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.
