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

Geophysical 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

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

Journal 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.

Terrestrial analogs and thermal models for Martian flood lavas [PDF]

, 2000
The recent flood lavas on Mars appear to have a characteristic “platy-ridged” surface morphology different from that inferred for most terrestrial continental flood basalt flows.

Silica in a Mars analog environment: Ka'u Desert, Kilauea Volcano, Hawaii [PDF]

, 2010
Airborne Visible/Near-Infrared Imaging Spectrometer (AVIRIS) data acquired over the Ka'u Desert are atmospherically corrected to ground reflectance and used to identify the mineralogic components of relatively young basaltic materials, including 250–700 ...

Hawaiian Volcanic Ash, an Airborne Fomite for Nontuberculous Mycobacteria

GeoHealth
Nontuberculous mycobacteria (NTM) are environmentally acquired opportunistic pathogens that can cause chronic lung disease. Within the U.S., Hawai'i shows the highest prevalence rates of NTM lung infections.

Oxygen isotope geochemistry of the second HSDP core [PDF]

, 2003
Oxygen isotope ratios were measured in olivine phenocrysts (~1 mm diameter), olivine microphenocrysts (generally ~100–200 µm diameter), glass, and/or matrix from 89 samples collected from depths down to 3079.7 m in the second, and main, HSDP core (HSDP-2)

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

Geochemistry, 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 ...

Compositional boundary layers trigger liquid unmixing in a basaltic crystal mush

Nature Communications, 2019
This study seeks to tackle the question of why intermediate magmatic rock compositions are poorly represented on the Earth’s surface. The authors do so by tracking the evolution of the physical behaviour of immiscible Fe-rich liquids within a sample ...

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

Journal 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.
