The V_S30 of 89 stations in Republic of Korea are predicted using semi-empirical relationship between natural frequency (f_p) selected from horizontal-to-vertical spectral ratio (HVSR) and time averaged shear wave velocity down to 30 m depth (V_S30). The installation of seismic stations has been accelerated in Republic of Korea after two damaging earthquakes at 2016–2017, but the majority of stations do not have geophysical investigation yet, and even for a few stations the investigation is prohibited due to deforestation issue and civil complaints. The objective of this study is to predict V_S30 for stations without investigation using f_p to V_S30 relationship. The HVSR of 48 stations with measured V_S30 are analyzed to find appropriate f_p selection and the best-fitted model. We found that the f_p-V_S30 relationship is weak if the peak is not distinct and HVSR amplitude is low, and the model developed for the stable continent region fits the best.

大韩民国89个台站的V _{S 30}是使用从水平与垂直频谱比（HVSR）中选择的自然频率（f _p）与低至30 m深度的时间平均剪切波速度（V）之间的半经验关系预测的_{S 30}）。在2016-2017年发生两次破坏性地震后，大韩民国加快了地震台的安装，但大多数地震台尚未进行地球物理调查，即使是少数地震台，由于森林砍伐和民事投诉也被禁止进行调查。 。这项研究的目的是在不进行调查的情况下使用以下方法预测站点的V _{S 30：}f _p与V _{S 30的}关系。分析了48个测得的V _{S 30}站的HVSR，以找到合适的f _p选择和最佳拟合模型。我们发现，如果峰不明显且HVSR振幅低，则f _p - V _{S 30}关系较弱，并且为稳定大陆地区开发的模型最合适。
