Why Firn Quakes

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Snow dampens sounds, but anecdotal reports concisely describe audible propagating collapse events—firnquakes—in Antarctic and Arctic snowfields. We propose combining granular and continuum mechanics to form a testable theory for conditioning, triggering, and propagation of firnquakes consistent with scarce data.

Abrupt Along‐Strike Change of Shallow Seismicity in Central and Southern Myanmar: Insights From High‐Resolution Local‐Earthquake Catalogs and Focal Mechanisms

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Myanmar's high seismic hazard is underscored by the 2025 Mw 7.7 earthquake on the Sagaing Fault, yet its seismicity patterns and underlying controls remain poorly understood. Using new seismic data from the 2nd‐phase array of the China‐Myanmar Geophysical Survey in the Myanmar Orogen, we construct a high‐resolution catalog of 1,819 local ...

The Role of Normal Stress and Shear Stress Heterogeneity in the Inferred Depth‐Independence of Stress Drop

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Earthquake stress drops are inferred to be independent of source depth, contradicting linear scaling predictions for earthquakes as frictional stick‐slip instabilities that assume increasing fault normal stress due to overburden. Here, we examine the scaling between averaged stress drops and increasing normal stress for simulated earthquake ...

Sound Velocities of FeO‐Bearing Ringwoodite and Majorite: Implication for Martian Mantle Seismic Profiles

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Compressional and shear wave velocities (Vp, Vs) of candidate Martian deep‐mantle minerals, FeO‐rich ringwoodite ((Mg0.66Fe0.34)2SiO4) and majorite (Mg0.75Fe0.10Al0.26Ca0.07Si0.84O3), were measured up to 25 GPa and 700 K using Brillouin light scattering coupled with externally‐heated diamond anvil cells.
