Spatial modeling of ground subsidence susceptibility along Al-Shamal train pathway in Saudi Arabia

Open Geosciences, 2021
Al-Shamal train pathway, which is extended between Saudi Arabia and Jordan, is prone to geo-hazards due to the geological features, proximity to faults, earthquake epicenter, and the human activities along the pathway. The objectives of this study are to

Methods for monitoring land subsidence and earth fissures in the Western USA [PDF]

Proceedings of the International Association of Hydrological Sciences, 2015
Depletion of groundwater resources in many deep alluvial basin aquifers in the Western USA is causing land subsidence, as it does in many regions worldwide.

Impact of rock salt creep law choice on subsidence calculations for hydrocarbon reservoirs overlain by evaporite caprocks [PDF]

, 2016
Accurate forward modeling of surface subsidence above producing hydrocarbons reservoirs requires an understanding of the mechanisms determining how ground deformation and subsidence evolve.

Characteristics of Rebound Deformation Caused by Groundwater Level Recovery: A Case Study of the Yuhuazhai Area in Xi’an, China

Applied Sciences
A rise in the water level may result in different vertical rebound levels of the ground surface, adversely affecting buildings. Ground rebound occurred in the Xi’an Yuhuazhai area from 2018 to 2019, but the soil’s deformation characteristics remain ...

Different scale land subsidence and ground fissure monitoring with multiple InSAR techniques over Fenwei basin, China [PDF]

Proceedings of the International Association of Hydrological Sciences, 2015
Fenwei basin, China, composed by several sub-basins, has been suffering severe geo-hazards in last 60 years, including large scale land subsidence and small scale ground fissure, which caused serious infrastructure damages and property losses. In this

Effects of mining subsidence observed by time-lapse seismic reflection profiling [PDF]

, 1995
Extracting coal from underground mineworkings causes the overlying rocks to subside with associated changes in the stress regime. The aim of the study reported here was to apply the surface seismic reflection method to study the effect of subsidence on ...

Fault and magmatic interaction within Iceland's western rift over the last 9kyr [PDF]

, 2003
We present high-resolution 'Chirp' sub-bottom profiler data from Thingvallavatn, a lake in Iceland's western rift zone. These data are combined with stratigraphic constraints from sediment cores to show that movement on normal faults since 9 ka are ...

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

FEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...
