Temperatures of Fumaroles measured by contact sensor (Thermocouple Type K) on the upper rim of La Fossa cone (Island of Vulcano, Italy)

These data are a part of the INGV’s long-term surveillance efforts on the Island of Vulcano (Aeolian Archipelago, Italy), begun in 1984. The dataset consists in the temperatures of fumaroles (HTF), recorded by a remotely controlled monitoring network, located in the summit area of La Fossa cone. HTF temperatures have played a pivotal role in detecting the past and present volcanic unrest, underlining the network’s sensitivity and
effectiveness. Long-term monitoring displayed its ability in identifying transient processes, on the base of multi-disciplinary comparisons. The monitoring sites are four fumarole vents. The measure by contact sensing in the fumarole vent occurs at depth of -0.5m. The sampling interval is 1 hour, this monitoring activity is still going on, and we can program different logging intervals, on demand.
