Seismic Velocity Monitoring Reveals Complex Magma Transport Dynamics at Kīlauea Volcano Prior to the 2018 Eruption

open access: yesAGU Advances, Volume 6, Issue 6, December 2025.
Abstract Magma and pressure transport between Kīlauea's summit reservoirs and along its East Rift Zone (ERZ) are dynamic even in the absence of surface eruptions. However, these processes do not always produce surface manifestations and may sometimes elude detection by current geological and geodetic monitoring.

Hawaiʻi residents' perceptions of Kīlauea's 2018 eruption information

open access: yesVolcanica, 2023
The 2018 eruption of Kīlauea Volcano was notable for its variety of large and spatially distinct hazards, simultaneously affecting three geographically disparate, culturally diverse regions in Hawaiʻi.

A History of UNAVCO: Four Decades of Advancing Geodesy

open access: yesPerspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract UNAVCO was a university‐governed consortium funded by the National Science Foundation (NSF), with support from the National Aeronautics and Space Administration (NASA) and the United States Geological Survey (USGS), to support geoscience research and education using geodesy.

No Measurable Calcium Isotopic Fractionation During Crystallization of Kilauea Iki Lava Lake

open access: yesGeochemistry, Geophysics, Geosystems, 2018
In order to investigate possible Ca isotopic fractionation during basaltic magma differentiation, we measured Ca isotopic compositions of lavas recovered from Kilauea Iki lava lake at Hawaii.

Carbon Dioxide Emissions During the 2018 Kilauea Volcano Eruption Estimated Using OCO‐2 Satellite Retrievals

open access: yesGeophysical Research Letters, 2020
This study applies Orbiting Carbon Observatory‐2 (OCO‐2) column‐averaged dry‐air mole fractions of CO2 (XCO2) to constrain CO2 fluxes during the 2018 Kilauea volcano eruption.

Resolution and Error Constraints of Topographic Measurements for Accurate Lava Flow Forecasting

open access: yesGeophysical Research Letters, Volume 52, Issue 21, 16 November 2025.
Abstract The main parameters required to forecast lava flows are the eruption effusion rate, the lava viscosity, and the pre‐eruption topography. We focus on how the spatiotemporal resolution and vertical errors of topographic measurements affect lava flow forecasts.

Lava fountain jet noise during the 2018 eruption of fissure 8 of Kīlauea volcano

open access: yesFrontiers in Earth Science, 2022
Real-time monitoring is crucial to assess hazards and mitigate risks of sustained volcanic eruptions that last hours to months or more. Sustained eruptions have been shown to produce a low frequency (infrasonic) form of jet noise.

Quantifying landscape‐level biodiversity change in an island ecosystem: a 50‐year assessment of shifts in the Hawaiian avian community

open access: yesEcography, Volume 2025, Issue 11, November 2025.
Hawaii has experienced profound declines in native avifauna alongside the introduction of numerous bird species. While site‐specific population studies are common, landscape‐level analyses of avian population dynamics are rare, particularly in island ecosystems. To address this gap, we used a density surface model to create a spatio‐temporal projection

Recent activity at Nyiragongo and lava-like occurrences [PDF]

open access: yesBulletin of the Geological Society of Finland, 1985
The behaviour of Nyiragongo, before and after its outbreak on January 10th, 1977, as compared with the behaviour of the other two volcanoes containing subpermanent lava-lakes nowadays, Erta'Ale and Mount Erebus, suggests that the considerable convection ...
