The 2018 Kīlauea eruption and caldera collapse generated intense cycles of seismicity tied to repeated large seismic (Mw ~5) collapse events associated with magma withdrawal from beneath the summit. To gain insight into the underlying dynamics and aid eruption response, we applied waveform-based earthquake detection and double-difference location as the eruption unfolded. Here, we augment these rapid results by grouping events based on patterns of correlation-derived phase polarities across the network. From April 29 to August 6, bracketing the eruption, we used ~2800 events cataloged by the Hawaiian Volcano Observatory to detect and precisely locate 44,000+ earthquakes. Resulting hypocentroids resolve complex,...
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...
The youngest and largest island in the State of Hawaii—the Island of Hawai‘i—is formed by five volcanoes, three of which have erupted within recent geologic history: Mauna Loa, Kīlauea, and Hualālai. This data release provides a chronology for activity and impacts at Mauna Loa, Kīlauea, and Hualālai over approximately the past two and a half centuries. This data release includes a word document, “HI_volcanoes_chronology_description,” that describes the data compilation process and provides simple summary tables of eruptive activity and maps. A CSV file contains the compiled eruption chronology data for all volcanoes—"HI_volcanoes_chronology_data”—references for which are provided in a separate CSV file titled “HI_volcanoes_chronology_references.”...

Volcanology,
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...
This data release provides volcanic plume heights from the summit of Kīlauea Volcano for 2008-2015, and during the eruptive events of 2018. 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...

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...
