From Magma to Atmosphere: Halogen Fluxes During Volcanic Eruptions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Volcanic eruptions release significant quantities of volatile elements into the atmosphere and stratosphere. Plinian eruptions are particularly efficient at dispersing these elements due to their large magma volumes and high eruption columns.

Calcium Solubility of Bridgmanite in Subducted Basalt in Earth's Lower Mantle

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The calcium solubility in bridgmanite and the resulting abundance of davemaoite under lower‐mantle pressure‐temperature conditions have been under debate following a recent report of extensive calcium dissolution in bridgmanite. We experimentally investigated the calcium solubility in bridgmanite in a basaltic composition at pressures up to ...

Back‐Propagating Earthquake Rupture Controlled by Fluid‐Modulated Effective Normal Stress

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Back‐propagating earthquake rupture (BPR), where slip migrates opposite to the main rupture direction, is observed in several earthquakes but its origin remains poorly understood, particularly the role of fluids. We use dynamic simulations of frictional sliding coupled with fluids to explore the mechanisms of BPR. Our simulations show that BPR

Transient Creep on the Yarlung Zangbo Suture in Southern Tibet Triggered by the 2015 Gorkha (Nepal) Earthquake

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Large earthquakes often elevate seismicity in surrounding regions, as seen on the Xainza‐Dinggyê rift in southern Tibet after the 2015 MW 7.8 Gorkha (Nepal) earthquake. In contrast, the EW‐trending Yarlung Zangbo suture (YZS), located directly north of this event, exhibits seismic quiescence.

The Significance of Inherited Crustal Thickening in Surface Uplift of Hangai Dome in Central Mongolia

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract The Hangai Dome in central Mongolia represents one of the most prominent intracontinental uplifts, yet the relative contributions of crustal and mantle dynamics in sustaining its high topography remain unresolved. Here we jointly invert Rayleigh wave dispersion and receiver function data to constrain crustal and uppermost mantle structures ...

Evolution of Sulfur Concentration in the Deep Earth During the Proto‐Earth Growth: First‐Principles Study on the Sulfur Partitioning Between Metal and Silicate at High Pressure and Temperature

Geochemistry, Geophysics, Geosystems
Sulfur (S) is one of the promising light elements that can explain the density deficit of the core. The degree of siderophile nature of S under high pressure and temperature (P,T) is the key to estimating the S content in the core. However, a significant
