Influence of Site Amplification Approaches in PSRA: Insights From Five Different Cities

Earthquake Spectra, Volume 42, Issue 4, November 2026.
Regional and national seismic hazard models used in probabilistic seismic risk analysis often rely on generalized proxy‐based site terms to account for ground shaking amplification. This can result in coarse representations of site response, which can introduce bias or additional uncertainty in the associated risk results.

Landslide‐Channel Coupling Controls Asymmetric Flash Flood—Debris Flow Transitions: Insights From an Extreme Rainfall‐Induced Hazard Chain in Yuzhong of China in 2025

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Extreme rainfall‐triggered landslide–flash flood–debris flow hazard chains (LFFDF) are increasingly responsible for hydroclimatic losses worldwide. Although dynamics of individual hazards are established, transition mechanisms within LFFDF governed by coupled landslide–channel responses remain unresolved.

Correcting Unwrapping Errors Toward Reliable Rock Glacier Velocity From InSAR Time Series

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Rock Glacier Velocity is an Essential Climate Variable Permafrost Quantity, providing a quantifiable indicator of mountain permafrost evolution. Despite its wide usage, multi‐temporal InSAR often substantially underestimates rock glacier velocities compared to ground‐based measurements, limiting its reliability.

Large-deformation finite-element modelling of earthquake-induced landslides considering strain-softening behaviour of sensitive clay

Canadian geotechnical journal (Print), 2019
Large-scale landslides in sensitive clays cannot be explained properly using the traditional limit equilibrium or Lagrangian-based finite-element (FE) methods.

Topographic effects on frequency-size distribution of landslides triggered by the Hokkaido Eastern Iburi Earthquake in 2018

Earth, Planets and Space, 2019
This study examined the frequency-size distribution of 6117 landslides spread over 440 km2 in Iburi Subprefecture, Hokkaido, Japan, induced by the Hokkaido Eastern Iburi Earthquake (M w 6.6) on September 6, 2018. The study area is characterized by gently

Shallow Poroelastic Hydrothermal Deformation at Changbaishan Volcano Before the 2020 Unrest Revealed by Sentinel‐1 InSAR Time Series

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Ground deformation of dormant volcanoes provides critical insights into subsurface processes and potential hazards. Here we present Sentinel‐1 Interferometric Synthetic Aperture Radar (InSAR) time series (2015–2020) for Changbaishan volcano, the largest intraplate volcanic system in East Asia. We detect persistent subsidence of up to 3.5 mm/yr

Quantifying Dead‐End Impacts on Radon Signals in Fractured Rocks

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Understanding radon transport in fractured rock is fundamental for interpreting geochemical signals associated with subsurface deformation and fluid transport. The role of dead‐end fractures (DEFs), one key geometric feature of fractured rocks, remains poorly understood.
