%X Kulon Progo is one of D.I Yogyakarta's regencies which has a high potential for landslides. One of the villages that presents a high level of risk for land displacement are the villages of Jeruk and Kemiriombo, the village of Gerbosari. The purpose of this study was to analyze the risk of ground movement using microseismic parameters, that is, Predominant Frequency (fo), Amplification Factor (Ao), Seismic Vulnerability Index Value (Kg), Azimuth Ao and equipped with a slope in the village of Gerbosari. This study uses the HVSR (Horizontal to Vertical Spectral Ratio) method to produce an H/V curve that produces the parameters Ao and fo which are then used to calculate the value of the Seismic Vulnerability Index (Kg). The results showed that the distribution of the Predominant frequency values varied from 5,1 to 28,9 Hz, Amplification Factor Value (Ao) from 2.1 to 14.13 and the value of the seismic vulnerability index 0,2 to 9,8. The condition of the slopes of the citrus and kemiriombo hamlets also varies from low slope (8%) to steep slopes (> 46%) with residential areas on moderate to steep slopes. The results of the analysis of the level of earth movement risk show that the South-Southeast area has a high level of risk and the Northwest-Northeast Area, Partly Southeast towards Southeast. The Northeast has a moderate level of risk, while the South-South-West area is towards West-Northwest and the center of the study area shows a low level of risk. The analysis of the rose diagram shows the orientation of the wave magnification showing Mostly from North North East to North East direction. South Southwest, northwest to Southeast and North Northwest to South Southeast.
