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

Fitting Jet Noise Similarity Spectra to Volcano Infrasound Data

open access: yesEarth and Space Science, 2021
Infrasound (low‐frequency acoustic waves) has proven useful to detect and characterize subaerial volcanic activity, but understanding the infrasonic source during sustained eruptions is still an area of active research.

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

open access: yesJournal 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 ...

Officially social: Developing a social media crisis communication strategy for USGS Volcanoes during the 2018 Kīlauea eruption

open access: yesFrontiers in Communication, 2023
The USGS Volcano Science Center has a long history of science and crisis communication about volcanoes and their eruptions. Centered mainly on websites, email notifications, traditional media, and in-person interaction in the past, our toolkit has ...

Natural Time Analysis and Nowcasting of Quasi‐Periodic Collapse Events During the 2018 Kīlauea Volcano Eruptive Sequence

open access: yesEarth and Space Science, 2022
The period of heightened volcanic and seismic activity at Kīlauea volcano on the island of Hawai’i, USA from late spring through summer 2018 included a remarkable quasi‐periodic sequence of caldera collapse events.

Unified Scaling Law for Lengths of Basaltic Lava Flows: Dependence on Erupted Volume and Effusion Rate

open access: yesGeophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Morphological scaling laws for basaltic lava flows, linking flow dimensions and eruption conditions, are essential for hazard assessment and geological analysis of basaltic eruptions. However, the governing factors influencing flow dimensions remain unclear.

Interevent Seismicity Statistics Associated With the 2018 Quasiperiodic Collapse Events at Kīlauea, HI, USA

open access: yesEarth and Space Science, 2020
Following the Mw 6.9 Hawaiian earthquake on 4 May 2018, a remarkable quasiperiodic sequence of collapse events began at Halema'uma'u Crater at the summit of Kīlauea Volcano.

Variations in Hawaiian Plume Flux Controlled by Ancient Mantle Depletion

open access: yesAGU Advances, Volume 6, Issue 2, April 2025.
Abstract Mantle plumes—upwellings of buoyant rock in Earth's mantle—feed hotspot volcanoes such as Hawai‘i. The size of volcanoes along the Hawai‘i–Emperor chain, and thus the magma flux of the Hawaiian plume, has varied over the past 85 million years. Fifteen and two million years ago, rapid bursts in magmatic production led to the emergence of large ...

The Hidden Internal Flow Dynamics of Shear‐Thinning Magma in Dikes

open access: yesAGU Advances, Volume 6, Issue 2, April 2025.
Abstract The viscosity of magma has a first‐order control on the explosivity and hazards of a volcanic eruption, and the detection of diking within the subsurface may indicate an eruption is imminent. As magma approaches the surface it is highly likely it will have a non‐Newtonian shear‐thinning rheology (apparent viscosity decreases as shear rate ...

Reconstructing Magma Storage Depths for the 2018 Kı̄lauean Eruption From Melt Inclusion CO2 Contents: The Importance of Vapor Bubbles

open access: yesGeochemistry, Geophysics, Geosystems, 2021
The 2018 lower East Rift Zone (LERZ) eruption and the accompanying collapse of the summit caldera marked the most destructive episode of activity at Kı̄lauea Volcano in the last 200 years.
