Corvo Island, literally the Island of the Crow, is the smallest and the northernmost island of the Azores archipelago and the northernmost in Macaronesia, with a population of approximately 468 inhabitants constituting the smallest single municipality in Azores and in Portugal. This island, which sits in the North American Plate, formed from a 5 km diameter central volcano that emerged around 730,000 years ago, whose central cone was approximately 1000 meters in altitude.
