Slope dynamics are essential elements of the Subcarpathian landscape and are important in the interaction between humankind and the environment. The wide span of the Prahova Valley as it emerges from the mountain zone and the terraced Subcarpathian slopes has affected the orientation and type of slope dynamics, which are shaped by fragmentation and exposure conditions. The great variety of landslide types along the Subcarpathian Prahova Valley reflects the diversity of local conditions and a combination of factors that render the slopes unstable.

The GEOKA procedure is a new methodology for understanding natural processes on the Earth's surface. The analysis of the map shows a correlation with the vulnerability in the study area. Although the method is focused at an analytical level and is good for assessing small areas of vulnerability, it is difficult for identifying a pattern for vulnerability.

The GEOKA procedure identifies the changes in the curvature of the terrain surface. The authors believe the result should be verified within the context of rock mechanics, tectonics, bed slopes, and climate. The GEOKA procedure helps recognize the tendencies toward certain slope reactions in the assessment of future development and surface dynamics.
