Since 2002, when scientists speculated that a new eruptive episode could be imminent in the waters between Sicily and Tunisia, where the Island of Graham (or Ferdinandea) used to be, I.I.M. has been monitoring the area with particular care, carrying out regular surveys to measure any changes in the seafloor.

The Island of Graham (Ferdinandea) has been appearing and disappearing since the First Punic War. Its most recent appearance was in July 1831. At its maximum, it was 4,800 metres in circumference and 63 metres in height and sported two lakes. Because of its strategic location, different nations fought over it, but by December the seamount disappeared, as quickly as it had appeared less than six months earlier.

Data collected by I.I.M. throughout the years shows that the summit depth has remained seven metres under sea level so far, but the volcanoes of the Phlegraean Fields of the Sea of Sicily are still active and surprises can always be expected.
