Sullorsuaq Strait
Location within Greenland
Sullorsuaq Strait (old spelling: Suvdlorssuaq, Danish : Vaigat) is a strait on the western coast of Greenland.
Sullorsuaq Strait (old spelling: Suvdlorssuaq, Danish : Vaigat) is a strait on the western coast of Greenland.
The strait separates Nuussuaq Peninsula in the northeast from Qeqertarsuaq Island in the southwest. [1] The strait waterway connects inner Disko Bay in the southeast with Baffin Bay in the northwest. Qeqertarsuatsiaq Island is located in the northeastern mouth of the strait, where it opens into Baffin Bay. At the southeastern end, the large Alluttoq Island is located in the outlet of the strait, at the confluence with Disko Bay. [2]
Saqqaq is the only settlement in the area, located in the southern part on the shores of Nuussuaq Peninsula. The former coal mining settlement of Qullissat, founded in 1924, was located on the northeast coast of Disko Island and grew into one of Greenland's larger settlements. Qullissat was abandoned in 1972, and the entire northern coast of Disko Island is now uninhabited.
Archaeological excavations in Qilakitsoq on the northeastern shore revealed the existence of an ancient Arctic culture later named the Saqqaq culture, which is the archaeological designation of the earliest Palaeo-Eskimo culture of west and southeast part of Greenland. The natives inhabited the area of west-central Greenland between 2500 BCE and 800 BCE. [3]
Major landslides have struck Sullorsuaq Strait since prehistoric times, sometimes generating tsunamis or megatsunamis:
A tsunami is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions above or below water all have the potential to generate a tsunami. Unlike normal ocean waves, which are generated by wind, or tides, which are in turn generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water from a large event.
A megatsunami is a very large wave created by a large, sudden displacement of material into a body of water.

Volcanic islands and volcanoes on land frequently undergo large landslides/collapses, which have been documented in Hawaii for example. A recent example is Anak Krakatau, which collapsed to cause the 2018 Sunda Strait tsunami.
