In the Azores archipelago west of the Mid-Atlantic Ridge is the 12 x 17 km Flores Island, shown in this February 2018 Planet Labs satellite image monthly mosaic (N is at the top). Initially a submarine volcano, the island formed through the eruption of different vents, forming cones, craters, maars, and associated eruption products like lava flows.
