Mechanism of deformation around northern Hejin, China, observed by InSAR

Interferometric synthetic aperture radar (InSAR) images reveal deformation around northern Hejin, Shanxi Province.The small baseline subset (SBAS) approach for InSAR-derived deformation indicates that the observed deformation pattern can be characterized by the sum of two phenomena: background subsidence from December 2003 to February 2009 with a cumulative displacement of approximately 5 cm and uplift from February 2009 to November 2010 with a cumulative displacement of approximately 2.5 cm.Deformation modeling indicates that the local deformation was caused by the closing and opening of a sill beneath northern Hejin.The modeled sill which is approximately 5 km long, 2 km wide, is centered at 1.5 km depth.The deformation was caused by the withdrawal and influx of subsurface water.
