Graph showing depth of Halemaumau lava lake, Kilauea volcano

Graph showing the depth of the Halema‘uma‘u crater lava lake at Kīlauea Volcano's summit. Measurements began one day after the start of the eruption on December 20, 2020 and are updated by geologists making observations from the field. HVO field crews use a portable laser range finder to measure the vertical distance between points of known elevation and the lava lake surface. Frequent sets of repeat manual measurements were averaged and plotted to derive the lava lake depth.  

On January 8, 2021, a novel laser rangefinder was stationed at Kīlauea Volcano's summit. The fixed instrument continuously measures the distance to the lava lake surface, and telemeters data to HVO in real time. The raw data has been edited for this graph, with a running mean average filter of 3600 seconds. 

Variations in plotted depth can occur due to alternating field crews, the uneven surface of the lava lake, or laser rangefinder returns on gas rather than the lake surface.

Graph showing Average measurements of SO2 from Kilauea summit since 12 December 2020

Sulfur dioxide (SO2) emission rates measured using an upward-looking ultraviolet spectrometer. These data are collected by traversing the gas plume in a vehicle or helicopter, downwind of Halema‘uma‘u, generally within and/or southwest of Kīlauea caldera. Results from multiple traverses during a day are averaged to yield the emission rates shown here. Successful measurements depend on wind, weather, and staff availability. Values are preliminary and are subject to revision.
