Catastrophic lava flow levee failure: precursors, processes, and implications

open access: yesVolcanica
During an effusive eruption crisis the initial advance of a lava flow is typically the primary focus of model forecasts and hazard management efforts. Flow branching and lateral expansion of lava flows can pose significant dangers within evolving flow ...

Social sensing the 2018 Kīlauea Volcanic eruption through community Facebook use

open access: yesVolcanica
There is a lack of understanding around the impacts and responses of communities receiving hazard and risk information during volcanic crises, but social media posts may be able to provide valuable insights.

In-situ monitoring of 3He/4He in summit gases of Kilauea Volcano (Hawaii) prior to the 2020 eruption

open access: yesJournal of Applied Volcanology, 2023
We present He isotope (3He/4He) data from a fumarole and near-ground gases measured in-situ at the Sulfur Banks solfatara field at the summit of Kilauea Volcano, Hawaii.

Topographic Changes During the 2018 Kīlauea Eruption From Single‐Pass Airborne InSAR

open access: yesGeophysical Research Letters, 2019
The 2018 eruption of Kīlauea volcano, Hawai‘i, was its most effusive in over 200 years. We apply the airborne Glacier and Ice Surface Topography Interferometer (GLISTIN‐A) interferometric synthetic aperture radar (InSAR) instrument to measure topographic

Complex styles of phreatomagmatic explosions at Kīlauea Volcano, Hawaii, controlled by magma structure

open access: yesFrontiers in Earth Science, 2023
Explosive eruptions at basaltic volcanoes remain poorly understood. Kīlauea Volcano is a type locality for basaltic eruptions and is well-known for effusive activity.

Phosphate Scavenging During Lava‐Seawater Interaction Offshore of Kīlauea Volcano, Hawaii

open access: yesGeochemistry, Geophysics, Geosystems, 2021
The 2018, subaerial eruption of Kīlauea volcano, Hawaii, resulted in a 5‐km‐long stretch of coastline that actively drained lava into the ocean. Nutrients were added to the surrounding ocean through the dissolution of basaltic rock and thermal upwelling ...

Erupções do Kilauea e o arquipélago havaiano: a geologia da tectônica de placas e dos pontos quentes

open access: yesJournal of Big History, 2019
A four-month surge of Mount Kilauea eruptions (May to August 2018) on the Big Island reminds us that the whole chain of Hawaiian islands has been built by volcanic activity.

Learning Wave Scattering Properties From Seismograms

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Heterogeneities in the Earth's crust scatter seismic waves at many scales, trapping seismic energy and producing coda waves that encode valuable information on geological structures. In regions such as volcanoes and fault systems, analyzing coda waves is essential for characterizing non‐uniform subsurface heterogeneity, improving ...

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.
