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.

Seismic Velocity Monitoring Reveals Complex Magma Transport Dynamics at Kīlauea Volcano Prior to the 2018 Eruption

open access: yesAGU Advances
Magma and pressure transport between Kīlauea's summit reservoirs and along its East Rift Zone (ERZ) are dynamic even in the absence of surface eruptions.

Elastic interaction between Mauna Loa and Kīlauea evidenced by independent component analysis

open access: yesScientific Reports, 2022
The contrasting dynamics between Mauna Loa and Kīlauea have been studied over the last 100 years from multiple viewpoints. The fact that dynamic changes of one volcano trigger a dynamic response of the other volcano indicates a connection may exist ...

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

Using phenology data to improve control of invasive plant species: A case study on Midway Atoll NWR

open access: yesEcological Solutions and Evidence, 2020
1. Restoration of degraded lands often depends on knowledge of invasive plant species’ ecology coupled with well‐timed treatments to control them. Little is known about the reproductive phenology of Verbesina encelioides (golden crownbeard), which is a ...

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

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

InSAR Time-Series Analysis With a Non-Gaussian Detector for Persistent Scatterers

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
Persistent scatterer interferometric synthetic aperture radar (PS-InSAR) is a remote sensing technique that maps patterns of crustal deformation with large spatial coverage and fine resolution.

Degassing history of water, sulfur, and carbon in submarine lavas from Kilauea volcano, Hawaii [PDF]

open access: yes, 1991
Major, minor, and dissolved volatile element concentrations were measured in tholeiitic glasses from the submarine portion (Puna Ridge) of the east rift zone of Kilauea Volcano, Hawaii.

Statistical analysis of daily seismic event rate as a precursor to volcanic eruptions [PDF]

open access: yes, 2003
We analyse time series of daily seismic event rate for the Kilauea, Hawaii, volcano between 1959 and 2000. Individual eruptions are not always preceded by an increase in event rate, and many increases in event rate do not lead to eruption.
