The Eastern Pacific Islands are mostly volcanic, large, and have high elevations.

The Haida Gwaii archipelago (1,500 km2; Canada), the Channel Islands (909 km2; USA), the Baja California Pacific Islands (943 km2; Mexico), the Gulf of California Islands (4,076 km2; Mexico), the Revillagigedo Archipelago (155 km2; Mexico), Coiba Island (503 km2; Panama), Cocos Island (23.48 km2; Costa Rica), Malpelo Island (3.5 km2; Colombia), the Galapagos Archipelago (8,010 km2; Ecuador), and the Juan Fernandez Archipelago (100 km2; Chile) are heterogeneous examples of the islands that lie in the Eastern Pacific. Yet, all of them are significant centers of biodiversity and endemism.

Due to their outstanding universal value, many of these islands and archipelagos have been declared as World Heritage Sites by UNESCO. Accounting for 40% of the Earth’s surface, the Pacific Ocean harbors 15 World Heritage Sites, six of which encompass islands in the Eastern Pacific. The Galápagos, Cocos, Malpelo, Gorgona and Coiba islands make up the world’s densest cluster of marine UNESCO World Heritage Sites, collectively constituting the Eastern Tropical Pacific Seascape.
