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.

Geophysical Research Letters, 2021 Long‐period (LP), hybrid, and volcano‐tectonic (VT) seismicity are important indicators for tracking the evolution of volcanic processes. Here, we propose an unsupervised learning method to classify 5,949 seismic events in Kilauea volcano, Hawai'i ...

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.

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.

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
