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

Atmospheric 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

Earthquake‐Derived Seismic Velocity Changes During the 2018 Caldera Collapse of Kīlauea Volcano

, 2022
The 2018 Kīlauea caldera collapse produced extraordinary sequences of seismicity and deformation, with 62 episodic collapse events which significantly altered the landscape of the summit region.

Rapid metal pollutant deposition from the volcanic plume of Kīlauea, Hawai’i

Communications Earth & Environment, 2021
Long-lived basaltic volcanic eruptions are a globally important source of environmentally reactive, volatile metal pollutant elements such as selenium, cadmium and lead. The 2018 eruption of Kīlauea, Hawai’i produced exceptionally high discharge of metal

P Waves Emerged From Ambient Noise Cross‐Correlation Post the 2018 Kı̄lauea Eruption Revealing Middle Crust Velocity Discontinuities Beneath the Island of Hawai'i

Geophysical Research Letters, 2022
Empirical Green Functions (EGFs) obtained from ambient noise cross‐correlation are important for imaging and monitoring underground structures. The EGFs on the Island of Hawai'i in different years are similar at low frequencies (0.1–0.4 Hz), but very ...

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

Ecological 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 ...

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

Frontiers 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

Mapping pollution exposure and chemistry during an extreme air quality event (the 2018 Kīlauea eruption) using a low-cost sensor network

Proceedings of the National Academy of Sciences of the United States of America, 2021
Significance Poor air quality is a global public health issue, contributing to millions of premature deaths per year worldwide. Low-cost air quality sensors are a promising tool to improve monitoring capabilities.
