Explainable Seismic Event Discrimination: Improved Explainability With Vision Transformers
Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.Abstract The discrimination of seismic events traditionally relies on manual expert analysis or cross‐correlation techniques for pattern recognition. Although flexible algorithms from deep learning, such as convolutional neural networks, have demonstrated high discrimination accuracy for different seismic event origins based on spectral characteristics,

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 ...

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.Abstract Both mantle plumes and passive margin extension have been recognized as crucial mechanisms governing intracontinental volcanism and lithospheric evolution. However, the synergistic interactions between these two processes in modulating lithospheric modification remain poorly constrained.

Ionospheric disturbances around the time of the Ms7.0 Lushan earthquake
Geodesy and Geodynamics, 2013 Variations of Vertical Total Electron Content (VTEC) in the ionosphere are investigated around the time of the Ms7. 0 Lushan earthquake. A time-series analysis shows an anomalous VTEC increase 15 days before as well as some anomalous VTEC decreases 5 ...

Analysis of Shear Wave Splitting Patterns in Alaska: Evidence for Strong Intra‐Slab Anisotropy
Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.Abstract Shear wave splitting (SWS) patterns at subduction zones are often interpreted by complex mantle flow above or below the slab. However, our recent previous work shows dipping anisotropic slabs can explain observed patterns in Japan. Here, we extend this analysis to the Alaska subduction zone, using 2,567 high‐quality teleseismic SWS ...

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.Abstract We use distributed acoustic sensing along a submarine fiber‐optic cable to provide the first high‐resolution two‐dimensional shear‐wave velocity (Vs) model of the North Anatolian Fault (NAF) in the Marmara Sea. Using 7 days of ambient noise recordings, we extract Scholte wave dispersion curves via slant‐stacking and invert for the Vs structure,

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 52, Issue 20, 28 October 2025.Abstract We calculate cross‐component correlations and receiver functions from teleseismic earthquakes recorded by a seismic nodal array deployed in the central Vienna Basin, Austria. The two methods show similar results. Those results highlight two main layer boundaries between the surface and 15 km depth.

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
