The 108-km-wide Nunivak Island volcanic field in the Bering Sea off Alaska is shown in this October 2019 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 96 km across). There are around 60 scoria cones and four maars across the island, with lava flows 3-15 m thick and less than 3.5 km long forming much of the Island surface.
