%X Gayamharjo village Prambanan subdistrict Sleman regency has steep hills  morphology. In the rainy season, the material on the slope is easier to move down  and causing landslides. To reduce the risk, microtremor measurements were  conducted to map landslide prone area in Gayamharjo village.  Microtremor acquisition were performed at 1600 m2. The microtremor  data was taken on 25 observation points with 100 meters spacing as primary.  Selected microtremor data were processed by Horizontal to Vertical Spectral  Ratio (HVSR) method to get dominant frequency and site amplification value.  Both of parameters are used to calculate the quantitative parameters, such as  layer thickness weathered, seismic vulnerability index and the value of shear  strain. Shear strain value represents deformation on the surface, such as cracks,  settlement, and landslides.  From HVSR process, dominant frequency and site amplification were  obtained. Dominant frequency varies at 1,21 to 14,45 Hz and site amplification  varies at 0,73 to 29,79. Shear strain that obtained empirically from the frequency  and amplification varies at 6,74 x 103 to 1,67 x 101. The highest value of shear  strain in this AD18 observation area. The highest value of shear strain in this  study shows ground settlement phenomenon, and the lowest shows cracks  phenomenon. Finally, Shear Strain and slope class were multiplied to obtain  landslide potential.
