Resilience can be interpreted as the comprehensive ability of a system to prepare for, absorb, and recover from external or internal disturbances and shocks. In the context of human mobility, resilience therefore refers to the ability of people’s movements within and between cities to cope with and adapt to disruptive events, such as natural disasters. ...

Both the geometric and spectral information of the target are available with the hyperspectral light detection and ranging (LiDAR) in a single measurement. This advanced technique extends the scope of imaging spectroscopy to spectral three-dimensional (3D) sensing. However, two major geometric radiative effects exist in hyperspectral LiDAR, namely, the distance effect and incidence angle effect, ...

Large earthquakes generally produce ground deformation that can be measured by geodetic instruments. Geophysicists can use these measurements to invert the earthquake source parameters, that is, to recover the earthquake slip on the ruptured fault. However, the conventional inversion of geodetic data does not fully resolve the geometry of the broken fault at depth. Wei ...
