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

Geophysical 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

Geophysical 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 ...

Amplifying Variability of the Southern Annular Mode in the Past and Future

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract The Southern Annular Mode (SAM) is the dominant mode of atmospheric variability in the Southern Hemisphere extratropics. While its long‐term positive trend is well‐documented, changes in the amplitude of SAM variability remain poorly understood. Based on reanalysis data and surface‐station observations, we demonstrate that the amplitude of SAM

Migration of Multimodal Deep Crustal Earthquake Swarm Beneath the Abu Volcano Group, Japan

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Earthquakes in the lower crust, where high pressures and temperatures favor ductile deformation, are rare but occasionally occur beneath active volcanic centers, providing insights into deep magmatic processes. We analyze a deep crustal earthquake swarm (February–August 2025) of over 5,000 events beneath the Abu Volcano Group, Japan.

Warming of the Mid‐Troposphere Driven by Evapotranspiration During Compound Heatwave and Drought Events

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract During compound heatwave and drought events (CHDE), a significant amount of soil moisture is released into the atmosphere through evapotranspiration. In this study, we used multi‐source atmospheric water vapor isotope data sets, including satellite and ground‐based observations, to investigate the role of evapotranspired water vapor (EWV ...
