The island is located approximately 3,000 kilometers (1,900 miles) southeast of South Africa and 2,300 kilometers (1,400 miles) northwest of Antarctica. In this view from the International Space Station, only a part of the eastern coastline is visible (image center). The island is volcanic in origin and has a summit elevation of 775 meters (2,543 feet) above sea level. The Île aux Cochons stratovolcano is thought to have erupted within the past 12,000 years; however, no historical activity has been recorded. The summit elevation is high enough for the land surface to interact with cloud layers and winds flowing past the island, and two major cloud layers are visible. The lower, more uniform layer consists of rough...
