A scientific campaign to analyze the tectonic and subvolcanic crustal structures, upon which the Etnais based, will be conducted in June and July. It will be an official presentation in Catania today.

Sixty researchers from various institutions will be involved in this research, conducted within the framework of two European projects , the " Medsuv " - Mediterranean supersite volcanoes - and " Eurofleets 2" projects.

" Tomo -Etna " , a campaign to study under Etna.

The analysis will be done through active seismic techniques, the waves generated by compressed air , and passive , through the natural earthquakes recording .

For marine exploration, various naval units contribute to this activity, the Spanish oceanographic research vessel " Sarmiento de Gamboa ", the hydrographic Greek ship "Aegea " ,and Italian ships.

The acquisition of seismic signals will be through the permanent seismic network of the INGV , supplemented by a temporary network of 100 stations arranged on Etna and the surrounding provinces of Catania , Messina and Syracuse . At sea, a network of stations OBS / H , Ocean Bottom Seismometers , ranging from near Etna to the Aeolian islands .

The study of magnetic and gravity anomalies will be during cruises, through magnetometers and gravimeters .

The data collected will help to establish a precise tomography, and may shed a new light on the process of magma ascent of Etna.
