Between March 2002 and May 2011 periodic water level measurements were made in the well on the summit of Kīlauea Volcano using a 2,000-foot calibrated electric tape (Waterline Envirotech Ltd.) with graduations of 0.01 foot. Water level measurements resumed in March 2018. Calibration of the electric tape at the USGS Hydrologic Instrumentation Facility (HIF) in November 2018 revealed a displacement of 0.29 feet over 1,980 feet of the electric tape. We therefore estimate that the accuracy of the water level measurements is 0.3 foot (±9 cm). Water level measurements were referenced to the top of the wellhead, located at 1103 meters above sea level at the time of drilling in 1973.

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.

A total of 100 samples were collected from two proximal sections of Keanakākoʻi, Tephra unit D deposits. 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. Please refer to associated...

Chemistry and Isotope Data Sample Collection: Water samples were collected from approximately 100 feet (30 meters) below the water table using either a 4 foot or 6 foot long stainless-steel bailers with an inner diameter of 0.5 in. Samples for anion concentration measurements were poured into 60 ml polypropylene bottles through 0.45mm pore-diameter filter. Raw (unfiltered, unpreserved) samples for oxygen-18 and deuterium isotope analyses were stored in 30 ml glass bottles. Sample Analyses: The concentrations of sulfate (SO42-), chloride (Cl-), and fluoride (F-) in samples collected until October 2003 were determined with a Dionex DX-300 ion chromatograph, and since October 2003 with a Dionex ICS-2000 ion chromatograph...

Following the 2018 collapses of the caldera floor at the summit of Kīlauea Volcano (Anderson and others, 2019; Neal and others, 2019), the enlarged and deepened depression hosted a variety of volcanic activity between 2019 and 2022. 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...

This Data Release contains continuous gravity records from two instruments on Kīlauea Volcano, Hawaiʻi: the HOVL gravimeter, located on the east rim of Halemaʻumaʻu Crater directly above the 2008-2018 summit eruptive vent, and the PUOC gravimeter, located on northern rim of Puʻu ʻŌʻō crater on Kīlauea’s East Rift Zone. 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...
This dataset contains Unoccupied Aircraft Systems (UAS) footage from the 2018 summit collapse of Kīlauea Volcano, Island of Hawai‘i. 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. There are 73 UAS videos in this publication, recorded from May 19 to September 5, which have been separated into subpages by month. Sub-pages for each month also contain...

This dataset contains Unoccupied Aircraft Systems (UAS) footage from the 2018 eruption of Kīlauea Volcano’s lower East Rift Zone (LERZ), Island of Hawai‘i. The four-month-long eruption, from May 3 to September 5, produced lava flows that destroyed 723 structures, inundated 35.5 km2 of land, and added 3.5 km2 of new land to the Island of Hawai‘i. There are 1178 UAS videos in this publication, recorded from May 27 to September 8, which have been separated into sub-pages by month. Videos taken during each month are separated into zipped files by date (YYYY/MM/DD) and location. Sub-pages for each month also contain a ReadMe text file with information pertaining to the videos, including flight end time, video duration,...
The 2018 eruption of Kīlauea Volcano on the Island of Hawaiʻi saw the collapse of a new, nested caldera at the volcano’s summit, and the inundation of 35.5 square kilometers (13.7 square miles) of the lower Puna District with lava. 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,...

High-resolution (plus or minus (±) 0.1°C) temperature measurements were accomplished with a platinum resistance temperature (PRT) probe. The PRT probe, suspended from an armored logging cable, was lowered into the well over a sheave with a portable hand-cranked reel. Attached to the sheave were both mechanical and digital depth counters. The PRT output and digital depth counter were connected to an electronic data logger programmed to display and record the temperature and depth values at 5-second intervals. The temperature logs were conducted from the top of the water column downward at 10 foot increments so that the established thermal equilibrium of the water column was least disturbed by logging. Once the target...
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...

Kīlauea, on the Island of Hawai`i is one of the world’s most active volcanoes and it hosts one of the densest volcano monitoring networks. A deep well on the southwest rim of Kilauea’s caldera, often referred to informally as the “NSF Well” or the “Keller Well” was drilled in 1973 to a depth of 1,262 meters from an elevation of 1,103 meters. The ultimate goal of the drilling project was to “test predictions made from surface-based geophysical surveys and seek evidence of a hydrothermal system over a known magma body” (Zablocki et al., 1974; Keller et al., 1979). Following drilling the open hole filled up with drilling mud and in October 1998 the hole was cleared of the mud using a large pump to a depth of about...
