| Volcanic island off the coast of Iceland | WIKI |
| Surtsey ("Surtr's island" in Icelandic, Icelandic pronunciation:xc2xa0xe2x80x8b[xcbx88sxcax8frxccxa5(t)sxcbx8ceixcbx90]) is a volcanic island located in the Vestmannaeyjar archipelago off the southern coast of Iceland. | WIKI |
| [1] It was formed in a volcanic eruption which began 130 metres (430 feet) below sea level, and reached the surface on 14 November 1963. | WIKI |
| The undersea vents that produced Surtsey are part of the Vestmannaeyjar submarine volcanic system, part of the fissure of the sea floor called the Mid-Atlantic Ridge. | WIKI |
| The eruption that created Surtsey also created a few other small islands along this volcanic chain, such as Jxc3xb3lnir and other, unnamed peaks. | WIKI |

| The sea floor at the eruption site is 130 metres (430 feet) below sea level, and at this depth volcanic emissions and explosions would be suppressed, quenched and dissipated by the water pressure and density. | WIKI |
| The first noticeable indications of volcanic activity were recorded at the seismic station in Kirkjubxc3xa6jarklaustur, Iceland from 6 to 8 November, which detected weak tremors emanating from an epicentre approximately west-south-west at a distance of 140xc2xa0km (87xc2xa0mi), the location of Surtsey. | WIKI |
| Instead, they encountered explosive eruptions giving off black columns of ash, indicating that a volcanic eruption had begun to penetrate the surface of the sea. | WIKI |
| By early 1964, though, the continuing eruptions had built the island to such a size that sea water could no longer easily reach the vents, and the volcanic activity became much less explosive. | WIKI |
| These resulted in a hard cap of extremely erosion-resistant rock being laid down on top of much of the loose volcanic pile, which prevented the island from being washed away rapidly. | WIKI |
| Subsequent volcanic activity[edit] | WIKI |
| Eruptions at Syrtlingur were much smaller in scale than those that had built Surtsey, with the average rate of emission of volcanic materials being about a tenth of the rate at the main vent. | WIKI |
| It was named Jxc3xb3lnir, and over the following eight months it appeared and disappeared several times, as wave erosion and volcanic activity alternated in dominance. | WIKI |
| Surtsey is a new island formed by volcanic eruptions in 1963-67. | UNESCO |
| Criterion (ix): Ongoing biological and ecological processes: Surtsey was born as a new volcanic island in 1963-67 and since that time has played a major role in studies of succession and colonisation. | UNESCO |
