Fossil trees, tree moulds and tree casts in the Palaeocene Mull Lava Field, NW Scotland: context, formation and implications for lava emplacement [PDF]

, 2016
Megafossils and macrofossils of terrestrial plants (trees, leaves, fruiting bodies, etc.) are found in sedimentary and pyroclastic units interbedded with lavas in many ancient lava fields worldwide, attesting to subaerial environments of eruption and the

Shear-Wave Velocity Characterization of the USGS Hawaiian Strong-Motion Network on the Island of Hawaii and Development of an NEHRP Site-Class Map [PDF]

, 2011
To assess the level and nature of ground shaking in Hawaii for the purposes of earthquake hazard mitigation and seismic design, empirical ground-motion prediction models are desired.

Extensive, water-rich magma reservoir beneath southern Montserrat [PDF]

, 2011
South Soufriere Hills and Soufriere Hills volcanoes are two km apart at the southern end of the island of Montserrat, West Indies. Their magmas are distinct geochemically, despite these volcanoes having been active contemporaneously at 131-129 ka. We use

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 ...

Forecasting SO2 emission of Kilauea volcano using intelligent method of data analysis

Sistemnì Doslìdženâ ta Informacìjnì Tehnologìï, 2019
Kilauea is one of the most active and well-known volcanoes in the world and most of our knowledge of volcanism originates from its research. During a long study of volcanoes, many different methods of forecasting their activity were proposed, from the ...

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

Satellite detection, long-range transport, and air quality impacts of volcanic sulfur dioxide from the 2014–2015 flood lava eruption at Bárðarbunga (Iceland) [PDF]

, 2015
The 2014–2015 Bárðarbunga-Veiðivötn fissure eruption at Holuhraun produced about 1.5 km3 of lava, making it the largest eruption in Iceland in more than 200 years.

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.
