A Slope failure of the embankment was observed at the Tomei Expressway around Makinohara Service Area in the earthquake of Suruga Bay in 2009. It is important to estimate the seismic ground motion of the site for the clarification of failure mechanism. In this study, microtremor measurements were executed around the site and other embankments along express way (Yoshida I.C.~Sagara-Makinohara I.C.~Kikugawa I.C.). And, the ground shaking characteristics around the site of slope failure was evaluated.
