Fayal volcano is capped by a 2-km-wide, 400-m-deep summit caldera, seen here from its southern rim. A small pyroclastic cone (center) and a dark lake (right) can be seen on the floor of the caldera. The caldera was formed incrementally, beginning with a large eruption about 1,000 years ago. Thick airfall-pumice and pyroclastic-flow deposits related to this eruption cover the island.
