Nineteen percent of the global population may face a high probability subsidence

Analyses of areal variations in the subsidence and rebound occurring over stressed aquifer systems, in conjunction with measurements of the hydraulic head fluctuations causing these displacements, can yield valuable information about the compressibility and storage properties of the aquifer system. Historically, stress-strain relationships have been derived from paired extensometer/piezometer i...

Spatial variation and temporal changes in ground subsidence over the Nobi Plain, Central Japan, are assessed using GIS techniques and ground level measurements data taken over this area since the 1970s. Notwithstanding the general slowing trend observed in ground subsidence over the plains, we have detected ground rise at some locations, more likely due to the ground expansion because of recove...

In this study we investigate the spatial variation in vertical land motion (VLM) along the coast of Singapore over the past two decades and we examine the impact of spatially variable VLM on relative sea level trends. For that, we use an integrated approach based on the merging of terrain displacement velocities estimated by time series of interferometric synthetic aperture radar (InSAR) data a...

In an environment, one of the natural geological hazards is land surface subsidence. Underground mining and subsurface coal fires are primarily responsible for subsidence land. Activities, such as, over-exploitation coal, minerals, groundwater petroleum resources, depillaring existing galleries water logging relinquished major factors resulting in The deformation measured terms change ground el...

It is well known that the metropolitan area of Bangkok, Thailand, has been subsiding during the past decades. This ground deformation has been monitored using leveling networks on annual basis since 1978. However, the employed technique is costly, time-consuming, and able to monitor only on a limited number of benchmarks. InSAR (Interferometric Synthetic Aperture Radar), which can provide sub-c...
