Caldeira - Faial (Azores)
Caldeira - Faial (Azores) -

Along with other islands in the Azores archipelago, Faial is of volcanic origin and is close to the tectonic divide between the European and North American Plates. Indeed, the island can be considered (from a geophysical perspective) the westernmost point of Europe (the two islands west of Faial, Flores and Corvo, are already on the American plate).

Visually, the island is characterized as an irregular pentagon, that occupies an area of approximately 173 square kilometres (67 sq mi), and formed along a leaky transform fault extending from the mid-Atlantic Ridge to the Hirondella faults. This is the same fault that bisects the remainder of the Central Group of islands along a west-northwest to east-southeast orientation. Although formed by complex volcanological events, the current landmass is dominated by the crater of its central stratovolcano with relatively gently sloping flanks, showing little sign of major erosion.
