Description:
On the Island of Vulcano (Aeolian Archipelago, Italy) the temperatures of fumarole
emissions, have ranged from about 700 ◦C to the boiling point. Since the end of the last eruption
(1890 A.D.), many periods of increased heating of hydrothermal systems, underlying the La Fossa
area have been identified, but an eruptive condition has not yet been reached. The time variation
of the high temperature fumaroles has been tracked by the network of sensors located at a few
discrete sites on the summit area of La Fossa cone. The same continuous monitoring network has
been working for more than 30 years. The time series shows that a natural cyclic modulation has
repeated after almost 20 years, and its periodicity yet has to be discussed and interpreted. The
statistical approach and the spectral analysis could provide an objective evaluation to reveal the
timing, intensity, and general significance of the thermodynamic perturbations that occurred in the
hydrothermal circuits of La Fossa caldera, during the study period. The continuous monitoring
data series avoid unrealistic interpolations and allow promptly recognizing changes, which perturb
the hydrothermal circuits, highlighting—possibly in near real time—the transient phases of energy
release from the different sources (hydrologic/magmatic).
