Global Volcanism Program | Image GVP-12572
The Groppo group contains several cones and lava flows, with a younger darker flow near the top of this December 2019 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 42 km across). Several phreatomagmatic craters are visible, with complex groups of overlapping vents and at least one possible maar. Several of the scoria cones have craters that experienced flank collapse or rafting during their eruptions, including the northernmost cone.
