Subducting Slab Thermo‐Petrologic Structure and Intermediate‐Depth Supra‐Slab Earthquakes Beneath Southern Colombia

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract We develop 2‐D thermo‐petrologic models for two transects through southern Colombia and compare the model‐predicted temperature distributions and depths of slab dehydration with seismological observations. Along the northern transect, earthquakes occur above the relatively young subducting Nazca slab at 80–160‐km depths.

Large Particle Size and Thick Coating Influence Pyrocumulonimbus Smoke Radiative Forcing and Stratospheric Warming: Insights From the 2019–2020 Australian Megafires

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Large particle size and thick coatings have been detected in pyrocumulonimbus (pyroCb) smoke injected into the lower stratosphere, enhancing both extinction and absorption of smoke. Here, we quantified how particle size and coating, via internal mixing of non‐absorbing species on black carbon, influence pyroCb smoke radiative forcing and ...

The Fate of Iron Formations in the Deep Mantle: Constraints From Iron Oxide Reduction Kinetics Experiments

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Dense sedimentary iron formations (IFs) subducted into the mantle during Earth's early history, may have descended to the core‐mantle boundary where they could exert strong control on its thermal and seismological properties. A key unanswered question is the extent to which IFs retain their oxidized character in the much more reducing mantle ...

Attribution of Recent Change in the Stratospheric Temperature and Its Application to Future Projection

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The stratospheric temperature has continued to decline over the past half‐century, in contrast to the steady increase in the tropospheric temperature. However, the future changes in stratospheric temperature under anthropogenic influences, as well as the specific role of stratospheric interactive chemistry in their attribution and projection ...

Poromechanical and Crack Evolution of Olivine‐Rich Rock During Serpentinization

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Serpentinization alters the strength, fracture behavior, and rheology of ultramafic rocks, yet the coupled evolution of mineral reactions, cracking, and mechanical softening remains poorly constrained. We experimentally simulated serpentinization in dunite at 220°C and 15 MPa for 14 and 30 days and compared the reacted specimens with dry heat ...
