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

Geochemistry, 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.

Submarine pyroclastic flows of the 1883 eruption of Krakatau volcano

, 1991
The recent collection of samples from the seafloor surrounding Krakatau volcano provides new insights into the explosive 1883 eruption and the generation of tsunamis that claimed the lives of \u3e32 000 people.

First Direct Observations of Internal Flow Structures in a Powder Snow Avalanche: Turbulence, Instability and Particle Distribution

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Powder snow avalanches are highly dynamic, multiphase gravity‐driven flows typically composed of a dense basal layer overlain by airborne layers in which snow particles are suspended within a turbulent air phase. Despite extensive work on related systems such as pyroclastic density currents and turbidity currents, all gravity current studies ...

Emplacement of pyroclastic deposits offshore Montserrat from 3D seismic data

, 2013
During the current (1995–present) eruptive phase of the Soufrière Hills volcano on Montserrat, voluminous pyroclastic flows entered the sea off the eastern flank of the island, resulting in the deposition of well-defined submarine pyroclastic lobes ...

PYROCLASTIC FLOW DYNAMICS

, 2006
Numerical simulation of pyroclastic density currents has developed significantly in recent years and is increasingly applied to volcanological research. Results from physical modeling are commonly taken into account in volcanic hazard assessment and in the definition of hazard mitigation strategies. In this work, we modeled pyroclastic density currents

A Global, Daily Carbon Budget for Terrestrial Ecosystems Constrained by Satellite Observations of Soil Moisture: The SMAP Level 4 Carbon Product at Ten Years

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract The capacity of terrestrial ecosystems to retain carbon or sequester more atmospheric carbon is frequently investigated as a potential natural climate solution. However, global carbon inventories, national carbon assessments, and atmospheric inversion studies suffer from key limitations: infrequent estimates, low spatial resolution, or a lack ...

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

Reviews 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 ...

Submarine pyroclastic deposits formed at the Soufrière Hills volcano, Montserrat (1995–2003): What happens when pyroclastic flows enter the ocean?

, 2006
The Soufrière Hills volcano, Montserrat, West Indies, has undergone a series of dome growth and collapse events since the eruption began in 1995. Over 90% of the pyroclastic material produced has been deposited into the ocean. Sampling of these submarine

Improving the facies model for syn-eruptive fluvial successions: lessons from the Chaitén volcano and Blanco river, Chile.

Latin American Journal of Sedimentology and Basin Analysis, 2022
Typically, the stratigraphic record of syn-eruptive fluvial successions is a pyroclastic-rich one. It includes an alternation of braided channel deposits and sheet-like floodplain strata, in which the occurrence of paleosols with in situ trees and ...

Deep Origin and Shallow Launch for the Etna 122 B.C. Mafic Plinian Eruption

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Basaltic Plinian eruptions challenge our understanding of explosive volcanism. The 122 B.C. Plinian eruption of Etna ranks among the most powerful mafic explosive events known. Here, we combine volatile barometry of 122 B.C. from olivine‐hosted melt and fluid inclusions with comparative data from the sub‐Plinian Fall Stratified eruption at ...
