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.

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract The study of terrestrial lava tubes is essential for understanding geological processes occurring during volcanic activity on other planetary bodies, such as Mars. These processes lead to the formation of minerals analogous to those found on other planets.

Recent activity at Nyiragongo and lava-like occurrences [PDF]
Bulletin of the Geological Society of Finland, 1985 The behaviour of Nyiragongo, before and after its outbreak on January 10th, 1977, as compared with the behaviour of the other two volcanoes containing subpermanent lava-lakes nowadays, Erta'Ale and Mount Erebus, suggests that the considerable convection ...

Learning Wave Scattering Properties From Seismograms
Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.Abstract Heterogeneities in the Earth's crust scatter seismic waves at many scales, trapping seismic energy and producing coda waves that encode valuable information on geological structures. In regions such as volcanoes and fault systems, analyzing coda waves is essential for characterizing non‐uniform subsurface heterogeneity, improving ...

Agricultural and Forest Entomology, Volume 28, Issue 1, Page 49-60, February 2026.Abstract Wood boring ambrosia beetles play a central role in the spread of Ceratocystis wilt of ‘ōhi‘a, a fungal disease caused by Ceratocystis lukuohia that kills the bioculturally important ‘ōhiʻa (Metrosideros polymorpha) tree. Beetles contribute to the spread of the disease by extruding fungus‐infected wood particles (frass). Disease mitigation can

Social sensing a volcanic eruption: application to Kīlauea, 2018 [PDF]
Natural Hazards and Earth System SciencesProtecting lives and livelihoods during volcanic eruptions is the key challenge in volcanology, conducted primarily by volcano monitoring and emergency management organisations, but it is complicated by scarce knowledge of how communities respond in ...

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract Observations of ground deformation provide insights on the triggering mechanisms of eruptions. At Aniakchak Crater (Aleutians) InSAR measured ∼ ${\sim} $72 cm of uplift in less than 7 months between 2022 and 2023. The uplift can be explained by the inflation of a point pressure source at a depth of 3.2 km.

The Age and Composition of the Voyager Seamounts: Evidence for a Long‐Lived Marquesas Mantle Source
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.Abstract We present new observations on the dynamics and locations of deep mantle reservoirs derived from the ages and compositions of Voyager Seamount Chain lava flows. The previously unexplored Voyager Seamount Chain trends NW–SE between the Mid‐Pacific Mountains and the Northwestern Hawaiian Ridge.
