Abstract Several experiments and field observations have demonstrated seismic waves‐induced permeability increases. However, a few revealed significant decreases in the of fractured sandstone after shaking produced by dynamic stresses. In this paper, we analyze tidal responses water level two wells (Junan Dingyuan) situated on near, respectively, Tan‐Lu fault China. The results sampled single well indicate that waves could both increase decrease permeability. addition, our earthquakes...
Abstract Aquifer confinement represents a pivotal property that significantly influences the vulnerability and contamination risk of groundwater resources. Several methods have been proposed for determining aquifer by analyzing response well water level to Earth tides atmospheric tides. In this study, we evaluated performance existing single put forward an optimized comprehensive approach. We compared determination results three with those method using water-level data from 39 earthquake...
Abstract Changes in the permeability of a fault zone are dependent upon frequency seismic waves, and is an important phenomenon whose mechanisms have not be completely elucidated to date. In this study, tidal response water level well Chuan06 was considered as indicator zone, sensitivity changes earthquakes with different epicentral distances were investigated. The results suggested that change induced by waves dependent. addition, based on difference may attributed sizes fractures zone....
Abstract Submarine slope failures are considered as a serious geo‐hazard because they can rupture undersea pipelines, and seafloor engineering facilities be subverted by destroying the seabed stability. widely developed in deep‐water areas of northern continental margin South China Sea, yet mechanisms involved their generation remain poorly known. Observations have proposed that instability due either to decomposition gas hydrate or magma emplacement. Here, we present new high‐resolution 2D...
Soil carbon isotopes (δ13C) provide reliable insights for studying soil turnover at a long-term scale. The Tibetan Plateau (TP), often referred as “the third pole of the earth”, is highly sensitive to global climate change, and exhibits an early warning signal warming. Although many studies detected δ13C variability site scales, there still knowledge gap existing in spatial pattern across TP. In this study, we compiled database 198 topsoil observations from published literatures used...
Tidal drainage effect of confined aquifer is important to well tide interesting many relevant researchers. Through tidal analysis water level monitoring in Chuan06 well, this paper explored the and its influence on tide. It indicated that: changes phase shift (η) amplitude response (A) were attributed transmissivity (T) rather than that storativity (S), isotropic could be effectively described by Hsieh model.
Abstract The trial production of marine natural gas hydrates (NGH) in China is gradually increasing, attracting concerns on related environmental issues. entire regional conditions engineering geological environment must be investigated thoroughly before NGH production. These should defined, among others, terms seabed topography, stratigraphic structure, soil types, physical and mechanical characteristics, hazardous factors distributions, hydrodynamic which provide a variety spatial...
