Ferdinandea, Volcanic island remnant in Mediterranean Sea, Italy
Ferdinandea is an undersea volcanic peak beneath the Mediterranean Sea, located roughly 40 kilometers from Sicily's coast. The entire volcanic structure spans several kilometers in diameter and forms a distinct underwater mountain.
In 1831, volcanic activity created a temporary island that triggered intense territorial claims from Britain and the Kingdom of Two Sicilies. The landmass sank back beneath the sea surface within a few months.
Different nations competed to name and claim this emerging landmass when it briefly rose above water. These territorial disputes reveal how much countries valued new land during that era.
The site is not accessible for visits since it lies underwater and can only be observed from boats. Marine specialists conduct regular monitoring to track the volcanic structure.
When the peak rises close to the water surface during active periods, ships can detect its location as a navigation hazard. This undersea feature makes the region an area of interest for maritime traffic.
