FTB.1 | Active volcanoes in southern Italy (Etna, Stromboli, Vulcano and Lipari) and their multi-hazard
This fieldtrip will focus on the geological, geochemical and petrologic aspects of active volcanoes of Southern Italy, along with the processes of evaluation, mitigation and management of their volcanic hazard and risk. This is one of the most active tectonic and volcanic setting in the Mediterranean area, comprising a number of active (Stromboli, Vulcano) or dormant (Lipari) volcanic islands in the Aeolian Arc, together with the Mount Etna. They have attracted the attention of a great number of volcanologists, and can be rightfully considered the cradle of the scientific discipline of Volcanology, giving the name to the world-wide definitions of the ‘strombolian’ and ‘vulcanian’ styles of eruptive activity. We will appreciate the incessant and rhythmic explosive activity of the summit craters of Stromboli and the Sciara del Fuoco collapse scar, together with the INGV real-time monitoring network, which makes this volcano among the most observed and studied in the world. The observation of the eruptive deposits of historical eruptions of Vulcano will be joined to the analysis of the main features of its present-day intense fumarolic activity. Moreover, we will observe the well-known Rocche Rosse obsidianaceous lava flow and Mt. Pilato pumices, representing the latest activities of Lipari Island during the Middle Ages. Then, a geological walk toward the summit area of Mount Etna, through the volcanic products of 2001, 2002-03, 2008-10 and the 2011-2016 paroxysms, will give the possibility to observe the variability of eruptive scenarios of this majestic volcano.
The spectacular geological outcrops along these volcanic systems will give the bases to discuss about the main aspects of volcanic hazard, risk mitigation and crisis management of their possible future eruptions in a highly-urbanized territory characterized by intense tourism exploitation during the summer, through talks with the population and a simulation of the response of Italian Civil Protection and Institutions to an eruptive crisis carried out with the collaboration of the Specialized CERtificate in assessment and management of Geological and Climate related Risk (CERG-C) of the University of Geneva, Switzerland.
