Raoul Island in the Kermadec Islands has two main calderas, one in the center of the island (Raoul Caldera) and one forming the linear western shoreline (Denham Caldera), shown in this November 2019 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 11 km across). The Blue (upper) and Green (lower) lakes are within Raoul Caldera, with the 1964 crater along the NW edge of the Green Lake.
