InSAR and DInSAR have contributed significantly to improved hydrogeologic information and advances in hydrogeology since the late 1990s. Most of the hydrogeologic applications were in the topic areas of land subsidence, hydrogeologic framework, landslides and soil moisture. The annual numbers of relevant citations from refined bibliographic searches show significant and episodic growth during 1998-2013, with generally twice as many annual citations during 2008-13 than during 2003-07. Applications in land subsidence research were predominant each year. The searches revealed a) articles and conference papers constituted 98% of citations; b) country affiliations for authors were broadly distributed but most of the citations were from authors in Europe (~30%), North America (~29%), and Asia (~18%); and c) the principal subject areas were in the Earth and Planetary Sciences, Engineering, and Environmental Science which constituted 69% of the citations, with Computer Science contributing 13%.
