Unalaska Island in the Aleutian Islands.

The Aleutian Islands from 32,000 feet (9,700 m).

Active Aleutian volcanoes.

The islands, known before 1867 as the Catherine Archipelago, comprise five groups (east to west)

• the Fox Islands
• Islands of Four Mountains
• Andreanof Islands
• Rat Islands, and
• Near Islands

All five are located between 51° and 55° N latitude and 172° E and 163° W longitude.^[8] The largest islands in the Aleutians are Attu (the farthest from the mainland), and Unalaska, Umnak, and Unimak in the Fox Islands. The largest of those is Unimak Island, with an area of 1,571.41 mi² (4,069.9 km²), followed by Unalaska Island, the only other Aleutian Island with an area over 1,000 square miles (2,600 km²).
The axis of the archipelago near the mainland of Alaska has a southwest trend, but at Tanaga Island (about 178° W) 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 much seismic activity, but are still habitable; the Aleutians lie between the Pacific and North American tectonic plates.^{[citation needed]} 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.^[9]
The great majority of the islands bear evident marks of volcanic origin, and there are numerous volcanic cones on the north side of the chain, some of them active; many of the islands, however, are not wholly volcanic, but contain crystalline or sedimentary rocks, and also amber and beds of lignite. The coasts are rocky and surf-worn, and the approaches are exceedingly dangerous, the land rising immediately from the coasts to steep, bold mountains.^[9]
These volcanic islands reach heights of 6,200 feet (1,900 m). Makushin Volcano (5,691 feet (1,735 m)) on Unalaska Island, is not quite visible from within the town of Unalaska, though the steam rising from its cone is visible on a (rare) clear day. Residents of Unalaska need only to climb one of the smaller hills in the area, such as Pyramid Peak or Mt. Newhall, to get a good look at the snow-covered cone. The volcanic Bogoslof and Fire Islands, which rose from the sea in 1796 and 1883 respectively, lie about 30 miles (50 km) west of Unalaska Bay.^[9]
In 1906, a new volcanic cone rose between the islets of Bogoslof and Grewingk, near Unalaska, followed by another in 1907. These cones were nearly demolished by an explosive eruption on September 1, 1907.^[9] Newly found information in 2017, the volcanic cone erupted sending ash and ice particles 30,000 feet (9000 m) in the air.^[10]
