Ile Amsterdam (Ile Amsterdam et Ile Saint-Paul): less than one-half the size of Washington, DC;

Ile Saint-Paul (Ile Amsterdam et Ile Saint-Paul): more than 10 times the size of the National Mall in Washington, DC;

Iles Crozet: about twice the size of Washington, DC;

Iles Kerguelen: slightly larger than Delaware;

Bassas da India (Iles Eparses): land area about one-third the size of the National Mall in Washington, DC;

Europa Island (Iles Eparses): about one-sixth the size of Washington, DC;

Glorioso Islands (Iles Eparses): about eight times the size of the National Mall in Washington, DC;

Juan de Nova Island (Iles Eparses): about seven times the size of the National Mall in Washington, DC;

Tromelin Island (Iles Eparses): about 1.7 times the size of the National Mall in Washington, DC

Ile Amsterdam et Ile Saint-Paul: oceanic with persistent westerly winds and high humidity;

Iles Crozet: windy, cold, wet, and cloudy;

Iles Kerguelen: oceanic, cold, overcast, windy;

Iles Eparses: tropical

Ile Amsterdam (Ile Amsterdam et Ile Saint-Paul): a volcanic island with steep coastal cliffs; the center floor of the volcano is a large plateau;

Ile Saint-Paul (Ile Amsterdam et Ile Saint-Paul): triangular in shape, the island is the top of a volcano, rocky with steep cliffs on the eastern side; has active thermal springs;

Iles Crozet: a large archipelago formed from the Crozet Plateau is divided into two groups of islands;

Iles Kerguelen: the interior of the large island of Ile Kerguelen is composed of high mountains, hills, valleys, and plains with peninsulas stretching off its coasts;

Bassas da India (Iles Eparses): atoll, awash at high tide; shallow (15 m) lagoon;

Europa Island, Glorioso Islands, Juan de Nova Island: low, flat, and sandy;

Tromelin Island (Iles Eparses): low, flat, sandy; likely volcanic seamount

Ile Amsterdam and Ile Saint-Paul are inactive volcanoes; Iles Eparses subject to periodic cyclones; Bassas da India is a maritime hazard since it is under water for a period of three hours prior to and following the high tide and surrounded by reefs

volcanism: Reunion Island - Piton de la Fournaise (2,632 m), which has erupted many times in recent years including 2010, 2015, and 2017, is one of the world's most active volcanoes; although rare, eruptions outside the volcano's caldera could threaten nearby cities

islands' component is widely scattered across remote locations in the southern Indian Ocean

Bassas da India (Iles Eparses): atoll is a circular reef atop a long-extinct, submerged volcano;

Europa Island and Juan de Nova Island (Iles Eparses): wildlife sanctuary for seabirds and sea turtles;

Glorioso Island (Iles Eparses): islands and rocks are surrounded by an extensive reef system;

Tromelin Island (Iles Eparses): climatologically important location for forecasting cyclones in the western Indian Ocean; wildlife sanctuary (seabirds, tortoises)
