evidence: Several volcanic seamounts and hundreds of volcanic cones rise above the floor of the southern Mozambique Channel. A few of the larger volcanic features are capped with flat expanses of carbonate that breach the water’s surface, forming low-lying coralline islands. Europa is one such island. Europa Island is the focus of this image, acquired on April 3, 2022, with the Operational Land Imager-2 (OLI-2) on Landsat 9. It is part of an overseas French territory that includes the Îles Éparses, or "scattered islands," dispersed around Madagascar. Mozambique on the African mainland lies about 500 kilometers (300 miles) to the west, and Madagascar sits about 300 kilometers (200 miles) to the east. Europa Island spans about 28 square kilometers, making it the largest of the Îles Éparses. It was initially an atoll that became exposed at the sea surface around 90,000 years ago. The atoll progressively filled in, and it slowly transformed into the island we know today.
