Landslide susceptibility of Makkah Al-Mukarramah has been assessed by collecting microtremor measurements at 277 sites covering the whole area. These data were then processed and analyzed using the horizontal–vertical spectral ratio (HVSR) method to obtain the resonance frequency and H/V amplification factor. The results display that the predominant frequency values range between 0.26 and 17.27 Hz, and the amplification factor varies from 0.87 to 14.68. Then, 34 sites were selected to assess the frequency, amplitude and azimuthal site response where frequency ranges from 0.26 to 13.67 Hz while amplitude varies from 2.0 to 12.2. Moreover, the site response direction was parallel to the landslide directional response in the sliding areas which indicates that the site response direction followed the landslide direction. The results of this study have been approved practically at several sites through field measurements at some of recent landslide occurrence locations in Makkah urban area. These results signifying that microtremor measurements are effective technique in locating the sites suffering landslides, which, in turn, reduce their hazardous impact on either human-life and their beings. Therefore, it is highly recommended to apply this approach in places prone to landslides in southwestern Saudi Arabia.

通过收集覆盖整个地区的277个地点的微震测量数据，对Makkah Al-Mukarramah的滑坡敏感性进行了评估。然后使用水平-垂直光谱比（HVSR）方法对这些数据进行处理和分析，以获得共振频率和H / V放大系数。结果表明，主要频率值在0.26至17.27 Hz之间，并且放大系数在0.87至14.68之间变化。然后，选择了34个站点来评估频率，幅度和方位站点响应，其中频率范围从0.26到13.67 Hz，而幅度从2.0到12.2。此外，在滑动区域中，场地响应方向与滑坡方向响应平行，这表明场地响应方向遵循滑坡方向。通过对麦加市区最近的一些滑坡发生地点的现场测量，该研究的结果已在多个地点得到了实际认可。这些结果表明，微震测量是定位遭受滑坡的地点的有效技术，从而减少了滑坡对人类和人类的有害影响。因此，强烈建议在沙特阿拉伯西南部容易发生山体滑坡的地方采用这种方法。
