Ferdinandea: Origin and evolution of volcanic islands
Keywords:
volcanic islands, seamounts, Ferdinandea island, hotspotAbstract
Volcanic islands are structures characterized by different origins depending on the geodynamic context. Some volcanic islands are formed by solidified lava emerged from volcanoes that originally were below the sea level. However, there is other class formed from previously submerged volcanoes that were part of a mid-oceanic ridge. Another type of volcanic island is the one formed by flowing a tectonic plate beneath another. Subduction creates a chain of volcanoes that, as they emerge, form a chain of islands. The last type is formed by a hotspot on which a tectonic plate moves. In this paper examples of the types of volcanic islands and their evolution are addressed, and the case of Ferdinandea Island is specifically analyzed. It is an island located in the south of Mediterranean Sea (Sicily, Italy), whose formation in the 19th century sparked a diplomatic conflict that lasted a few months before its disappearance.
