According to news articles, Enzo Boschi, the head of INGV, stated that seismicity increased near Campi Flegrei Mar Sicilia a group of submarine volcanoes ~30 km S of Sicily, near Tunisia. Boschi stated, "The island could come back to the surface, but we'll have to wait and see... It could be a few weeks or months." The Stromboli On-Line website noted that similar statements have been made several times in the past couple of years. The increased seismicity does not necessarily signify that an eruption is imminent and the island will re-emerge above wave base.
Geologic Background. Campi Flegrei del Mar di Sicilia (Phlegraean Fields of the Sicily Sea) is composed of a group of submarine volcanoes SW of Sicily. The volcanoes were constructed within a submarine depression about 1 km deep in the Strait of Sicily between the SW coast of Sicily and the NE tip of Tunisia, forming submarine banks that are capped by cones that rise to near sea level. Submarine eruptions were reported at the Giulia-Ferdinandeo and Pinne banks during the first Punic war (264-241 BCE), and from the 17th to 20th centuries, sometimes producing ephemeral islands. The 1831 eruption at Ferdinandea (also known as Graham in English or Giulia/Julia in French) produced an ephemeral island that was promptly claimed by the navies of France, Britain, Spain, and Italy.
