and in gas temperatures (more than 700°) began in the winter of 1992. Also in this case, no eruption occurred, and gas temperatures and emission rates slowly returned to their normal values. Why did the Phlegraean Fields and Vulcano not erupt when they appeared to be in a pre-eruptive stage? The difficulty in answering this question is due to our inadequate knowledge of the internal structure of these volcanoes. We simply do not know how these volcanoes work and how much we can rely on the various ``precursors'' of the eruptive activity. For this reason, one of the main objectives of volcanology is to understand where the magma storage reservoirs are located and the residence time of magmas in these reservoirs.
