STRONG MOTION ESTIMATION AT THE EMBANKMENT OF THE TOMEI EXPRESSWAY DAMAGED BY THE 2009 SURUGA BAY EARTHQUAKE BASED ON EMPIRICAL SITE AMPLIFICATION AND PHASE EFFECTS

Abstract

  Slope failure occurred in an embankment of the Tomei expressway during the 2009 Suruga Bay Earthquake. Therefore, evaluation at this site with high resolution of the strong seismic motion is very important to clarify the landslide mechanism. In this study, seismic waveform at this site was estimated based on empirical site amplification and phase effects. The estimated seismic waveform is consistent with the behavior of tombstone nearby the site.
