Trends in Ocean S‐Isotopes May Be Influenced by Major LIP Events

open access: yesGeophysical Monograph Series, Page 341-376., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

A discontinuous Galerkin finite-element model for fast channelized lava flows v1.0 [PDF]

open access: yesGeoscientific Model Development, 2021
Lava flows present a significant natural hazard to communities around volcanoes and are typically slow-moving (<1 to 5 cm s−1) and laminar. Recent lava flows during the 2018 eruption of Kīlauea volcano, Hawai'i, however, reached speeds as high as 11 ...

Estimating the volcanic emission rate and atmospheric lifetime of SO2 from space: a case study for Kīlauea volcano, Hawai`i [PDF]

open access: yesAtmospheric Chemistry and Physics, 2014
We present an analysis of SO2 column densities derived from GOME-2 satellite measurements for the Kīlauea volcano (Hawai`i) for 2007–2012. During a period of enhanced degassing activity in March–November 2008, monthly mean SO2 emission rates and

Composition and spectroscopy of olivine xenocrysts from the Hawaiian tholeiitic basalts

open access: yesУчёные записки Казанского университета: Серия Естественные науки, 2020
Tholeiitic basalts of the Hawaiian Mauna Loa and Kīlauea volcanoes (USA) contain olivine xenocrysts with chromespinelide inclusions. Their chemical composition and spectroscopic properties were investigated and compared with olivine of another ...

Efficacy of detection canines for avian botulism surveillance and mitigation

open access: yesConservation Science and Practice, 2021
Hawai'i's endangered waterbirds have experienced epizootics caused by ingestion of prey that accumulated a botulinum neurotoxin produced by the anaerobic bacterium Clostridium botulinum (avian botulism; Type C).

A new permanent, low-cost, low-power SO2 camera for continuous measurement of volcanic emissions

open access: yesFrontiers in Earth Science, 2023
Since its introduction to volcanology in the mid-2000 s, the SO2 camera has become an important instrument for the acquisition of accurate and high time-resolution SO2 emission rates, aiding in hazard assessment and volcanological research. However, with

Reply to Comment by Wei and Shen on “Seismic Velocity Variations at Different Depths Reveal the Dynamic Evolution Associated With the 2018 Kilauea Eruption”

open access: yesGeophysical Research Letters, 2023
We would like to thank Wei and Shen (2023, https://doi.org/10.1029/2022GL102596) (W23) for their comments on our recent article on GRL. In their comments, Wei and Shen argued that tremor signal on the right side of the cross‐correlation function (CCF) of

Magma Pressure-Temperature-Time Paths During Mafic Explosive Eruptions

open access: yesFrontiers 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

open access: yesEarth 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.
