Microstructural constraints on magmatic mushes under Kīlauea Volcano, Hawaiʻi

Nature Communications, 2020
Olivine crystals with prominent intracrystalline distortions have previously been used to quantify deformational processes within the mantle. Here, the authors show that similar techniques can be applied to deformed volcanic olivine crystals, providing ...

Composition and spectroscopy of olivine xenocrysts from the Hawaiian tholeiitic basalts

Учёные записки Казанского университета: Серия Естественные науки, 2020
Tholeiitic basalts of the Hawaiian Mauna Loa and Kīlauea volcanoes (USA) contain olivine xenocrysts with chromespinelide inclusions. Their chemical composition and spectroscopic properties were investigated and compared with olivine of another ...

Exploring Terrestrial Lava Tubes as Martian Analogs (I): Multi‐Analytical Study of Mineralization Processes in Cueva del Vidrio, La Palma (Canary Islands)

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.

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.

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 ...

Temporal associations between ambrosia beetles and ʻōhiʻa (Metrosideros polymorpha) artificially inoculated with Ceratocystis lukuohia

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

Abnormally Large Magma Flux Does Not Lead to Eruption in Subduction Zone Calderas: The 2022–2023 Episode of Uplift of Aniakchak Crater (Aleutians)

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 cascading origin of the 2018 Kīlauea eruption and implications for future forecasting

Nature Communications, 2020
The 2018 summit and flank eruption of Kīlauea Volcano was one of the largest volcanic events in Hawaiʻi in 200 years. Data suggest that a backup in the magma plumbing system at the long-lived Puʻu ʻŌʻō eruption site caused widespread pressurization in ...

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.

Detecting pre-eruptive magmatic processes of the 2018 eruption at Kilauea, Hawaii volcano with ambient noise interferometry

Earth, Planets and Space, 2020
A sequence of eruptions in the lower East Rift Zone (LERZ) of the Kilauea, Hawaii volcano commenced in early May 2018 and caused serious damage and residential evacuation.
