During 2018, Kīlauea Volcano, on the Island of Hawaiʻi, had a large effusive eruption (~1 cubic kilometer of lava) on the lower East Rift Zone that caused widespread destruction (Neal and others, 2019; Dietterich and others, 2021). This lower flank eruption was accompanied by one of the largest collapses of the summit caldera in two hundred years, with portions of the caldera floor subsiding more than 500 m (Anderson and others, 2019; Neal and others, 2019). On July 25, 2019, approximately one year after the summit collapse sequence, a small pond of water was first observed in the deepest portion of the collapse pit, within Halemaʻumaʻu crater (Nadeau and others, 2020). The water level rose gradually over the...
We depict changing eruptive features within the summit caldera of Kīlauea volcano, Island of Hawaiʻi with rapid-response digital elevation models (DEMs) acquired since a series of caldera-filling effusive eruptions began on December 20, 2020. These eruptions follow the caldera collapse of 2018, with new lava progressively filling the approximately 1-cubic-kilometer pit that formed between May and August of that year. The majority of the provided DEMs were constructed via structure-from-motion (SfM) photogrammetry from either helicopter or uncrewed aircraft system (UAS) overflight images, with the remainder constructed via terrestrial laser scanning (TLS) from the Halemaʻumaʻu crater rim. These data were collected...

In May 2018, the onset of new eruptive activity on the lower flank of Kīlauea Volcano, Hawaiʻi, accompanied the draining of the lava lake at the summit, 40 km upslope. The lava lake draining lasted over seven days, and transitioned into the largest collapse event at the summit of Kīlauea in over 200 years, with the paired flank and summit activity marking a historic episode in the modern record of Kīlauea. We present two important datasets that characterize draining of the Kīlauea summit lava lake in 2018. First, we present high-precision elevation data of the lava lake surface measured by an industrial laser rangefinder. To our knowledge, this is the highest-precision lava lake elevation data ever collected over...
This data release includes measurements of the surface elevation of the lava lake within Halemaʻumaʻu crater, at the summit of Kīlauea Volcano, during the 2008-2018 summit eruption (Patrick and others, 2021). The data were measured by several instruments (laser rangefinder, webcams, lidar) and are compiled here to provide the most complete dataset yet available on the elevation of Kīlauea’s 2008-2018 summit lava lake. The measurement intervals range from 1 s to 1 day, with most of the 9-year period covered by hourly measurements. The dataset begins with daily measurements of the emergent lake in 2009 and 2010. After 2010, continuous lake activity was tracked with hourly measurements of lava level that continued...
In 2018, a large effusive eruption on the lower flank of Kīlauea Volcano was associated with collapse and subsidence of the summit caldera floor (Neal and others, 2019). The bottom of Halemaʻumaʻu, a crater nested within the summit caldera, subsided by more than 500 m. In July 2019, water was observed ponding on the deepest part of the Halemaʻumaʻu crater floor and the water rose and enlarged in area steadily over the next 16 months (Ingebritsen and others, 2020; Nadeau and others, 2020; Patrick and others, 2021). During the course of the rise, the lake surface appearance was highly dynamic and segmented, showing regions of variable color that changed from day to day (Nadeau and others, 2020). In June 2020 staff...

Data Description Campaign microgravity surveys have been conducted at Kīlauea, Hawai‘i (USA), since 1975 (Dzurisin and others, 1980) and, when combined with deformation measurements, enable insights into mass change within the volcano (Jachens and Eaton, 1980; Johnson, 1992; Kauahikaua and Miklius, 2003; Johnson and others, 2010; Bagnardi and others, 2014; Poland and others 2019). 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...
