252 GNGTS 2016 S essione 1.3 Fig. 1 – Maps of the studied areas with the location of the sites cited in the text: a) Mount Etna volcano; TBL - Monitoring site in the steam heated soil on the northern flank, FBT - low temperature fumaroles. In the left corner the Southern Mediterranean region and the position of mount Etna(white square); b) Sketch map of Vulcano island showing the location of the seismic stations and tiltmeter. In the inset at the upper right corner the location of the monitoring sites of CO 2 , fumarole temperature and soil temperature is reported (from Milluzzo et al ., 2010). Fig. 2 – a) Locations of the monitoring stations of Vulcano island and recorded change of temperature both in high temperature fumaroles fumaroles (b) in the ground profile (c). The red curve in Figs. 2a and 2b show the variable rate of volcano-seismic release during the monitoring period. d) CO 2 content in the fumarole samples.
