Foundations may undergo severe distress during an earthquake. One such example of foundation failure involving toppling of apartment blocks due to liquefaction during the 1964 Niigata Earthquake is presented in Figure 1. Earthquake effects on shallow and deep foundations are accounted for by designing them structurally to provide necessary strength and ensure serviceability. Strength considerat...

By performing fully 3D symmetry-unrestricted Skyrme-Hartree-FockBogoliubov calculations, we discuss shape coexistence and possibility of exotic deformations simultaneously breaking the reflection and axial symmetries in proton-rich N = Z nuclei: Ge, Se, Kr, Sr, Zr and Mo. Results of calculation indicate that the oblate ground state of Se is extremely soft against the Y33 triangular deformation,...

Volcano monitoring uses knowledge of volcanic processes and extensive data gathering to analyze areas of volcanic activity. The main goal is to learn the nature of the volcano, the magmatic processes occurring, and the likelihood of a future eruption. Volcano monitoring centers around three aspects of volcanic processes: ground deformation, seismic activity, and gas emissions. These techniques ...

This work presents an investigation to determine ground deformation based on an integration of DInSAR Time-Series (DTS) and Persistent Scatterer Interferometry (PSI) techniques aiming at detecting high rates of linear and non-linear ground movement. The combined techniques were applied in an open pit iron mine located in Carajás Mineral Province (Brazilian Amazon region), using a set of 33 Terr...

[1] We present a new approach to extracting spatially and temporally continuous ground deformation fields from interferometric synthetic aperture radar (InSAR) data. We focus on unwrapped interferograms from a single viewing geometry, estimating ground deformation along the line-of-sight. Our approach is based on a wavelet decomposition in space and a general parametrization in time. We refer t...

SAR differential interferometry is an innovative space-based measurement technology for ground deformation. Under inclement Qinghai-Tibet plateau environment, monitoring and analysis of railway subgrade deformation using satellite interferometry in plateau permafrost region has very important engineering significance for stability evaluation and safety management. In the paper, a brief descript...

Spatiotemporal deformation of existing sinkholes and the surrounding region in Wink, TX are probed using time-series interferometric synthetic aperture radar (InSAR) methods with radar images acquired from the Sentinel-1A satellite launched in April 2014. The two-dimensional deformation maps, calculated using InSAR observations from ascending and descending tracks, reveal that much of the obser...

In this paper, a new function model for determining the minimum and maximum detectable deformation gradient in synthetic aperture radar interferometry (InSAR) with Envisat ASAR images is developed. The model incorporates the parameters of both interferometric coherence and multilook operator for 1, 5 and 20, rather than the interferometric coherence only in previous studies. Experimental result...
