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

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 ...

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.

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.

Variations in Hawaiian Plume Flux Controlled by Ancient Mantle Depletion
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
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 ...

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.
