Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract The origin of a binary‐mixing of DM and EM1 sources for the Cenozoic intraplate volcanism in eastern Northeast China is yet unclear. Seismic attenuation imaging is a tool that can shed light on this question. Here we present the first map of teleseismic P‐wave attenuation across Northeast China.

“Hearing” Wind Speed: Ground Wind Measurement Using Deep Learning From Surveillance Audio
Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract This study presents a novel method for measuring ground wind speed (WS) using audio data collected from surveillance cameras. The continuous wavelet transform is employed to model wind sounds and capture the dynamic variations over time. A deep‐learning model integrating attention‐enhanced Convolutional Neural Network and Bidirectional Gated ...

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Bedrock fault scarps and their associated colluvial wedges provide key evidence for reconstructing paleoearthquakes. We apply rock surface luminescence dating to a bedrock scarp on the Huashan fault in central China, using OSL‐depth profiles (DPs) from multiple heights. Results reveal two coseismic displacements of 6.8 and >1.0 m.

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

Risk‐Targeted Seismic Design Maps for Mexico
Earthquake Engineering &Structural Dynamics, Volume 55, Issue 2, Page 336-349, February 2026.ABSTRACT Risk‐targeted seismic design maps for Mexico are presented. Risk‐targeted approach establishes an acceptable risk level, measured with the annual collapse probability, to determine seismic design coefficients. Seismic design maps are calculated for an annual probability of collapse of 1 × 10−4 and 2 × 10−4.

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 ...

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.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.Abstract Deep mantle downwellings are typically located away from the two Large Low‐Velocity Provinces (LLVPs) in Earth's mantle. Geodynamic models based on global seismic tomography generally predict that convective flow at the core‐mantle boundary spreads laterally away from downwelling regions and toward LLVPs.

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 ...
