SEW – Save the Etna World
At more than 3,330 m high and ~40 km wide, Mount Etna in Sicily, Italy, is the highestvolcano in Europe and one of the most active in the world. Etna stands majesticwherever you look at it, showing a distinctive skyline from each side. More than 200,000people live around its mid-slopes, while another 300,000 are in the biggest city, Catania,located at its southern lower slope. The volcano is so imposing that there are manydifferent landscapes and habitats, often highly dissimilar. Ente Parco dell’Etna (EtnaPark) is the institution, started in 1987, covering the core of the volcano, protecting itsbiodiversity, ecosystems and landscapes, and lastly promoting the sustainabledevelopment of loca…
Patterns in the recent 2007-2008 activity of Mount Etna volcano investigated by integrated geophysical and geochemical observations
[1] Seismic, deformation, and volcanic gas observations offer independent and complementary information on the activity state and dynamics of quiescent and eruptive volcanoes and thus all contribute to volcanic risk assessment. In spite of their wide use, there have been only a few efforts to systematically integrate and compare the results of these different monitoring techniques. Here we combine seismic (volcanic tremor and long-period seismicity), deformation (GPS), and geochemical (volcanic gas plume CO2/SO2 ratios) measurements in an attempt to interpret trends in the recent (2007–2008) activity of Etna volcano. We show that each eruptive episode occurring at the Southeast Crater (SEC)…
