Abstract
A method of estimating earthquake ground motion using microtremor horizontal to vertical (H/V) Fourier spectral ratio is presented. Inthis method, an earthquake ground motion is estimated from the earthquake ground motionrecorded in thenearby observation site by usingthe correction factors which consist of the microtremor H/V spectralratio of the both sites (the reference site and estimation site), the path effect factor of waves β, and the site factor ofvertical ground motions γ. By using the observed microtremor records andearthquake ground motions in the Miyazaki Prefecture, the presented estimation method is examined. And also the error of estimation of Fourierspectral amplitude of earthquake horizontal ground motion is discussed.
