Variance of the Flexure Model Predictions With Rejuvenated Volcanism at Kīlauea Point, Kaua‘i, Hawai‘i

Frontiers in Earth Science, 2018
The origin of rejuvenated volcanism on mantle plume related oceanic islands remains controversial. One commonly cited model is decompressional melting related to plate flexure from the rapid loading of the lithosphere by the formation of a shield volcano

Measuring SO2 Emission Rates at Kīlauea Volcano, Hawaii, Using an Array of Upward-Looking UV Spectrometers, 2014–2017

Frontiers in Earth Science, 2018
Retrieving accurate volcanic sulfur dioxide (SO2) gas emission rates is important for a variety of purposes. It is an indicator of shallow subsurface magma, and thus may signal impending eruption or unrest.

Characterization of the isotopic composition and bulk ion deposition of precipitation from Central to West Hawaiʻi Island between 2017 and 2019

Journal of Hydrology: Regional Studies, 2021
Study region: The current study evaluates the isotopic and chemical compositions of rainfall from central to leeward Hawaiʻi Island, an area characterized by the interactions of Pacific trade wind flow with two 4,000-meter high mountains as well as one ...

Ozone Depletion in Tropospheric Volcanic Plumes: From Halogen-Poor to Halogen-Rich Emissions

Geosciences, 2018
Volcanic halogen emissions to the troposphere undergo a rapid plume chemistry that destroys ozone. Quantifying the impact of volcanic halogens on tropospheric ozone is challenging, only a few observations exist.

Dynamics of the December 2020 Ash‐Poor Plume Formed by Lava‐Water Interaction at the Summit of Kīlauea Volcano, Hawaiʻi

Geochemistry, Geophysics, Geosystems, 2023
On 20 December 2020, after more than 2 years of quiescence at Kīlauea Volcano, Hawaiʻi, renewed volcanic activity in the summit crater caused boiling of the water lake over a period of ∼90 min. The resulting water‐rich, electrified plume rose to 11–13 km

Insights on the state of stress in the mantle beneath Pahala, Hawai‘i

Volcanica
Magma supply rates from the mantle to Hawaiian volcanoes serve as an important control on eruptive behavior at the surface. The Pa ̄hala Sill Complex, a collection of magma-bearing, seismogenic structures at 40 km depth beneath Hawai‘i, presents an ...

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

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.
