Overflight structure-from-motion digital elevation model and orthophotos of Shishaldin Volcano, Alaska, 2024 Overflight structure-from-motion digital elevation model and orthophotos of Shishaldin Volcano, Alaska, 2024
The Alaska Volcano Observatory conducted overflights of Shishaldin Volcano, Alaska, in July–August 2024 to characterize the morphological changes to the summit area following the 2023 and 2019–2020 eruptions. Oblique airphotos were taken during helicopter overflights on July 30 and August 1. The photos were processed with structure-from-motion (SfM) photogrammetric methods to derive a...
Campaign microgravity data from Mount Hood, Oregon Campaign microgravity data from Mount Hood, Oregon
A campaign microgravity network was established between Vancouver, Washington, and Mount Hood, Oregon, in 2021 and has been measured at least annually, and sometimes more often, in subsequent years. The purpose of the network is to assess changes in gravimeter calibration, as well as to monitor potential gravity changes related to subsurface magmatic or hydrothermal processes at Mount...
Post-2018-collapse microgravity data from campaign measurements at Kīlauea, Hawaiʻi Post-2018-collapse microgravity data from campaign measurements at Kīlauea, Hawaiʻi
Campaign microgravity data have been collected at Kīlauea, Hawaiʻi, since 1975 to assess changes in mass associated with magmatic activity. The network of stations was disrupted by the 2018 summit collapse and was subsequently reestablished, with surviving and some new sites occupied regularly to track magmatic activity beneath the volcano. This data release includes microgravity data...
Tephra accumulation and wind data for Kīlauea’s 2008–2018 lava lake eruption Tephra accumulation and wind data for Kīlauea’s 2008–2018 lava lake eruption
The 2008–2018 summit eruption at Kīlauea formed an active and slowily expanding lava lake within Halemaʻumaʻu Crater that lasted 10 years before draining. To consistently collect proximal tephra ejected from the lava lake, which was nested within the new, informally named “Overlook crater,” a network of ten plastic buckets was established early and emptied on most days of the eruption...
Tiltmeter data on the Island of Hawaiʻi collected by the Hawaiian Volcano Observatory from July 1, 2025 to present with 60-day latency (Updated 2026-04-02) Tiltmeter data on the Island of Hawaiʻi collected by the Hawaiian Volcano Observatory from July 1, 2025 to present with 60-day latency (Updated 2026-04-02)
Tiltmeter data on the Island of Hawaiʻi collected by the Hawaiian Volcano Observatory from July 1, 2025 to present with 60-day latency. These data are collected by the USGS Hawaiian Volcano Observatory. This dataset will be updated as new tiltmeter data are collected and approved with 60-day latency.
40Ar/39Ar geochronologic data for ignimbrites of the Sour Creek dome, Yellowstone Volcano 40Ar/39Ar geochronologic data for ignimbrites of the Sour Creek dome, Yellowstone Volcano
40Ar/39Ar data presented in this data release are from the Sour Creek dome, one of two resurgent domes in Yellowstone caldera, WY. These data were collected to determine the age of volcanic rocks that make up Sour Creek dome, and to determine if the Sour Creek dome is indeed a resurgent dome or instead formed by another means. Specifically, these data were collected to test if volcanic...
Whole-rock chemistry and radiocarbon ages for tephras and lavas used to establish the eruption history over the past 15 kyr at Laguna del Maule volcanic field along the Chilean-Argentine border Whole-rock chemistry and radiocarbon ages for tephras and lavas used to establish the eruption history over the past 15 kyr at Laguna del Maule volcanic field along the Chilean-Argentine border
The Laguna del Maule (LdM) volcanic field as mapped by Hildreth and others (2010) includes 36 postglacial rhyolite and rhyodacite coulees and domes that erupted from 24 separate vents that encircle the 54-km2 lake basin. Although recognizing that such effusive events commonly have accompanying explosive phases, pursuing downwind tephra studies into Argentina was not done then and the...
Data used to determine water volumes and solute discharge from geyser eruptions in the Upper Geyser Basin, Yellowstone National Park, USA Data used to determine water volumes and solute discharge from geyser eruptions in the Upper Geyser Basin, Yellowstone National Park, USA
There are approximately 500 active geysers in Yellowstone National Park, USA, and the geysers in Upper Geyser Basin are some of the most iconic in the world. Between April 11 and 15, 2025, we attempted to quantify the volume of water erupting from several geysers in Upper Geyser Basin including Old Faithful, Beehive, Lion, Castle, Grand, Grotto and Riverside Geysers using a combination...
Sample details and compositional data collected during episodes 1–39 (2024-2025) of the 2024-ongoing episodic Halema‘uma‘u eruption of Kīlauea, Island of Hawaiʻi Sample details and compositional data collected during episodes 1–39 (2024-2025) of the 2024-ongoing episodic Halema‘uma‘u eruption of Kīlauea, Island of Hawaiʻi
Samples for episodes 1–39 (2024-2025) of the 2024-ongoing episodic Halema‘uma‘u Kīlauea eruption were collected by the U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO) field teams from within publicly closed areas 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-XRF...
Ultraviolet remote sensing data from a spectrometer fenceline array (DFence) installed at Kīlauea for measuring volcanic gas emissions Ultraviolet remote sensing data from a spectrometer fenceline array (DFence) installed at Kīlauea for measuring volcanic gas emissions
In 2012, the U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO) installed an array of zenith-pointing ultraviolet spectrometers to track gas emissions from summit of Kīlauea (Businger et al., 2015; Elias et al., 2018). The instruments are arranged in an arc perpendicular to the dominant trade-wind direction approximately 2 kilometers (km) southwest of the actively degassing...

This dataset includes major-, minor-, and trace-element analyses by electron probe microanalysis (EPMA) and trace-element analyses by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) of olivine, plagioclase, clinopyroxene, and orthopyroxene minerals from scoria and lava samples from the Kamakaiʻa Hills of the Southwest Rift Zone of Kīlauea volcano, Island of...
Image and video catalog of the 2018 summit collapse and lower East Rift Zone eruption of Kīlauea volcano, Island of Hawaiʻi, Hawaii Image and video catalog of the 2018 summit collapse and lower East Rift Zone eruption of Kīlauea volcano, Island of Hawaiʻi, Hawaii
This data release contains an image and video catalog of the 2018 summit collapse and lower East Rift Zone eruption of Kīlauea volcano, on the Island of Hawaiʻi. An intrusion of magma into Kīlauea’s lower East Rift Zone resulted in a four-month-long eruption from May 3 to September 5, 2018 (Neal and others, 2018). The eruption produced lava flows that covered an area of 35.5 square...
