Alluttoq Island (Danish: Arveprinsen Ejland) is a large 655 km² (252.9 sq mi), uninhabited^[1] island in Avannaata municipality in western Greenland, located in the northern part of Disko Bay, in the outlet of the Sullorsuaq Strait, east of Disko Island.^[2]

Settlement

Ataa, located on the eastern coast of the island, is an abandoned settlement, with the last families leaving the village around 1960. The closest populated settlements are Qeqertaq to the northeast, on an island off the Nuussuaq Peninsula, and Oqaatsut to the southeast, on the mainland.

History

Research indicates that megatsunamis generated by large landslides into Sullorsuaq Strait (known in Danish as Vaigat Strait) struck Alluttoq Island at least twice in prehistory. A wave that struck sometime around 5,650 BC had a run-up height of 41 to 66 metres (135 to 217 ft), and another that struck around 5,350 BC had a run-up height of 45 to 70 metres (148 to 230 ft).^[3]
