Continuous laser rangefinder measurements of lava lake and crater filling at the summit of Kilauea volcano, Island of Hawai`i, 2021-2024

The surface elevation of lava lakes is an important parameter that can provide insight on the underlying magma reservoir pressure as well as outgassing dynamics of the magmatic system (Patrick and others 2019a). Lava lake elevation may also be useful in forecasting potentially hazardous eruptions on a volcano’s flanks (Burgi and others 2014; Patrick and others 2015). Precise measurements of lava lake elevation have been challenging in the past, due to thick volcanic gas plumes and the inaccessibility of most lava lakes. New technologies, such as laser rangefinders, provides new opportunities to measure lava levels with high accuracy and sample rates (Patrick and others 2019b). In this data release, we include data from a continuous (1 Hz) laser rangefinder (Safran Vectronix LRF 7047) measuring the surface elevation of active lava lakes and the solidified crater floor at the summit of Kīlauea Volcano, Island of Hawaiʻi, from 2021 to 2024. These data span five summit eruptions, which gradually filled Halemaʻumaʻu crater with new lava (Mulliken and others 2024). These data may be useful for understanding lava lake behavior, as well as crater refilling processes. A detailed description of the methodology is included in Younger and others (2024). Related digital elevation models of the summit during this period are provided in Carr and others (2023). References Burgi PY, Darrah TH, Tedesco D, Eymold WK. 2014.
