Kīlauea

Recent Eruption

Kīlauea Volcano began erupting on December 20, 2020, at about 9:30 p.m. HST in Halema‘uma‘u crater. The last activity on the lava lake surface was observed on May 23 and on May 26, 2021, the USGS Hawaiian Volcano Observatory lowered the Volcano Alert Level for ground-based hazards from WATCH to ADVISORY and the Aviation Color Code from ORANGE to YELLOW.

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.

Color map of lava lake at volcano summit

This map of Halema‘uma‘u at the summit of Kīlauea shows 20 m (66 ft) contour lines (dark gray) that mark locations of equal elevation above sea level (asl). The map shows that the lava lake filled 229 m (752 ft) of the crater, to an elevation of 747 m (2450 ft) asl, from the beginning of the eruption on December 20, 2020, through May 13, 2021. Over this period, a total of 41 million cubic meters (11 billion gallons) of lava was erupted into the crater, filling approximately 5 percent of the volume that collapsed within the caldera during the 2018 eruption. The graphic at the bottom shows topographic profiles from west to east across the caldera before 2018, shortly after 2018, and as of May 13, 2021, along with the 2019-2020 Halema‘uma‘u water lake. The last activity on the lava lake surface was observed on May 23 and on May 26, 2021, the USGS Hawaiian Volcano Observatory lowered the Volcano Alert Level for ground-based hazards from WATCH to ADVISORY and the Aviation Color Code from ORANGE to YELLOW. USGS map.
