Pumice cone eruptions at Aluto volcano, Ethiopia

Volcanica
Pumice cones are volcanic landforms that exist worldwide, but whose eruption has never been observed. Interpretations of these eruptions vary significantly in style, intensity, and magnitude, pertinent for volcanic hazard assessment.

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 ...

Temperature proxy data and their significance for the understanding of pyroclastic density currents

, 2008
A major dome collapse of the Soufrière Hills volcano, Montserrat, on 26 December 1997 generated a devastating pyroclastic density current that destroyed vegetation and left a distinctive tar-like deposit on the surface.

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 ...

Investigating Technology and Raw Materials Source of the Archaic and Classical Architectural Terracottas From the Athenaion in Castro (Apulia, Italy)

Archaeometry, Volume 68, Issue 3, Page 512-526, June 2026.
ABSTRACT Since 2000, archaeological excavations have brought to light the sanctuary of Athena in Castro (Apulia, Italy), including terracotta roofs dated between the 6th and 4th centuries bce. Based on their morphological and stylistic features, it is suggested that the terracotta items were manufactured in the Greek colony of Taras (modern Taranto ...

Mafic, large-volume, pyroclastic density current deposits from phreatomagmatic eruptions in the Ferrar large igneous province [PDF]

, 2005
Mafic volcaniclastic deposits are increasingly recognized as important components of continental flood basalt provinces, but the mode of origin of these deposits and the possible environmental influence of the eruptions that formed them remain poorly ...

Petrology of the 1952 Eruption and Ancient Lava and Pyroclastic Flows of Krenitsyn Peak Volcano, Onekotan Island, Kuril Arc, Russia

Geosciences
Krenitsyn Peak is one of the two active volcanoes on Onekotan Island (Greater Kuril Ridge). The inaccessibility of the island, along with the volcano being situated within a sizeable (7 km in diameter) and cold (3.7 °C) caldera lake, has led to minimal ...

Influence of the Dynamic Geological History of the Japanese Archipelago on the Molecular Phylogeography of the Riffle Beetle Zaitzeviaria ovata (Coleoptera: Elmidae)

Freshwater Biology, Volume 71, Issue 6, June 2026.
ABSTRACT The geographic genetic structure and distribution within species are shaped by factors such as dynamic tectonic activity and topographic changes associated with climate change. We used the largely flightless, freshwater‐dependent beetle Zaitzeviaria ovata (Elmidae) as a model to investigate how ancient topography and dynamic geological history

A Hidden Eruption: The 21 May 2023 Paroxysm of the Etna Volcano (Italy)

Remote Sensing
On 21 May 2023, a hidden eruption occurred at the Southeast Crater (SEC) of Etna (Italy); indeed, bad weather prevented its direct and remote observation.

Numerical simulation of explosive volcanic eruptions from the conduit flow to global atmospheric scales

Annals of Geophysics, 2005
Volcanic eruptions are unsteady multiphase phenomena, which encompass many inter-related processes across the whole range of scales from molecular and microscopic to macroscopic, synoptic and global. We provide an overview of recent advances in
