Formation of Stanley Patch volcanic cone: New insights into the Evolution of Deception Island Caldera (Antarctica)

Deception Island (South Shetland Islands) is one of the most active volcanoes in Antarctica, with more than 20 explosive eruptive events registered over the past centuries. Recent eruptions (1967, 1969, and 1970) and volcanic unrest episodes (1992, 1999, and 2014-2015) demonstrate that volcanic acti...
