Oblique overhead view of the Kilauea Caldera Summit, Hawaii

This oblique overhead view of the Kilauea Caldera Summit, Big Island, Hawaii, was collected during the volcanic eruption event in 2018.  This comparison highlights areas of subsidence between the dates of June 13 and June 21.  The locations shown in the red depict high levels, 70-100 meters, of change.  The point clouds were generated from a photogrammetric collection of overlapping imagery using a Ricoh GR II camera on a FireFly6 Pro UAS platform.
