Water-level data for the crater lake at the summit of Kīlauea Volcano, Island of Hawaiʻi, 2019–2020 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...

One of these crises occurred in 2014-2015, when lava erupting from Puʻuʻōʻō advanced north of the rift zone, towards the town of Pāhoa (Poland and others 2016; Brantley and others 2019). This slow-moving crisis unfolded over approximately four months, as pāhoehoe lava gradually flowed towards the town. In the end, the lava flow fortunately stalled at the edge of the residential area, destroying only one home. During the crisis, geologists at the U.S. Geological Survey (USGS) Hawaiian Volcano...

The opening stages of this eruptive sequence started on 30 April, when a magmatic dike began moving east from Puʻuʻōʻō, a cone with a central crater that was the vent region for Kīlauea’s 35-year middle East Rift Zone eruption starting in 1983. The rapid migration of magma from beneath Puʻuʻōʻō caused its crater floor to drop over 300 m. This data release includes a three-dimensional model of Puʻuʻōʻō and the collapse crater, constructed...

The dataset contains (1) an attributed polyline shapefile and (2) an attributed polygon shapefile with features that represent the outline and extent of the flow on 35 different dates.

Between May and September of that year, 24 fissures opened on the lower flank of the volcano, producing lava fountains and expansive lava flows that covered an area of 36 km2 (Neal and others, 2019; Zoeller and others, 2020). Effusion rates at the dominant vent, fissure 8, were often >100 m3 s-1, and the total eruptive volume is estimated at 0.9–1.4 km3 (Dietterich and others, 2021) making it one of the most voluminous effusive...

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...

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...

Lava erupted from 24 fissures on the lower East Rift Zone over four months, with high effusion rates (>100 m3 s-1) often supplying lava into channelized flows (Dietterich and others 2021). This effusion produced an extensive lava flow field, covering 36 km2 and creating 3.5 km2 of new land along the coast (Zoeller and others 2020). The eruption was notable for the sustained high effusion rates, which produced complex and prolonged evolution of the lava flow field,...

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...

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...

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...

At Kīlauea in August 2014, a spiny ʻaʻā flow erupted from the levee of a crusted perched lava lake that had been inactive for a month, and the surface of the lava lake subsided as the flow advanced downslope over the following few days. Topography constructed from oblique aerial photographs using structure-from-motion (SfM) software shows that the volume of the flow (~68,000 m3) closely matches the volume of subsidence of the crusted lava lake (~64,000 m3). The similarity of these volumes, along with the textural characteristics of the lava, shows that the lava that fed the flow had been stored...

This was followed shortly afterwards by the opening of a segment of fissures in the direction of the Southwest Rift Zone. These were mostly within the structural boundary of the caldera, so their location is denoted as ‘South Caldera,’ with the exception of a short fissure that extended into the uppermost Southwest Rift Zone. By November 28, activity had shifted to four fissures that opened in the upper Northeast Rift Zone (Lynn and others, 2023). By December 2, eruptive activity was focused from Northeast Rift Zone fissure 3A supplying lava...
