Abstract: Karst sinkhole hazards have the characteristics of wide distributions, frequent occurrences, hard to predict, many affecting factors; high variation and complication as well as high cost for the remediation after collapse. This paper evaluates aspects that cause the karst sinkholes and possible major factors that affecting the collapse are determined in order to provide predictions for the sinkhole risk potentials. The evaluation method utilizes the theory of analytic hierarchy process so that the risk potentials can be reliably evaluated in both quantitatively and qualitatively.  The five (5) subsidence factors, karst conditions, hydrological conditions, topographical conditions, cover thickness as well as human activities, are analyzed using hierarchy process. Their contribution to the collapse are weighted and programmed in excel spreadsheet. The regional subsidence potential is then provided.
