Abstract:Monitoring the actual surface deformation caused by sub-surface fluid activities is crucial for comprehending the subsurface fluid mutation process. Incorporation of InSAR observations in a prior volume strain model (VSM) can facilitate the estimation of sub-surface fluid volumetric changes and threedimensional surface deformation. However, the model parameters, i.e. the thickness and depth of the sub-surface fluid reservoir, are assumed to be known a priori. Therefore, it is impossible to acquire the precise … Show more
