Time series cumulative vertical deformation maps from 2007/01/18 to 2011/03/16 over the study area. The reference image for 2007/01/18 is omitted. Green circle represents the API No. 38931913 wastewater disposal well. Black circle represents the deformation center. Yellow dash line shows the surface profile of the total vertical deformation plotted in Fig. 5(d).
