Plume‐Fed Magmatic Fluids Weakened Crust and Promoted a Large Intraplate Earthquake in Northern Hainan (South China)

Abstract Large intraplate earthquakes are paradoxical because they occur far from active plate boundaries. Northern Hainan Island (South China) hosts the 1605 Qiongbei M7.5 earthquake within a volcanic province linked to the Hainan mantle plume. New shear‐wave velocity images rev...

Identification of Landslide Risks in the Subtropical Hilly Regions of Southern China Using Integrated Multi-Source Synthetic Aperture Radar Interferometry and Machine Learning

The subtropical hilly regions of southern China are characterized by dense vegetation and highly concealed landslides, making it difficult for traditional, single-source remote sensing methods to meet disaster prevention needs. The core scientific contribution of this study is th...

How Much Water Can Be Seasonally Buffered by China's Largest Floodplain Lake? A Refined Estimate From SWOT

Abstract Poyang Lake, China's largest floodplain lake, plays a crucial role in regional hydrology by seasonally regulating water to mitigate floods and sustain extensive wetland ecosystems. However, complex hydrodynamics and significant spatial hydraulic gradients often invalidat...

Fault-Controlled Permeability Anisotropy and Sustainable Exploitation of Typical Medium-Low Temperature Sedimentary Basin-Type Geothermal Reservoir in Tianjin, Dongli Lake, China

The structurally complex Cangdong fault zone controls the medium- to low-temperature geothermal potential of the Dongli Lake field in Tianjin, China. Previous assessments in Chinese sedimentary basins predominantly employed simplified volumetric methods that cannot capture transi...

Water-Induced Shear-Strength Degradation of Coal-Measure Rocks and Its Engineering Implications: A Case Study of the Fushun West Open-Pit Mine, China

Slopes excavated in coal-measure strata are prone to rainfall-induced landslides because water-induced disturbances progressively degrade rock-mass shear strength. This study investigated six coal-measure lithologies from the unloading zone of the Fushun West Open-Pit Mine using...

Groundwater quality assessment, health risk assessment, and source apportionment in the Xin’an River Basin, China, during the wet season

To analyze groundwater quality and its influencing factors in the Xin'an River Basin and to support the pilot ecological compensation mechanism, 150 groundwater samples were collected in the wet season from May to June, 2021. This study investigated groundwater quality during the...

Potential and Insight: Sealing Potential of Low‐Permeability Basalt Interlayer in Mudstone Caprock for CO 2 Storage in Sandstone Aquifer

ABSTRACT When CO 2 is sequestered in deep aquifers of sedimentary basins, mudstone or shale is usually used as a caprock. When the caprock contains low‐permeability basalt interlayers, its sealing potential could be improved. This study utilized geological data from the Jianghan...

Irrigation Regimes Shape Vertical Salt Distribution in Coastal Saline–Alkali Farmlands: A PLS-SEM Analysis of Direct Ion Input and Physicochemical Pathways

Soil salinization constrains agricultural sustainability in coastal low plain regions, yet the mechanisms regulating salt spatial heterogeneity under different water management regimes remain unclear. This study investigated soil soluble ion distribution and influencing factors a...

Source identification and risk assessment of potentially toxic elements in surface soil of townships in the northwest Hebei region

Abstract Soil environmental quality in townships is related to the development of rural revitalization and the smooth flow of urban-rural integration and development. However, the quality of soil environment in townships may be exposed to potential risks of potentially toxic elem...

Bibliometric analysis of groundwater remediation research in China and the United States: a comparative insight

The United States and China were the two most productive countries in global groundwater pollution remediation research, having accumulated substantial findings and practical experience through sustained funding and long-term scientific investment. However, a comprehensive compar...

Hydrochemical Characteristics and Evolution of Groundwater in Weibei Plain Based on Hydrogeological Zoning (China)

The Weibei Plain, characterized by its complex stratified aquifer system and extensive brine resources, faces severe groundwater salinization. Unraveling the precise evolutionary mechanisms of diverse hydrochemical types across varying depths and geomorphological zones remains a...

Short-Term Ground Gust Prediction Based on Fusion of Ground and High-Altitude Meteorological Data and Differential Polynomial Modeling

Accurate Short-term forecasting of gusts at 10 m above ground level is challenging because gridded meteorological variables exhibit persistence, nonstationarity, and abrupt transitions. This study proposes a Temporal Adaptive Difference Polynomial Network (TADPN) using 8760 hourl...

Hydrological Drought Modeling Under the Impact of Climate Change in the Luanhe River Basin: A Prediction Study

Against the backdrop of climate change and compounded by human activities, increasing water scarcity has triggered a series of drought disasters, which have already severely impacted both ecological environments and socioeconomic production. The SWAT model, recognized for its str...
