%X The suspected presence of a local fault in Totogan Village, Karangsambung  Subdistrict, Kebumen Regency, is believed to play a role in controlling subsurface  geological conditions and soil dynamic characteristics in the study area. This  study aims to identify wave source direction patterns based on H/V rotate analysis  and to analyze the distribution of shear wave velocity (vs) as an indicator of the  presence of geological structural zones. The methods used were microtremors  with Horizontal to Vertical Spectral Ratio (HVSR) analysis and H/V rotate to  obtain wave source direction patterns. The processed data were then used to  construct a vs distribution model visualized in the form of a solid model and a  solid fence diagram. Additionally, supporting data analysis, including lineaments  and Fault Fracture Density (FFD), was conducted to strengthen the  interpretation of subsurface geological structures. The results of the study  indicate that the dominant direction of the wave source tends to be North–South,  with an average azimuth of N 4.6° E, as well as several other directions such as  East–West and Northeast–Southwest. The shear wave velocity (vs) values range  from 153.03 m/s to 1495.90 m/s. Zones with vs values > 1200 m/s are found in the  C–C’ section in the Northern part and again in the A–A’ section in the Southern  part with a Northeast–Southwest orientation. Additionally, zones with vs values <  500 m/s were identified, appearing in the Western part of the study area along the  B–B’ section and reappearing in the Eastern part along the E–E’ section with an  East–West orientation. The results of integrating all methods indicate the  presence of local fault zones influenced by the geological structure in the study  area.
