Eldey Volcano — Iceland

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.
