Details for: Terceira
The Monte Brasil pyroclastic cone rises above the historic city of Angra do Heroísmo on the south-central coast of Terceira Island. Terceira contains four stratovolcanoes constructed along a prominent ESE-WNW-trending fissure zone that cuts across the island. Historically active Santa Barbara volcano at the western end of the island is truncated by two calderas. Historical eruptions at Terceira have occurred from Pico Alto, the fissure zone between Pico Alto and Santa Barbara, and from submarine vents west of Santa Barbara.
