The Aleutian Islands (possibly from Chukchi aliat, "island") are a chain of more than 300 small volcanic islands forming an island arc in the Northern Pacific Ocean, occupying an area of 6,821 sq mi (17,666 km²) and extending about 1,200 mi (1,900 km) westward from the Alaska Peninsula toward the Kamchatka Peninsula. Crossing longitude 180°, they are the westernmost part of the United States (and technically also the easternmost; see Extreme points of the United States). Nearly all the archipelago is part of Alaska and usually considered as being in the "Alaskan Bush", but at the extreme western end the small, geologically-related, but remote Komandorski Islands, are in Russia. The islands, with their 57 volcanoes, are in the northern part of the Pacific Ring of Fire.

Geography

---

The islands, known before 1867 as the Catherine Archipelago, comprise five groups: the Fox, Islands of Four Mountains, Andreanof, Rat and Near island groups. They are all located between 52° and 55° N latitude and 172° E and 163° W longitude.

The axis of the archipelago near the mainland of Alaska has a southwest trend, but near the 129th meridian its direction changes to the northwest. This change of direction corresponds to a curve in the line of volcanic fissures that have contributed their products to the building of the islands. Such curved chains are repeated about the Pacific Ocean in the Kuril Islands, the Japanese chain and in the Philippines. All these island arcs are at the edge of the Pacific Plate and experience a lot of seismic activity, but are still habitable; the Aleutians lie between the Pacific and North American tectonic plates. The general elevation is greatest in the eastern islands and least in the western. The island chain is a western continuation of the Aleutian Range on the mainland.
