Time‐dependent (Creep) Compaction in Volcanic Rocks

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Porous volcanic rocks form volcanic edifices and host key geothermal reservoirs worldwide. When subjected to constant stress above dilatancy in the brittle regime, these materials undergo time‐dependent failure known as brittle creep. In the ductile regime, where deformation is compactive, time‐dependent compaction—compaction creep—has been ...

Scales of recent submarine volcanism

, 1982
Submarine volcanic activity is confined to (1) rift zones of mid-ocean ridges (MOR) and transform faults, (2) hot spots (HS) and belts of hot spots («hot lines »), (3) systems of island arcs (IA) and (4) marginal seas (MS). Volcanic activity may occur on the oceanic flanks of deep sea trenches and marginal swells between trenches and the ocean floor ...

Global Evidence for Off‐Axis Flexural Modification of Abyssal Hill Faults at Mid‐Ocean Ridges

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Young oceanic lithosphere flexes as axial topography decays across mid‐ocean ridge shoulders, yet this deformation has been quantified at only a few segments, leaving its global expression poorly constrained. We analyzed 50 across‐axis bathymetric profiles from 21 regions spanning slow to fast spreading rates, identified 1,201 abyssal‐hill ...

Large (∼80 km) Shield Volcanoes on the Moon Possibly Fed by Shallow Magma Reservoirs

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Large shield volcanoes are among the most prominent volcanic structures on terrestrial bodies. The Moon, while volcanically very active in the past and hosting various volcanic features, seems to lack such large shield volcanoes. Here, we report the identification of two lunar volcanic domes (Prinz‐Harbinger and Theophilus) with diameters ...

Coal Mining as a Driver of Land Use and Land Cover Change and Degradation: A Case in Moatize City, Mozambique

Land Degradation &Development, Volume 37, Issue 13, Page 9126-9143, 15 August 2026.
ABSTRACT Coal remains a major global energy source despite ongoing environmental controversies, particularly, regarding climate change and landscape transformation. This study investigates the spatiotemporal dynamics of land use and land cover (LULC) in the Moatize Coal Basin (MCB), Mozambique, between 1990 and 2024, with a specific focus on land ...

Complex Iridium Oxides Converge In Structure And Reactivity During Acidic Oxygen Evolution Electrocatalysis

Advanced Energy Materials, Volume 16, Issue 29, 5 August 2026.
Ir‐based double perovskites restructure during acidic oxygen evolution electrocatalysis through dissolution of non‐Ir cations and convergence toward IrOx active‐site motifs with similar structure and intrinsic activity across compositions. The identity of the dissolving cations controls dissolution and surface reconstruction kinetics, clarifying how ...

Early Cretaceous intraplate seamounts from Guanajuato, central Mexico: geochemical and mineralogical data

Revista Mexicana de Ciencias Geológicas, 2018
An Early Cretaceous submarine volcanic and volcaniclastic sequence is found in the north- western part of the Sierra de Guanajuato, in central Mexico. This sequence is formed by mildly alkaline basaltic pillow lavas interbedded with massive lava flows ...

Submarine volcanic activity: Detection, monitoring, and interpretation

Eos, Transactions American Geophysical Union, 1989
Volcanic edifices on the ocean floor are much more numerous than suggested by available bathymetric charts [Batiza, 1982; Jordan et al., 1983]. More recently, Smith and Jordan [1987] have proposed an exponential model for the distribution of seamounts based on their dimensions.

Tunable Lattice Coordination in W‐Based Double Perovskites via Correlated Ca/Co Doping for Efficient Oxygen Evolution Catalysis

ChemCatChem, Volume 18, Issue 15, 14 August 2026.
Precise B‐site cation engineering in tungsten‐based double perovskites unlocks a highly reversible oxygen evolution reaction (OER) pathway. The optimized electrocatalyst shows robust intrinsic kinetics and operational longevity. Analysis reveals that a dynamic Co–O–W coordination network is a synergetic active structure, stabilizing active centers and ...
