Digital Surface Model and Orthoimagery of Redoubt Volcano, Lake Clark National Park, Alaska Digital Surface Model and Orthoimagery of Redoubt Volcano, Lake Clark National Park, Alaska
Aerial photography surveys of Redoubt Volcano in Lake Clark National Park, Alaska, were conducted on August 8 and September 26, 2019, by fixed-wing aircraft to generate updated elevation data and high-quality orthoimagery. The surveys were flown by the National Park Service (NPS) Alaska Regional Office (AKRO) in partnership with the United States Geological Survey (USGS) Alaska Volcano...
NOVAC scanning DOAS spectral data and derived sulfur dioxide emission rates for Mount Cleveland, Alaska NOVAC scanning DOAS spectral data and derived sulfur dioxide emission rates for Mount Cleveland, Alaska
The Network for Observation of Volcanic and Atmospheric Change (NOVAC) is a community of volcano observatories and research institutions that together develop and apply ultraviolet differential optical absorption spectroscopy (DOAS) instruments to measure volcanic gas emission rates. The collected data are used for assessment of volcanic activity, eruption forecasting, research on...
Continuous thermal camera images of summit lava lake activity at Kīlauea volcano, Island of Hawaiʻi, 2010-2018 Continuous thermal camera images of summit lava lake activity at Kīlauea volcano, Island of Hawaiʻi, 2010-2018
The 2008-2018 eruption at the summit of Kīlauea Volcano, Island of Hawaiʻi, provided a unique opportunity to study lava lake behavior due to the accessibility and robust monitoring network (Patrick and others, 2021). During the eruption, the lava lake rose in elevation and enlarged, eventually reaching about 300 m in diameter. The lake exhibited frequent oscillations in elevation due to
Mauna Loa 2022 lava flow digital elevation models and thickness maps Mauna Loa 2022 lava flow digital elevation models and thickness maps
Mauna Loa volcano, Island of Hawaiʻi, erupted from November 27 to December 10, 2022, sending lava flows across the summit caldera (Mokuʻāweoweo) and into the upper Southwest Rift Zone, before focusing in the Northeast Rift Zone at fissure 3, sending a lava flow down the north flank that threatened a major highway. During the eruption, there was a need for updated terrain data to update...
Imagery of the Mauna Loa 2022 eruption acquired with uncrewed aircraft systems Imagery of the Mauna Loa 2022 eruption acquired with uncrewed aircraft systems
Mauna Loa volcano, Island of Hawaiʻi, erupted from November 27 to December 10, 2022, sending lava flows across the summit caldera (Mokuʻāweoweo) and into the upper Southwest Rift Zone, before focusing in the Northeast Rift Zone at fissure 3, sending a lava flow down the north flank that threatened a major highway (Zoeller and others, 2024). During the eruption, U.S. Geological Survey...
Campaign microgravity data from Yellowstone Caldera, Wyoming Campaign microgravity data from Yellowstone Caldera, Wyoming
A campaign microgravity network was established at Yellowstone Caldera, Wyoming, in 2017 as a subset of stations that were initially measured in 1977. The network has been measured subsequently on a quasi-annual basis to assess changes in gravity over time that may be related to subsurface magmatic or hydrothermal processes. This data release includes microgravity data collected by the U...
Campaign microgravity data from Lassen Volcanic Center, California Campaign microgravity data from Lassen Volcanic Center, California
A campaign microgravity network was established at Lassen Volcanic Center, California, in 2018, and a subset of that network has been measured subsequently on a quasi-annual basis to assess changes in gravity over time that may be related to subsurface magmatic or hydrothermal processes. This data release includes microgravity data collected by the U.S. Geological Survey Volcano Science...
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...
