Large‐Scale Interseismic Strain Mapping of the NE Tibetan Plateau From Sentinel‐1 Interferometry

Journal of Geophysical Research: Solid Earth, Volume 127, Issue 6, June 2022., 2022
Abstract The launches of the Sentinel‐1 synthetic aperture radar satellites in 2014 and 2016 started a new era of high‐resolution velocity and strain rate mapping for the continents. However, multiple challenges exist in tying independently processed velocity data sets to a common reference frame and producing high‐resolution strain rate fields.

Energy evolution‐based damage quantification and failure prediction of fault zone tunnel lining concrete: A novel acoustic emission–strain energy coupling approach

Deep Underground Science and Engineering, EarlyView.
This study investigates the damage evolution and failure mechanisms of tunnel lining concrete in active fault zones through uniaxial compression tests integrated with acoustic emission (AE) monitoring. A strong linear correlation is identified between the AE cumulative absolute energy and the total strain energy, providing a reliable energy‐based ...

Do Shallow Slip Deficits Reflect Fault Structural Maturity or Modeling Choices? A Comparative Analysis of Tibetan Strike‐Slip Earthquakes

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract InSAR‐constrained finite fault slip models are often used to characterize fault geometries and slip distributions of large continental earthquakes. A common feature of these models is a decrease in slip near the surface, commonly expressed as a percentage shallow slip deficit (SSD).

Predicting Seismic Intensity Using Machine Learning With Ancillary Data: Evidence From Destructive Earthquakes in China

Engineering Reports, Volume 8, Issue 9, September 2026.
A machine learning framework integrating multisource seismic, social, and geographic data accurately predicts kilometer‐scale seismic intensity, enabling rapid postearthquake damage assessment during data‐scarce “black‐box” periods. ABSTRACT Accurate and rapid assessment of seismic intensity is crucial for postearthquake emergency response.
