Because of the large number of potential deep-seated landslides in Taiwan, for slope hazard mitigation planning, automated tools are necessary for assessing crucial landslide scarp parameters in a cost-effective manner. These landslide scarp parameters include landslide volume, shape, fracture surface depth, slope stability, and affected areas. This study proposed a method of constructing approximated three-dimensional (3D) fracture surfaces by using landslide volume and the minimal smooth surface method in which landslide volume is considered enclosed by minimal smooth surfaces and free slope surfaces. Through optimization, the minimal smooth surface can be calculated, with its circumference conforming to the observed scarp boundary. To verify applicability, we applied this method to two landslides sites in the Jiasian District of Kaohsiung City, and the preliminary assessment results indicated that this method is feasible for practical applications. In the future, a predicted 3D sliding landslide mass can be directly incorporated into slope stability analysis, landslide motion simulation, and other applications.
