Disturbance legacies in arid environments shape recovery of former agricultural land

Restoration Ecology, EarlyView.
Abstract Introduction Increasingly, arid agricultural land is being permanently taken out of irrigated production due to more frequent drought, higher temperatures, and the overconsumption of groundwater, with important ramifications for ecological recovery.

Room to regenerate: microhabitats and the recruitment niche as drivers of mountain woodland restoration

Restoration Ecology, EarlyView.
Abstract Introduction Natural regeneration is an efficient, minimal‐intervention approach essential for facilitating resilient, self‐sustaining ecosystems during woodland restoration. However, recruitment can be slow, uncertain, or highly restricted, particularly in mountain woodland systems where tree planting and large herbivore management are ...

Velocity structure tomography analysis in southern Hebei Province

地震科学进展
The destruction of cratons is one of the key research objects of geophysicists. According to China Earthquake Networks Center, small and medium-sized earthquakes have occurred more frequently in southern Hebei in recent years than before.

High-resolution tomography of P-wave velocity structures in the Haicheng region: Implications for the seismogenesis of the 1975 MS7.3 Haicheng earthquakeKey points

Earthquake Science
The 1975 Haicheng earthquake represents the first successful prediction of a major earthquake in China and is the only earthquake forecast officially recognized by the United Nations. Understanding the crustal structure in the Haicheng region is critical

Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...

The Earth's Greatest Porous Media

Perspectives 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?

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.

Surface Consistent Seismic Hazard Assessment in the Shillong Plateau, Northeast India: A Probabilistic Approach Using Multiple Source Models and a Logic Tree Framework

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2855-2879, September 2026.
ABSTRACT We perform probabilistic seismic hazard analysis (PSHA) in the Shillong Plateau by clubbing the up‐to‐date earthquake data and seismotectonic properties of the study area. Twenty‐one areal seismic sources are delineated based on the updated earthquake catalog, tectonic, and fault plane solutions.

Multi‐Hazard Shaking‐Tsunami Fatality Risk Estimation for Coastal Communities

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2618-2633, September 2026.
ABSTRACT This study develops a multi‐hazard fatality risk model for a coastal community (Tofino) on Vancouver Island, Canada, subjected to earthquake‐tsunami threats from the Cascadia subduction megathrust events. The model incorporates variable population distributions and uncertain fatality rate models, in addition to other key model components, such
