Description:
The hydrothermal activity represents an evidence of high-energy submarine processes related to active or recent
volcanism. Shallow hydrothermal vents represent a unique study opportunity due to the easy access to the vented
fluids. The hydrothermal fluids released off the coast of Panarea Island (Aeolian arc, Italy) have been intensively
investigated since mid 80’s. The sudden unrest of submarine volcanic activity occurred on November 2002 with a
submarine low-energy explosion, dramatically changed the geochemical features and the degassing rate of the
submarine hydrothermal vents and pushed the scientists to develop new methods to monitor the venting activity. A
better inside of the whole submarine hydrothermal system has been achieved by the development of new
investigations methods and geochemical models. The new information closely linking the geothermal and the
volcanic activity of the Island require that a continuous monitoring of the submarine hydrothermal activity is carried
out.
A new sea-floor observatory has been developed for multidisciplinary monitoring activity and to perform real-time
data transmission from the sea bottom. Among the other sensors, an acoustic probe, installed for a long-term
recording of the sound of the bubbling gases in a frequency range of 0.5-3 kHz, gave useful information of a tight
link between the submarine volcanic activity of Panarea Island and the crater explosions of the nearby active volcanic
island of Stromboli
