Determination of subsurface lineaments in the Hoang Sa islands using enhanced methods of gravity total horizontal gradient

Vietnam Journal of Earth Sciences, 2022
The Hoang Sa islands, located in the northern part of the East Vietnam Sea, lack information on geological structural boundaries. The gravity data from the global marine gravity model were analyzed using the enhanced total horizontal gradient methods to ...

Seismo-Lineaments in Egypt: Analysis and Implications for Active Tectonic Structures and Earthquake Magnitudes

Remote Sensing, 2022
Quiescent faults may be capable of creating catastrophic earthquakes in locations with moderate and/or low seismic activity, such as Egypt. This study combines structural, remote sensing (RS), geophysical, and seismic activity data to examine and analyze

Delineation of structural lineaments of Southeast Nigeria using high resolution aeromagnetic data

Open Geosciences, 2022
Structural lineaments of Southeast Nigeria were delineated using high-resolution aeromagnetic data. Advanced methods such as enhanced horizontal gradient amplitude (EHGA) involving a 3D model and tilt depth method (TDM) were used in this study.

Derivation of groundwater flow-paths based on semi-automatic extraction of lineaments from remote sensing data [PDF]

Hydrology and Earth System Sciences, 2011
In this paper we present a semi-automatic method to infer groundwater flow-paths based on the extraction of lineaments from digital elevation models. This method is especially adequate in remote and inaccessible areas where in-situ data are scarce.
