Volcanic ash geochemistry and leachate analyses from the 2008 opening of Halemaʻumaʻu crater, Kīlauea Volcano, Hawaiʻi Volcanic ash geochemistry and leachate analyses from the 2008 opening of Halemaʻumaʻu crater, Kīlauea Volcano, Hawaiʻi
On March 19, 2008, an explosive eruption occurred at the summit of Kīlauea Volcano for the first time since 1924. This event marked the beginning of a continuous summit eruption that lasted until the 2018 Kīlauea lower East Rift Zone eruption (Neal and others, 2019). The March 19 explosive eruption excavated a crater approximately 35 meters wide and scattered volcanic tephra over a 30...
Timelapse and webcam images of the 2022 eruption of Mauna Loa, Island of Hawaiʻi Timelapse and webcam images of the 2022 eruption of Mauna Loa, Island of Hawaiʻi
The 2022 eruption of Mauna Loa volcano, Island of Hawaiʻi, was the first eruption on the volcano since 1984, producing a 17 km lava flow that threatened a major highway (Mulliken and others 2024; Zoeller and others 2024). The eruption began with lava fountaining in the summit caldera (Mokuʻāweoweo) at 23:21 HST on November 27, transitioning to vents on the Northeast Rift Zone (NERZ) by...
Data Support for a Statistical Perspective on the Petrologic Utility of Polyphase Groundmass Compositions Inferred Via Defocused Beam Electron Probe Microanalysis Data Support for a Statistical Perspective on the Petrologic Utility of Polyphase Groundmass Compositions Inferred Via Defocused Beam Electron Probe Microanalysis
This dataset contains major and trace element compositions for a sample of basalt recovered from Rangitoto Island, New Zealand. Both bulk rock and microanalytical observations are made and presented. Electron probe microanalysis (EPMA) results detail the compositions of individual phases within the basalt including olivine, clinopyroxene, plagioclase feldspar, glass, and polyphase...
Digital elevation model of the lava dome in the crater of Mount St. Helens, June 23, 1982 Digital elevation model of the lava dome in the crater of Mount St. Helens, June 23, 1982
The catastrophic, explosive eruption of Mount St. Helens, Washington, on May 18, 1980, is the most well-known eruption of the volcano. Less well known is the May 18 eruption marked the beginning of a period of eruptive activity that lasted through 1986. Beginning in October 1980, a series of 17 dome-building episodes added millions of cubic meters of lava to the crater floor. Most of the...
Sample details and near-real-time ED-XRF data collected during the 2020-2023 Halema‘uma‘u eruptions of Kīlauea volcano, Island of Hawaiʻi Sample details and near-real-time ED-XRF data collected during the 2020-2023 Halema‘uma‘u eruptions of Kīlauea volcano, Island of Hawaiʻi
A limited suite of samples for the 2020–2023 Kīlauea eruptions within Kaluapele (the summit caldera) were collected by the U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO) field teams from within a publicly closed area of Hawai‘i Volcanoes National Park in cooperation with the National Park Service. This data release presents sample metadata, whole rock ED-XRF, whole rock WD...

Tiltmeter data from Kīlauea stations (ESC, IKI, JKA, KAE, POC, POO, SDH, SMC, UWE) from January 1 to December 31, 2021. These data were collected in 2021 by Andria P. Ellis of the USGS Hawaiian Volcano Observatory. The authors thank Sarah Conway for conducting many of clock resets for these tiltmeters in 2021.
Laser Rangefinder Data for Surficial Mass Movements in the Cascades Laser Rangefinder Data for Surficial Mass Movements in the Cascades
A laser rangefinder was used to record surficial mass movements at Cascades volcanoes and an experimental debris flow flume. Mass movements such as large lahars and smaller seasonal debris flows can occur at volcanoes in the Cascades. A combination of seismic, infrasound, tripwires, and webcams can be used to detect and characterize these flows. A laser rangefinder can be placed on the...
Radiocarbon dating of silicified wood from around Artemisia Geyser in the Upper Geyser Basin, Yellowstone National Park Radiocarbon dating of silicified wood from around Artemisia Geyser in the Upper Geyser Basin, Yellowstone National Park
Samples of silicified wood remnants from 8 trees were collected under research permit YELL-SCI-8030 on June 17, 2023, and on September 19, 2023 adjacent to Artemisia Geyser in the Upper Geyser Basin of Yellowstone National Park. Samples were collected for radiocarbon (14C) dating of the wood to determine when the trees grew. Trees do not grow on active geyser mounds (Hurwitz and others...
Time series of seismic velocity changes around Mauna Loa from 2012 to 2024 derived from coda wave interferometry of repeating earthquakes Time series of seismic velocity changes around Mauna Loa from 2012 to 2024 derived from coda wave interferometry of repeating earthquakes
These processed data were created to investigate seismic velocity changes associated with the period of extended unrest and eruption at Mauna Loa, Island of Hawaiʻi. Primary data (i.e., seismic waveforms) are hosted at NSF SAGE Facility (https://service.iris.edu/) and were ingested by the code CWIRE Version 1.0.0 (https://doi.org/10.5066/P13BKSJJ) to produce the data analyzed in Hotovec...
REDPy Catalogs for Mauna Loa (2012-2024) REDPy Catalogs for Mauna Loa (2012-2024)
REDPy (short for Repeating Earthquake Detector in Python) is a seismic tool for automatically detecting and grouping earthquakes based on the similarity of their waveforms into "families" of related events. It can be used in near real-time for monitoring or for research. The catalogs in this release bracket the late-2022 eruption of Mauna Loa, Island of Hawaiʻi; two separate catalogs are...
