Ionospheric VTEC anomalies before Ms7.1 Yushu earthquake
Geodesy and Geodynamics, 2011 Vertical total electron content is examined to check whether the Ms7.1 Yushu earthquake on April 14, 2010, may have caused any anomalous ionospheric changes. The result shows two TEC increases over the epicenter vicinity on April 1 and 5; these anomalies

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

Red giant seismology: Observations
EPJ Web of Conferences, 2013 The CoRoT and Kepler missions provide us with thousands of red-giant light curves that allow a very precise asteroseismic study of these objects. Before CoRoT and Kepler, the red-giant oscillation patterns remained obscure.

Geophysical 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
Geophysical 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
Geophysical 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.

Frequency dependent attenuation of seismic waves for Delhi and surrounding area, India
Annals of Geophysics, 2015 The attenuation properties of Delhi & surrounding region have been investigated using 62 local earthquakes recorded at nine stations. The frequency dependent quality factors Qa (using P-waves) and Qb (using S-waves) have been determined using the ...

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

Aerial Seismology Using Balloon-Based Barometers
IEEE Transactions on Geoscience and Remote Sensing, 2019 Seismology on Venus has long eluded planetary scientists due to extreme temperature and pressure conditions on its surface, which most electronics cannot withstand for mission durations required for ground-based seismic studies.

Building damages in Deyang city by the 2008 Wenchuan earthquake
Geodesy and Geodynamics, 2011 The Ms8.0 Wenchuan earthquake in 2008 caused huge casualties, economic losses, and building damages, which are analyzed. The results show that damages of houses designed according to the current seismic code were significantly smaller than those without ...
