Quantifying the Lifespan of 3D Flood Structures: Unlocking the Potential of Flood Detention Areas for Enhanced Flood Control in China

open access: yesWater Resources Research, Volume 61, Issue 11, November 2025.
Abstract The escalating frequency and magnitude of floods pose significant challenges to traditional flood control measures with fixed defense capacities, such as levees, dams, and reservoirs. Flood Detention Areas (FDAs) have been widely implemented in many countries as solutions to extreme flood events, functioning by temporarily holding excess ...

The 2025 MW7.0 Dingri Earthquake: Conjugate Normal Faulting of a Graben Structure in the Southern Xainza‐Dinggye Rift

open access: yesGeophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract The 2025 MW ${M}_{W}$7.0 Dingri earthquake, which struck southern Tibet on 7 January 2025, provides kinematic insights into extensional tectonics in the region. We use Sentinel‐1 and Lutan‐1 Synthetic Aperture Radar (SAR) data sets to analyze the coseismic displacement fields of this event.
