Background

The island is composed of a complex large andesitic-to-trachytic stratovolcano that contains a 2-km-wide summit caldera. Thick deposits of trachytic airfall pumice, pyroclastic flows, and lahars related to formation of the caldera blanket the island. Formation of the steep-walled 500-m-deep caldera was followed by construction of fissure-fed basaltic lava fields and small volcanoes that form a peninsula extending to the west. This area is covered by the youngest volcanic products on the island and has been the source of all historical eruptions. A dramatic submarine eruption at Capelinhos during 1957-58, the best-studied of historical eruptions in the Azores, created a new island that soon merged with the western peninsula.
