Recent settlements and sinkhole openings in urban areas have caused social problems such as damage to roads and structures, fear of the public, and lossof property. Several studies have demonstrated that surface subsidence and sinkhole opening are greatly affected by rainfall and rainfall intensity in urbanareas. In this paper, we analyzed the relationship with the characteristics of recorded rainfall data using the ground subsidence database reported in majorcities. The correlations were found using sedimentation and precipitation data from 2010 to 2014. The duration and intensity of a given precipitation haveevolved to obtain an effect on ground sedimentation rate (SR). The results show that the relationship between SR and precipitation is asymptotic and canbe modeled by a hyperbolic equation. Through this study, it is possible to predict the occurrence of ground subsidence due to precipitation in advance.
