地質学的概要
The Eldey volcanic system is located on the northernmost part of the Reykjanes Ridge and is submarine with the exception of Eldey Island and the skerries (small rocky islands) Eldeyjardrangur, Geirfugladrangur, and Geirfuglasker. Maximum water depth within the system is about 250 m. Characteristic activity consists of explosive submarine basaltic eruptions. Six small eruptions have been located within this system during the last 1,100 years, the last occurring in 1926 CE. Bulletin reports that are included here cover a larger area of the Reykjanes Ridge south of Iceland without a clear source or enough evidence for a separate volcano entry.
Wikipedia の要約
英語版の要約Eldey is a small, uninhabited island about 13 kilometres off the coast of the Reykjanes Peninsula in southwest Iceland. Located west-southwest of Reykjavík, the island of Eldey covers an area of about 3 hectares, and rises to a height of 77 metres (253 ft). Its sheer cliffs are home to large numbers of birds, including one of the largest northern gannet colonies in the world, with around 16,000 pairs. This colony can now be watched live via two webcams that are located on top of the island.
