Landslides are among the most recurrent natural hazards in Indonesia, particularly within the Special Region of Yogyakarta, where Bantul Regency is classified as a high-risk zone.

This research aimed to characterize the subsurface lithology and identify potential slip surface in this area using the electrical resistivity method with Wenner array configuration.
