Keywords:H/V spectral ratio, R/V spectral ratio, three-dimensional velocity structure model

S-wave velocity strucrure of Oita prefecture is checked using H/V and R/V spectral ratio analyzed with strong motion data observed with strong motion network operated by Oita Prefecture. See detail in our Japanese abstract.
