Agricultural fields line much of the walls of a 2-km-wide caldera on the northwest side of Corvo Island. The walls reach about 200 m above the caldera floor, which contains several small, vegetated cinder cones and two shallow lakes. The 4 x 6 km island is located at the NW end of the Azores archipelago, west of the Mid-Atlantic Ridge. The Vila do Corvo flank eruption is the youngest known activity, dated about 80,000 years ago; it produced a lava flow that reached the ocean on the southern tip of the island.
