000011941 520__ $$2eng$$aThe objective of this study is to identify the damping property Q (quality factor) of subsurface ground by Sweeping Method, which was proposed by the authors, using the vertical array records of earthquake ground motions. National Research Institute for Earth Science and Disaster Prevention (NIED) deploys digital strong-motion seismographs (KiK-net) all over the country in Japan, which provide vertical array records of ground motions. The total number of observation sites is nearly 700. Data observed by KiK-net can be downloaded on the website, which can be used for the identification of such parameters of subsurface laminated layers as shear wave velocity and quality factor. In this study, using KiK-net data, the frequency-dependent characteristics of the quality factor is extracted.
