The Delarof Islands, a subgroup of the Andreanof Islands, constitute the westernmost islands of the latter group.

The largest islands in the group are, from west to east, Gareloi, Tanaga, Kanaga, Adak, Kagalaska, Great Sitkin, Atka, Amlia, and Seguam.

The islands are usually foggy and are treeless because of the almost constant wind. They were named for the Russian navigator, Andreian Tolstyk, who was the first to explore the islands in 1761.

There were several United States military bases on the islands during World War II. The bases on Adak were enlarged and made permanent after the war but were closed in 1995.

The islands are particularly prone to earthquakes, often many with a magnitude of over 5 occur each day.
