Rapid urbanization and population growth in Hanoi city raise the demand for groundwater risk of land subsidence. This study is first to conduct a long-term interferometric synthetic aperture radar (InSAR) analysis with different SAR sensors including ALOS, COSMO-SkyMed Sentinel-1 evaluate spatiotemporal evolution subsidence between 2007 2018. The results show that Central had been diminishing d...

S U M M A R Y Long-term volcanic subsidence provides insight into intereruptive processes, which comprise the longest portion of the eruptive cycle. Ground-based geodetic surveys of Medicine Lake Volcano (MLV), northern CA, document subsidence at rates of∼−10 mm yr−1 between 1954 and 2004. The long observation period plus the duration and stable magnitude of this signal presents an ideal opport...

Nowadays, satellite radar interferometry method plays an important role in calculating natural and artificial displacements, including displacements caused by floods, earthquakes, landslides, drilling of unauthorized wells, drilling of urban tunnels, etc. Metro tunneling is very important due to the importance of preventing irreparable financial and human losses. In Tehran, especially due to th...

Abstract. Ground ice is foundational to the integrity of Arctic ecosystems and infrastructure. However, we lack fine-scale ground maps across almost entire Arctic, chiefly because there no established method for mapping ice-rich permafrost from space. Here, assess whether remotely sensed late-season subsidence can be used identify permafrost. The idea that, towards end an exceptionally warm sum...

Land subsidence in the Bandung basin, West Java, Indonesia, is characterized based on differential interferometric synthetic aperture radar (DInSAR) and interferometric point target analysis (IPTA). We generated interferograms from 21 ascending SAR images over the period 1 January 2007 to 3 March 2011. The estimated subsidence history shows that subsidence continuously increased reaching a cumu...

In this paper, the decision-making information of subsidence area for twenty years is extracted, using Landsat multi-band and multitemporal remote sensing data, SPOT 5 texture features, DEM elevation, the methods of data fusion and principal component analysis and GIS technology, thereby the spatial and temporal distribution of change of subsidence area in mining is acquired from years 1987 to ...

Subsidence seriously affects the structural stability and safety of pavements foundation soils. In heavy-loaded pavements, there is a risk floor sinking further construction collapse; hence, need to develop efficient methodologies detect subsidence earlier. This work proposes use ground penetrating radar (GPR) as solution non-invasively inspect subsoil. Furthermore, interpretation GPR data argu...

Abstract The exploitation of the XIV horizon, in two slices, across entire mining perimeter Slănic Prahova Salt Mine until end 2059 will result amplification surface subsidence, already affected by operations Victoria, Cantacuzino, and Old Mines. Systematic annual monitoring ground deformation has been conducted since 2004 through geometric leveling along selected representative alignments, whi...
