But the huge interest the underwater eruption that area. Pantellyariey between Sicily and is grounded in the place where the first lot at a depth of one hundred fathoms did not reach even the bottom. In 1831 there occurred an underwater eruption, which put forward a new island, and he lasted only a few months and was destroyed by sea waves. June 28, 1831 English ship that was found in 37 ° 2 'north latitude and 30 ° 16' east longitude from Ferro, felt a strong jolt, as if ran aground. July 8 here drove Sicilian brigantine, whose captain noticed that the huge mass of water suddenly rose 60 feet above sea level and the club for ten minutes, when the excitement had calmed down over the sea with a terrible noise came a thick cloud of smoke. The phenomenon was repeated every 15 - 20 minutes. July 10, according to another Sicilian captain, got a body of water 60 feet. high and 800 cubits in circumference, it broke away from the column of vapor to 1800 r. in height. July 12 at Shyakki on the shores of Sicily, were ejected volcanic mass and dead fish, and on July 13 over the water column of smoke appeared, brightly lit at night. Aug. 18 above Sicilian ship passed over the same spot and found this little island, rising to 12 p. above sea level, it was in the middle of the crater, releasing friable products and great clouds of vapor. July 20 this island, named the island Ferdinandea visited four German geologist - Philippi, Hoffman, Escher von der Lynt and Shults. "Approaching the island, they saw that it was a ring of the crater, which continued to emit toxins. Quietly went up the huge ball-shaped clubs of vapor, white as cotton wool, they made a post in the 2000 feet altitude. Every 2 - 3 minutes of this white mass cut through the black slag, which, like lightning, flashed with frightening rapidity, suddenly blurted out such a huge amount of slag that they formed a column, up to 600 p. in height and scattered at the top in the form of a sheaf. Departing from the crater of the stones were black, only occasionally escaped the bright lightning that were distributed in all directions. This eruption was not accompanied by the usual roar could be heard only the sound of colliding and falling back into the crater of the slag. It lasted continuously 8 - 10 minutes. At this time, an island in the eastern part of its top raised to 60 p. and had a diameter of 800 p. "(Fuchs). August 2 the British captured the island, and after that he visited many times. At the time of its greatest development of the island up to 2000 p. in circumference and ? 200. in height, and he abruptly rose from the sea floor, and most of its shore depth reached 700 r. The northeastern part of the crater collapsed, the crater filled with water which is constantly boiling. Strength of the eruption began to wane, and for 12 August, coast of Sicily was not visible vapor column. The island consisted of loose volcanic masses, slag, volcanic sand, volcanic ash, etc., only a few pieces of its component species have reached a foot in diameter. All of these volcanic rocks arranged in a typical system of layers: from the outside, they fell to the sea, inside the crater - the direction of the bokken. These loose masses could not withstand the corrosive effects of sea waves, the end of October the crater disappeared and the island a little raised himself above the sea surface, and only in one place rose a slight hill of volcanic sand and slag. By year end, it all disappeared. There is even a word that in place of the island has reached the sea at this time 24 blacks. in depth. This figure is hardly fair: at least at the end of 1833 there existed a dangerous shoal, and the bottom is formed by volcanic rocks, clearly visible through a thin layer of water. But this grounding did not last long. Does this story ended suddenly appeared and disappeared island, or is it just the beginning of the grand volcanic process, which involves the formation of a permanent island? We can not answer these questions, but the latter seems more likely: at least, a huge number of volcanic islands of different seas were formed under conditions similar to the appearance of the island Ferdinandea.
