By studying deep-sea lava formations, MBARI’s submarine volcanism lab hopes to gain insight into potentially destructive eruptions on land or in shallow water. This image was taken with ROV Doc Ricketts’ video camera on the 2011 lava flow at Axial Volcano on the Juan de Fuca Ridge. It is the collapsed roof over a drained channel on the flow. There are living bacterial mat and hydrothermal clays on the lava flow surface.
