Great Sitkin Island (Aleut: Sitх̑naх̑;[1] Russian: Большой Ситкин) is a volcanic island in the Andreanof Islands of the Aleutian Islands of Alaska. The island covers a total area of 60 square miles (160 km2) and lies slightly north of a group of islands which are located between Adak Island and Atka Island.

The northern portion of the island is dominated by the complex Great Sitkin Volcano which rises to a height of 5,710 feet (1,740 m). The island is 18 kilometres (11 mi) long and 16.94 kilometres (10.53 mi) wide.

History

Great Sitkin was the site of a fuel depot during

Liberty Ship Ekaterini G. (formerly Josiah G. Holland) ran aground after losing her propeller in heavy seas.[5] All crewmen were rescued, though 2 were injured and one, Sotiris Mendrinos, later died of his injuries. [6] The ship was declared a constructive total loss and remains aground on the western side of the island. On December 11, 1973, a Douglas DC-6 crashed on the island, killing all 10 people on board. [7]

The most recent eruption of Great Sitkin volcano started on 26 May 2021 (UTC time), with an explosive eruption that lasted for about two minutes.[8] The effusive lava flow didn't start until late July 2021.

Geology

With the eruption that started on 26 May 2021, studies have documented the spatiotemporal migration of earthquake activities before and after the eruption.[9] The study, with seismic imaging of the velocity structure, reveals two magma reservoirs at different depths and locations relative to the volcano edifice.[9] The spatial and temporal migration of seismicity back and forth between the northwestern and southeastern island may be explained by the alternating eruptive activity of the two imaged reservoirs.
