The mud volcanoes at Santa Barbara and Aragona (Sicily, Italy): a contribution to risk assessment

<p>The Santa Barbara and Aragona areas are affected by mud volcanism (MV) phenomena, consisting of continuous or intermittent emission of mud, water, and gases. This activity could be interrupted by paroxysmal events, with an eruptive column composed mainly of clay material, water, and gases....
