Using paleomagnetism to determine the heating effect of lava flows on underlying substrates
Volcanica, 2022 The extent to which heat from lava flows passes into underlying and adjacent materials has significant implications for volcanic hazard studies. Here we demonstrate how paleomagnetism can be used as a tool to determine the heating effects of lava flows ...

Evolution of dike opening during the March 2011 Kamoamoa fissure eruption, Kīlauea Volcano, Hawai`i [PDF]
Journal of Geophysical Research: Solid Earth, 2013 AbstractThe 5–9 March 2011 Kamoamoa fissure eruption along the east rift zone of Kīlauea Volcano, Hawai`i, followed months of pronounced inflation at Kīlauea summit. We examine dike opening during and after the eruption using a comprehensive interferometric synthetic aperture radar (InSAR) data set in combination with continuous GPS data.

Submarine lava deltas of the 2018 eruption of Kīlauea volcano [PDF]
, 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 ...

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

Oxygen Isotope Evidence for Chemical Interaction of Ki lauea Historical Magmas with Basement Rocks [PDF]
Journal of Petrology, 2007 Kīlauea historical summit lavas have a wide range in matrix δ^(18)_OVSMOW values (4·9–5·6‰) with lower values in rocks erupted following a major summit collapse or eruptive hiatus. In contrast, δ^(18)O values for olivines in most of these lavas are nearly constant (5·1 ± 0·1‰).

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

Relative seismic velocity variations correlate with deformation at Kīlauea volcano. [PDF]
Sci Adv, 2017 Seismic noise interferometry allows the continuous and real-time measurement of relative seismic velocity through a volcanic edifice. Because seismic velocity is sensitive to the pressurization state of the system, this method is an exciting new ...

Volcano-tectonic interactions as triggers of volcanic eruptions [PDF]
, 2013 Surface displacements and edifice deformations at active volcanoes can occur when magma reservoirs begin to inflate as new magma enters them. Volcanoes are also subjected to a variety of external lithospheric stresses that are thought to be responsible ...

Efficacy of detection canines for avian botulism surveillance and mitigation
Conservation 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).
