Experimental aqueous fluidization of ignimbrite

open access: yes, 2001
International audienceExperiments were carried out on the aqueous¯uidization behaviour of ignimbrite and the associated formation of¯uidescape pipes. The starting material was an ignimbrite that had been saturated with water under vacuum until 80^15% of ...

Rift Development, Tectonic Forcings, and Magmatic Feedbacks at Santorini and Kolumbo Volcanoes Constrained by Scientific Drilling and Core‐Seismic Integration

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Volcanism in continental rifts, rifted volcanic arcs, and back‐arc basins is fundamentally coupled with crustal extension. However, the precise geometry and timing of the fault systems that facilitate magma transport and accommodate extension remain poorly constrained.

Eruption Source Parameters in Volcanic Plume Modeling: Advances, Challenges, and Future Directions

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Accurately predicting the atmospheric dispersion of volcanic ash and gases is crucial for both scientific understanding and hazard mitigation. Estimating Eruption Source Parameters (ESP), such as mass eruption rate, plume height, duration, and particle size distribution and properties, remains challenging due to the complex nature of volcanic ...

Arc Heat Flow and Magmatic Heat Budgets

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract We evaluate hydrothermal heat loss from 11 volcanic‐arc segments (∼6,000 km of arc length, ∼10% of the global total), motivated by the observation that much magmatic heat ultimately crosses the land surface as heated aqueous fluid. Heat loss takes place by volcanic eruption, geothermal heat conduction to the surface, fumarolic (vapor ...

What can lithics tell us about hominin technology's ‘primordial soup’? An origin of stone knapping via the emulation of Mother Nature

open access: yesArchaeometry, Volume 68, Issue S3, Page S8-S30, June 2026.
Abstract The use of stone hammers to produce sharp stone flakes—knapping—is thought to represent a significant stage in hominin technological evolution because it facilitated the exploitation of novel resources, including meat obtained from medium‐to‐large‐sized vertebrates. The invention of knapping may have occurred via an additive (i.e., cumulative)

Lithostratigraphic analysis and geochemistry of a vitric spatter-bearing ignimbrite: the Quaternary Adeje Formation, Cañadas volcano, Tenerife [PDF]

open access: yes, 2013
"The 1.5-Ma Adeje Formation in SW Tenerife contains an ignimbrite sheet with remarkable textural and chemical complexity. A basal Plinian pumice-fall layer is overlain by a partly welded compound ignimbrite in which phonolitic pumice lapilli and dense ...

Plant species richness response to atmospheric nitrogen deposition across bedrock types in the United States and Czechia

open access: yesEcosphere, Volume 17, Issue 5, May 2026.
Abstract Atmospheric nitrogen (N) deposition leads to many changes in terrestrial and aquatic ecosystems, affecting ecosystem processes and species composition. Terrestrial vegetation often shifts from being N‐limited to light‐limited and becomes dominated by a few fast‐growing strong competitors and generalist species.

Determining magmatic volatile contributions to the Campanian Ignimbrite, Italy

open access: yes, 2021
The trachytic Campanian Ignimbrite was emplaced at 39.8 ka near Naples, Italy, in the largest European eruption of the past 200 ka. Many factors, including the far-reaching extent of deposits, with co-ignimbrite fallout found as far away as Russia ...

Integrated VES–ERI–MASW‐Geotechnical Investigation for Building Foundation Site Suitability at the Proposed Wachemo University Referral Hospital, Hosanna, Central Ethiopia

open access: yesEngineering Reports, Volume 8, Issue 5, May 2026.
Integrated VES, ERI, and MASW surveys, constrained by boreholes, delineate a central low‐resistivity/low‐V s weak corridor and more competent volcanic strata at depth. The eastern sector offers preferable foundation conditions, while identified weak zones require ground improvement or deep foundations to mitigate differential‐settlement risk.
