Mauna Loa 2022 lava flow digital elevation models and thickness maps

Mauna Loa volcano, Island of Hawaiʻi, erupted from November 27 to December 10, 2022, sending lava flows across the summit caldera (Mokuʻāweoweo) and into the upper Southwest Rift Zone, before focusing in the Northeast Rift Zone at fissure 3, sending a lava flow down the north flank that threatened a major highway. During the eruption, there was a need for updated terrain data to update syn-eruptive lava flow routing and runout forecasts, as well as to track emplaced lava thickness and volume. Following a successful deployment during the 2018 lower East Rift Zone eruption of Kīlauea volcano, Hawaii, the National Aeronautics and Space Administration supported rapid deployment of the Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) airborne GLISTIN-A instrument for three days of syn-eruptive acquisitions to measure topographic change using single-pass InSAR (December 7, 8, and 10, 2022). Digital elevation models (DEMs) from each flight line are available from the NASA Jet Propulsion Laboratory (JPL) at the California Institute of Technology. This data release provides mosaicked DEMs and lava flow thickness maps for three days of the eruption that were used to measure eruptive volume and time-averaged discharge rates.
