Abstract

Site amplification is important in ground motion prediction. It describes the effect of soil sites on ground motions. The quarter-wavelength approximation for computing site amplification has been developed for several decades. It is validated by the data from the main shock of 2011 Tohoku-oki Earthquake, recorded by KiK-net. A part of the site amplification factors obtained by quarter-wavelength approximation method are less than the actual amplification factors. The most ratios of the real amplification are smaller than 10, can more accurately reflect the true site amplification.
