Etna Volcano (Sicily, Italy) is one of the Permanent Supersites of the GEO Geohazard Supersites and Natural Laboratory (GSNL) initiative. GSNL is a voluntary international partnership which promotes the Open Science paradigm and aims to improve the Earth Science research and geohazard assessment in support of Disaster Risk Reduction (https://geo-gsnl.org/).

There is a variety of in situ data and products available for Etna Supersite spanning from the geophysical to geochemical kind, among which seismic and GPS data, wrapped differential interferograms, geochemical bulk rock data, geological maps, and VONA reports.

There are also diverse space data made available by different providers, such as COSMOskymed, MODIS, AVHRR, Sentinel, Pleiades, TerraSAR-X, which allow synoptic observations of the volcanic area.

The opportunity of integrating in situ and satellite data fosters new science and better assessment of the volcanic hazards. The amount of information available, combined with the almost persistent eruptive activity, makes Etna Supersite one of the most dynamic natural laboratory worldwide.
