About this work
This image shows a collapse feature on the southeastern flank of the volcano. The circular/scalloped margin of the collapse is typical for ceiling collapse into a lava tube. However, the potential lava tube is perpendicular to the surface flows. The linear nature and relationship to the surface flows likely indicate that a preexisting tectonic graben occurred here and hosted lava flows that may have become lava tube flows.
