- Jólnir
Jólnir was formerly a
volcanic island south ofIceland . It emerged from the ocean as a result of tectonic activity in July, 1966. Oceanicerosion cyclically wore down the new land as it formed, and the island sank below the surface several times.It was named for Jólnir, a Norse god (usually identified as a second name for
Odin ).Jolnir's formation is closely linked to that of neighboring volcanic island,
Surtsey , which emerged in 1963.Volcanic eruption s occurred in much of the surrounding water, but newly formed land was subject to oceanicerosion and many small islands washed away. By 1966, Jólnir had broken the surface, and changing composition of the emerging material resulted in hardier rock forms resistant to erosion. The volcanic cone reached 70 meters above sea level, but even this landmass eventually gave way to the eroding ocean waves.After activity ceased on 8 August 1966, it was rapidly eroded, and dropped below sea level during October 1966.
