“…The anchored cable and pipe (free standing and counterweighted) extensometers have been used widely in a number of successful subsidence investigations. More recently, dual-stage counterweighted pipe extensometers ( Figure 5) have been used to measure compaction simultaneously in two depth intervals (Heywood, 1993;Metzger et al, 2002). Counterweighted pipe extensometers are capable of measurement resolutions of 0.01 -0.1 mm (Riley, 1969).…”

Regional aquifer-system compaction and land subsidence accompanying groundwater abstraction in susceptible aquifer systems in the USA is a challenge for managing groundwater resources and mitigating associated hazards. Developments in the assessment of regional subsidence provide more information to constrain analyses and simulation of aquifer-system compaction. Current popular approaches to simulating vertical aquifer-system deformation (compaction), such as those embodied in the aquitard drainage model and the MODFLOW subsidence packages, have proven useful from the perspective of regional groundwater resources assessment. However, these approaches inadequately address related local-scale hazards-ground ruptures and damages to engineered structures on the land surface arising from tensional stresses and strains accompanying groundwater abstraction. This paper presents a brief overview of the general approaches taken by the U.S. Geological Survey toward understanding aquifer-system compaction and subsidence with regard to a) identifying the affected aquifer systems; b) making regional assessments; c) analyzing the governing processes; and d) simulating historical and future groundwater flow and subsidence conditions. Limitations and shortcomings of these approaches, as well as future challenges also are discussed.Keywords: Subsidence, aquifer-system compaction, aquitard drainage, MODFLOW, poroelastic deformation.

“…The strain registered at 90-m depth fluctuated around a positive strain of~203 με, implying that delayed deformation of At-III had nearly ended. Combined, these results demonstrate that the spatial continuity of FO strains allows for identifying very localized deformation, whereas such features may not be captured by traditional instrumentation such as extensometers (Hwang et al, 2008;Metzger et al, 2001;Riley, 1969).…”

“…Vertical deformation is currently measured by various techniques such as precise leveling, interferometric synthetic aperture radar (InSAR), global navigation satellite system (GNSS), and extensometry (Galloway & Burbey, ). Satellite imagery and space geodetic techniques measuring land‐surface elevation changes have allowed for mapping and monitoring detailed surface deformation over large areas (Amelung et al, ; Massonnet & Feigl, ; Shirzaei & Bürgmann, ), whereas subsurface strata deformation is often identified and characterized using extensometers (Hwang et al, ; Metzger et al, ; Riley, ). Despite considerable effort, however, recording detailed distributions of vertical deformation using traditional extensometers is sometimes challenging, mainly due to the inadequate information provided by spatially discrete measuring points.…”

Vertical deformation can be revealed by various techniques such as precise leveling, satellite imagery, and extensometry. Despite considerable effort, recording detailed subsurface deformation using traditional extensometers remains challenging when attempting to detect localized deformation. Here we introduce distributed fiber optic sensing based on Brillouin scattering as a geophysical exploration method for imaging distributed profiles of vertical deformation. By examining fiber optic cable‐soil interaction we found a threshold in confining pressure to achieve a strong cable‐soil coupling, thus validating data collected from a borehole‐embedded fiber optic cable deployed in Shengze, southern Yangtze Delta, China. Clear‐cut strain profiles acquired from November 2014 to December 2016 allowed us to pinpoint where compaction or rebound was actively occurring and examine strain responses at various locations along the entire cable length. We suggest that distributed fiber optic sensing can complement with extensometry and remote sensing techniques for improved monitoring of vertical deformation.

“…The area faced several problems in the past, mainly due to inundation (especially during the years 1968, 1974, 1976, 1979, and 1999). By taking into account all the possible causes for subsidence, the most significant seem to be the geological structure and the water pumping [23,24]. However, the lack of correlation in space and in time between fluctuations of piezometric levels, topographic changes and pumping indicates that the observed subsidence should be regarded as the cumulative effect of several factors, including consolidation of near-surface sediments due to the decline of the piezometric level and the partial abandonment of the delta, oxidation of peat soils in the vadose zone, synsedimentary deformation (faulting and flow) and loading-induced consolidation of deeper sediments [25].…”

Remote Sensing and Geographic Information Systems (GIS) Contribution to the Inventory of Infrastructure Susceptible to Earthquake and Flooding Hazards in North-Eastern Greece

For civil protection reasons there is a strong need to improve the inventory of areas that are more vulnerable to earthquake ground motions or to earthquake-related secondary effects, such as landslides, liquefaction or soil amplifications. The use of remote sensing and Geographic Information Systems (GIS) methods along with the related geo-databases can assist local and national authorities to be better prepared and organized. Remote sensing and GIS techniques are investigated in north-eastern Greece in order to contribute to the systematic, standardized inventory of those areas that are more susceptible to earthquake ground motions, to earthquake-related secondary effects and to tsunami-waves. Knowing areas with aggregated occurrence of causal (“negative”) factors influencing earthquake shock and, thus, the damage intensity, this knowledge can be integrated into disaster preparedness and mitigation measurements. The evaluation of satellite imageries, digital topographic data and open source geodata contributes to the acquisition of the specific tectonic, geologic and geomorphologic settings influencing local site conditions in an area and, thus, estimate possible damage to be suffered
