Evidence for Virtual Source‐Receiver Refractions in Cross Correlations of Infrasonic Ambient Noise

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Seasonal variability in source activity and atmospheric temperature were retrieved from 11 years of infrasonic ambient noise. Variable lag times between an array and single microbarometer were obtained from envelopes of cross‐correlation functions. Beamforming and one‐bit normalization significantly enhanced the stationary phase.

Lake Unloading Drives Fault Slip and Rift Asymmetry in Southern Tibet

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The extent to which surface processes drive continental deformation remains a pivotal question in geodynamics. Here, we demonstrate that Late Quaternary lake‐water unloading is a primary driver of fault slip and rift asymmetry in southern Tibet.

Characterization of Crustal Deformation During the May 2021 Nyiragongo Eruption Using InSAR and GNSS Data

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract We analyze Interferometric Synthetic Aperture Radar (InSAR) and Global Navigation Satellite System (GNSS) data to characterize ground deformation and dike opening associated with the May 2021 Nyiragongo eruption. Despite documented eruptions in 1977 and 2002, Nyiragongo's magmatic system and its interaction with regional rifting remain poorly ...

Ambient‐Noise Multicomponent Multimodal Dispersion Characteristics in Thick Sedimentary Basins

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Ambient noise cross‐correlations enable the extraction of multimodal surface waves, yet resolving their complex dispersion characteristics is essential for robust subsurface imaging. Using dense array data from the North China Plain, we resolve multicomponent multimodal Rayleigh and Love wave dispersion with unprecedented detail.

A Seismically Active Shear Zone in the Uppermost Mantle Beneath the Canadian Rockies

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Continental mantle earthquakes are uncommon but hold important clues for understanding lithospheric rheology. Few of these earthquakes (<10) have been documented in western North America, though it is likely more exist owing to difficulties in resolving focal depth for small earthquakes.

Multi‐Scale Decomposition for Skillful All‐Season MJO Prediction With Deep Learning

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract The Madden‐Julian Oscillation (MJO) is a key intraseasonal atmospheric pattern in the tropics, significantly influencing global weather and extreme events. Accurate subseasonal forecasts depend on reliable MJO prediction, and recent artificial intelligence (AI)‐based models have shown great promise for enhanced prediction of MJO index. However,

Rupture Dynamics of the 2025 Mw 7.7 Myanmar Earthquake: A Bilateral Supershear Rupture on Unusually Long Fault Superhighway

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract The 2025 Mw 7.7 Myanmar earthquake ruptured the central Sagaing fault, a previously identified seismic gap with high seismic potential. Here, we perform hundreds of 3D dynamic rupture simulations to investigate the rupture dynamics, constrained by near‐fault strong‐motion waveforms, optical and SAR pixel offsets, and a kinematic source model ...
