Plumeria Simulations of 20 December 2020 Kīlauea Volcano Eruption Plume This data release contains results of model simulations of a plume at Kilauea volcano that occurred on 20 December 2020. The ash-poor plume was produced when lava flowed into a water lake at the summit of Kilauea volcano. Simulations were conducted to constrain the conditions under which the plume rose to its observed height. The analysis and results are described in the accompanying paper: Cahalan RC, Mastin L, Van Eaton A, Hurwitz S, Smith AB, Dufek J, Solovitz SA, Patrick M, Schmith J, Parcheta C, Thelen W, Downs DT (2023 (in press)) Dynamics of the December 2020 ash-poor plume formed by lava-water interaction at the summit of Kīlauea Volcano, Hawaiʻi.

Samples were analyzed on Microtrac CAMSIZER® P4 and X2 instruments for grain size and shape data in the USGS Hawaiian Volcano Observatory (HVO) tephra lab. Data release includes sample descriptions, half phi grain size distributions, and statistical output from DECOLOG deconvolution modeling of grain size distributions. Grain size is reported using the sieve compatible Xcmin parameter (CAMSIZER® manual, 2020). Data of 2D shape parameter means of sphericity, Krumbein roundness and compactness of samples as well as for half phi grain size bins at 4, 3, 2, 1, 0, and -1 phi are also included.

These events included an unprecedented water lake and two prolonged episodes of lava lake activity. This data release includes images from a stationary thermal camera poised on the western caldera rim, with the camera providing a continuous record of the summit changes over this period. The thermal images provide an excellent observational record of the activity owing to the ability to see through thick volcanic fume, and the clarity with which they highlight active portions of the...

Both instruments were collocated with GNSS stations. The HOVL gravimeter was installed in 2010 and operated until 2018, when it was destroyed by summit collapse. The PUOC gravimeter was installed in 2013 and operated until 2018, when it was removed following the cessation of eruptive activity at Puʻu ʻŌʻō. Although both gravimeters have data gaps of varying lengths owing to equipment outages, the...

The intrusion of magma into Kīlauea’s lower East Rift Zone triggered draining of the summit lava lake and magma withdrawal from the shallow reservoir. This resulted in 62 subsequent collapse events at the summit between May and early-August 2018. Each collapse event released energy equivalent to a magnitude-5.3 earthquake. The total collapse volume was about 0.8 km^3, with subsidence of more than 500 m in some places.

Between May and August, while the summit caldera collapsed, a lava channel extended 11 kilometers (7 miles) from fissure 8 in Leilani Estates to Kapoho Bay, where it formed an approximately 3.5-square-kilometer (1.4-square-mile) lava delta along the coastline. Rapidly-deployed remote sensing techniques were vital in monitoring these events. Following the eruption, the U.S. Geological Survey (USGS) contracted the acquisition of rigorous airborne lidar surveys of Kīlauea Volcano's summit,...

For 2018, a Secacam Wild Vision Full HD camera with a 7mm focal length was located at 1717 m elevation approximately 15 m south of the Mauna Loa Strip Road within Hawaiʻi Volcanoes National Park, 19.475843°N, 155.363560°W (WGS84). The camera was pointed southeast to capture images of the Kīlauea caldera every two minutes. These images were used to calculate maximum plume heights within the full frame of the camera. For each two-minute image, the maximum plume heights above the Halemaʻumaʻu crater rim, and in the overall image, were calculated using the horizontal distance to...

Large amounts of sulfur dioxide gas (SO2) were released from the volcano’s East Rift Zone (ERZ) during the entire eruptive period, and from the Overlook vent at the summit of the volcano from 2008-2018. This data release presents ground-based estimates of SO2 emission rates from the two gas emission sources for the period 2008-2013. For the two-year period 2008-2010, the summit data have been revised from previously published emission rates (Elias and Sutton, 2012). During this era, very high emissions from the volcano’s newly active lava lake led to opaque plumes and challenges in accurately quantifying SO2 column...

For example, microgravity surveys between 1975-2008 measured residual gravity increases of up to 0.450 mGal across the volcano’s summit and have been interpreted as filling of void space by magma (Johnson and others, 2010). In March 2008 a new long-lived eruption began within Kīlauea’s Halema‘uma‘u crater (Wilson and others, 2008) which...
