Lava fountain jet noise during the 2018 eruption of fissure 8 of Kīlauea volcano
Frontiers in Earth Science, 2022 Real-time monitoring is crucial to assess hazards and mitigate risks of sustained volcanic eruptions that last hours to months or more. Sustained eruptions have been shown to produce a low frequency (infrasonic) form of jet noise.

Ecography, Volume 2025, Issue 11, November 2025.Hawaii has experienced profound declines in native avifauna alongside the introduction of numerous bird species. While site‐specific population studies are common, landscape‐level analyses of avian population dynamics are rare, particularly in island ecosystems. To address this gap, we used a density surface model to create a spatio‐temporal projection

Crystal scavenging from mush piles recorded by melt inclusions
Nature Communications, 2019 The increasingly prevalent view of magmatic systems as mush-dominated challenges the common assumption that melt inclusions record the pre-eruptive storage and processing of the melts they were erupted with.

Seismic Evidence for a Shallow Detachment Beneath Kīlauea's South Flank During the 2018 Activity
Geophysical Research Letters, 2020 We investigate earthquake distribution and focal mechanisms associated with the 2018 Kīlauea volcano eruption in Hawaii. Our high‐precision earthquake relocations delineate an aseismic zone bounded by two subhorizontal bands of seismicity at 3.5 and 7 km

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.Abstract This study monitors the seismic velocity changes beneath the Izu‐Oshima volcano, central Japan, using ambient seismic noise records from 2003 to 2020. Applying seismic interferometry to the continuous waveform data from 24 seismic stations, we observed significant temporal variations in the seismic velocity structure.

Geophysical Research Letters, 2022 Monitoring of active volcanic systems is a challenging task due in part to the trade‐offs between collection of high‐quality data from multiple techniques and the high costs of acquiring such data.

Bulletin of Volcanology, 2020 The 2018 lower East Rift Zone eruption of Kīlauea (Hawai‘i) marked a dramatic change in the volcano’s 35-year-long rift zone eruption. The collapse of the middle East Rift Zone vent Pu‘u ‘Ō‘ō was followed by one of the volcano’s most voluminous eruptions

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.Abstract Lava tubes are subsurface conduits within a lava flow that feed its advance. Lava tube detection is important to understand lava flow dynamics and to mitigate geohazards. Here we use InSAR‐derived surface motion data, in combination with shortwave and thermal infrared imagery, to delineate a ∼14 km long lava tube system at Fernandina volcano ...

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.Abstract In their article entitled “Trapdoor Fault Activation: A Step Toward Caldera Collapse at Sierra Negra, Galapagos, Ecuador” Shreve and Delgado (2023, https://doi.org/10.1029/2023jb026437) examine co‐eruptive deformation during the 2018 eruption of Sierra Negra Volcano. One of their major conclusions is that the 2018 eruption, and specifically co‐

Distribution and Transport of Thermal Energy within Magma–Hydrothermal Systems
Geosciences, 2020 Proximity to magma bodies is generally acknowledged as providing the energy source for hot hydrothermal reservoirs. Hence, it is appropriate to think of a “magma–hydrothermal system” as an entity, rather than as separate systems.
