Lava flow thickness 2018

Lava flow thickness 2018

Detailed Description

This preliminary thickness map of KÄ«lauea Volcano's 2018 lower East Rift Zone lava flows was calculated by subtracting pre-eruption ground surface elevations from post-eruption ground surface elevations mapped with USGS Unmanned Aerial System (drone) flights. The drones acquired 2,800 aerial photos from which 1.5 billion common points were automatically selected by Surface-from-Motion software. It is still preliminary because additional ground control points are needed to finalize the map.
