The Earth's Greatest Porous Media

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract How deeply does modern meteoric water circulate into the continental crust? How deep is the Earth's Critical Zone (CZ), the top layer of the continental lithosphere that co‐evolves with the atmosphere, hydrosphere, and biosphere, extending from vegetation canopy down to fresh bedrock and the base of active groundwater circulation?

Four Decades of Research at the MADE Site and Beyond: Advancing the Understanding and Modeling of Solute Transport in Heterogeneous Media

open access: yesReviews of Geophysics, Volume 64, Issue 4, December 2026.
Abstract Spatial heterogeneity, manifested as strong variability in hydraulic conductivity (K) within geological formations, exerts a fundamental control on groundwater flow and solute transport. Because K can vary over multiple orders of magnitude in complex three‐dimensional patterns, predicting contaminant plume migration remains a long‐standing ...

A Robust AHP–GIS Based Flood Susceptibility Mapping Using Stochastic Hill‐Climbing Algorithm

open access: yesJournal of Flood Risk Management, Volume 19, Issue 4, December 2026.
ABSTRACT Flooding is one of the most frequent and devastating natural hazards affecting urban areas globally, leading to considerable social, economic, and environmental impacts. In the present study, a novel framework for flood susceptibility mapping is proposed using the stochastic Hill‐Climbing (SHC) method in the Analytical Hierarchy Process (AHP ...

High Resolution Focal Mechanisms and Stress Field Orientation in Southern Italy From Short‐Term Dense Arrays

open access: yesGeophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Understanding fault geometry and mechanics is key to interpreting the seismotectonic setting of a region. We analyze data from a 1‐year dense seismic array deployment in Southern Italy to infer focal mechanisms and stress field from low‐magnitude earthquakes using machine‐learning techniques.

La «Storia di Manfredi» di August Karst. Dalla critica storica sincrona alla lettura contemporanea

open access: yes, 2016
Il quadro complessivo del saggio di August Karst, che è possibile trarre dai giudizi di storici coevi quali Benedetto Croce, Karl Hampe e Thomas Frederick Tout, offre una visione chiara delle valenze e di molte discrepanze nell’inquadramento della ...

Accelerated Atmospheric Drying in Neighboring Rural Areas Across China Associated With Urban Warming

open access: yesGeophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Neighboring rural areas (i.e., rural zones surrounding cities) experience strong urban–rural interactions and provide critical ecosystem services, yet their responses to atmospheric drying remain poorly understood. Here, we quantify urban impacts on vapor pressure deficit (VPD) in neighboring rural areas across China by comparing station ...
