Magma Pressure-Temperature-Time Paths During Mafic Explosive Eruptions
Frontiers in Earth Science, 2020 We have constrained syneruptive pressure-temperature-time (P-T-t) paths of mafic magmas using a combination of short-timescale cooling and decompression chronometers. Recent work has shown that the thermal histories of crystals in the last few seconds to

Comprehensive High‐Precision Relocation of Seismicity on the Island of Hawai‘i 1986–2018
Earth and Space Science, 2021 Abundant seismicity beneath the Island of Hawai‘i from mantle depths to the surface plays a central role in understanding how volcanoes work, grow, and evolve at this intraplate oceanic hotspot.

Post‐2018 Caldera Collapse Re‐Inflation Uniquely Constrains Kīlauea's Magmatic System
Journal of Geophysical Research: Solid Earth, 2021 From August 2018 to May 2019, Kīlauea’s summit exhibited unique, simultaneous, inflation and deflation, apparent in both GPS time series and cumulative InSAR displacement maps.

Vog: Using Volcanic Eruptions to Estimate the Health Costs of Particulates
The Economic Journal, EarlyView., 2018 The negative consequences of long‐term exposure to particulate pollution are well established but a number of studies find no effect of short‐term exposure on health outcomes. The high correlation of industrial pollutants complicates the estimation of the impact of individual pollutants on health.

Submarine lava deltas of the 2018 eruption of Kīlauea volcano
Bulletin of Volcanology, 2021 Hawaiian and other ocean island lava flows that reach the coastline can deposit significant volumes of lava in submarine deltas. The catastrophic collapse of these deltas represents one of the most significant, but least predictable, volcanic hazards at ...

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

Communications Earth & Environment, 2020 Volcanoes represent one of the largest natural sources of metals to the Earth’s surface. Emissions of these metals can have important impacts on the biosphere as pollutants or nutrients.

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.

Chalcophile elements track the fate of sulfur at Kīlauea Volcano, Hawai’i
Geochimica et Cosmochimica Acta, 2020 Chalcophile element concentrations in melt inclusions and matrix glasses may be used to investigate low pressure degassing processes, as well as sulfide saturation during crustal fractionation, and mantle melting.
