Responses of Stream Geomorphic Indices to Piedmont Fault Activity in the Northern Segment of the Red River Fault Zone

Remote Sensing, 2023
Based on a digital elevation model (DEM) and GIS technology, we extracted and analyzed stream geomorphic indices—such as the slope, relief degree of the land surface (RDLS), hypsometric integral (HI) and channel steepness index (ksn)—of the Cangshan ...

The role of gas emissions (He, Rn, and CO2) from fault zones in understanding fault and seismic activity

Frontiers in Earth Science
Active fault zones are critical pathways for the migration of deep fluids to the Earth’s surface, carrying gases such as He, Rn, and CO2 that provide evidence for the physical and chemical dynamics of the Earth’s interior.

Conservative Evaluation of Fault Displacement Hazard for a Nuclear Site in Case of Insufficient Data on the Fault Activity

Geosciences
The safety regulations require periodic reviews of the site hazards when operating nuclear power plants. If any indications of Quaternary fault activity are revealed, the fault displacement hazard should be evaluated.

Influence of Regional Erosion and Sedimentary Loading on Fault Activities in Active Fold-Thrust Belts: Insights From Discrete Element Simulation and the Southern and Central Longmen Shan Fold-Thrust Belt

Frontiers in Earth Science, 2021
Four groups of discrete element models (DEMs) were set-up to simulate and analyze the influence of regional erosion and sedimentary loading on the formation and spatial-temporal evolution of faults in the southern and central Longmen Shan (LMS) active ...

怀涿盆地北缘断裂带土壤气体地球化学特征

Dizhen xuebao, 2023
在河北怀涿盆地的郝家坡和小水峪布设两条测线开展了四期土壤气Rn，CO2和Hg的浓度测量，并基于此研究该盆地北缘断裂带南西段和北东段土壤气地球化学特征的空间分布差异及其与断裂活动的关系。结果显示：郝家坡剖面土壤气Rn，CO2和Hg的浓度平均值分别为8 371.16 Bq/m3，0.85 %和14.82 ng/m3；小水峪剖面土壤气Rn，CO2和Hg的浓度平均值分别为2 813.18 Bq/m3，0.42 %和13.08 ng/m3，可见郝家坡地区土壤气Rn，CO2和Hg的浓度平均值均高于小水峪地区 ...
