Circumpolar raster grids of permafrost extent and geohazard potential for near-future climate scenarios [PDF]

, 2018
One of the consequences of warming climate is rising ground temperatures and degradation of perennially frozen ground, permafrost. Thawing of near-surface permafrost can cause geohazards, such as ground subsidence, thaw settlement and thermokarst ...

Creation of a Landslide Susceptibility Map Using Short‐Term Data From the July 2018 Heavy Rainfall in Southern Hiroshima Prefecture

Geological Journal, EarlyView.
This work advances landslide susceptibility mapping by incorporating short‐term trigger data with landscape susceptibility mapping. We also examine the importance of downsampling, watershed delineation and geospatial correlations in evaluating outcomes.

Bio‐Derived Carbon Nanoparticles: A Green Amendment for Alleviating Heavy Metals in Soil–Plant Systems

Land Degradation &Development, EarlyView.
ABSTRACT Heavy metal (HM) contamination of soil–plant systems poses persistent ecological and health risks, driving interest in nanoparticle‐based remediation. Although conventional chemically synthesized nanoparticles (CSNPs) are effective, their energy‐intensive production and residual toxicity limit sustainable deployment.

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.
