Ireland also lies near the axis of this great volcanic area, reaching from the Canaries to Iceland, and it has been many times in the past the seat of disturbance. The ancient annals contain numerous accounts of eruptions, preceded by volcanic action. In 1490, at the Ox Mountains, Sligo, one occurred by which one hundred persons and numbers of cattle were destroyed; and a volcanic eruption in May, 1788, on the hill of Knocklade, Antrim, poured a stream of lava sixty yards wide for thirty-nine hours, and destroyed the village of Ballyowen and all the inhabitants, save a man and his wife and two children. ("Amer. Cyclop.," art. Ireland.) While we find Lisbon and Ireland, east of Atlantis, subjected to these great earthquake shocks, the West India Islands, west of the same centre, have been repeatedly visited in a similar manner. In 1692 Jamaica suffered from a violent earthquake. The earth opened, and great quantities of water were cast out; many people were swallowed up in these rents; the earth caught some of them by the middle and squeezed them to death; the heads of others only appeared above-ground. A tract of land near the town of Port Royal, about a thousand acres in extent, sunk down in less than one minute, and the sea immediately rolled in. The Azore Islands are undoubtedly the peaks of the mountains of Atlantis. They are even yet the centre of great volcanic activity. They have suffered severely from eruptions and earthquakes. In 1808 a volcano rose suddenly in San Jorge to the height of 3500 feet, and burnt for six days, desolating the entire island. In 1811 a volcano rose from the sea, near San Miguel, creating an island 300 feet high, which was named Sambrina, but which soon sunk beneath the sea. Similar volcanic eruptions occurred in the Azores in 1691 and 1720. Along a great line, a mighty fracture in the surface of the globe, stretching north and south through the Atlantic, we find a continuous series of active or extinct volcanoes. In Iceland we have Oerafa, Hecla, and Rauda Kamba; another in Pico, in the Azores; the peak of Teneriffe; Fogo, in one of the Cape de Verde Islands: while of extinct volcanoes we have several in Iceland, and two in Madeira; while Fernando de Noronha, the island of Ascension, St. Helena, and Tristan d'Acunha are all of volcanic origin.
