The earthquake in Cianjur occurred on Monday, November 21, 2022. The epicenter was in Cugenang Subdistrict, Cianjur District, West Java Province. Cianjur is an area that is susceptible to landslides, which can be triggered by high rainfall and earthquake shocks. The Cianjur earthquake caused collateral hazard landslides that occurred in several locations. Based on the static and pseudo-static analysis, the pseudo-static analysis will provide information on how much the slope safety number decreases when earthquake loads are applied. This study aims (1) to calculate the safety factor value (SF) of slopes under static and pseudo-static conditions to assess the stability of the natural slope and (2) to determine the influence of geological characteristics and the Cianjur earthquake on slope stability analysis in landslides in Cianjur and its surroundings. Slope stability analysis was carried out using static and pseudo-static methods. This research result shows that the condition of the slopes of the study area before the earthquake occurred was in safe condition. The condition of the slopes in the study area experienced a decrease in the safety value of the slope from natural conditions to increased loads or earthquake shaking.
