It is common knowledge that snowmelt, excessive precipitation, naturally occurring or man-made faulty applications, and static loading conditions can weaken slope stability, which can result in numerous fatalities and property damage. Then again, it is referred to that a few disastrous earthquakes, for example, 1999 Izmit (Mw=7.1), 2023 Pazarcık (Mw=7.7) and Elbistan (Mw=7.6) that happened because of the way that our country is situated in the earthquake belt trigger the slope stability. Within this scope, the mass moves that might happen on the slopes because of the earthquake might cause loss of life and property as well as prevention of road transport. In light of the earthquake, it is critical to guarantee that intercity highways will continue to be serviceable. In this paper, a 3D point cloud was made utilizing photogrammetrically high-resolution aerial photographs and a primer examination of a selected slope system was performed in the Zigana region of the Gümüşhane-Trabzon highway (the previous Zigana Tunnel 5 km). The noise of the point cloud made by utilizing morphological and statistical sorting filters is excluded. Within the relevant point cloud, a section was created from the 3D surface of a region. By using this section, slope stability analysis were implemented for static and dynamic loading situations of the slope by taking into account some foundation rock parameters that are thought to represent the region. In this study, the effect of earthquake induced dynamic analyses on stability were investigated comparatively. As a result of the selected parameters, it is observed that the road slopes that appear to be stable can become unstable especially with the earthquake effect.
