Outline of Final Research Achievements

During the 2011 off the Pacific coast of Tohoku Earthquake and so on, a lot of serious damage occurred to embankments in Japan. In this study, to evaluate ground motions at the damage sites, temporary aftershock observation and microtremor measurement were conducted at the sites. The result indicates that the ground motions at the damage sites were similar or were not similar to those at either of the strong motions stations. The waveforms were estimated based on the site-effect substitution method or the characterized source fault model. The estimated waveforms and related discussion will be useful in future study of seismic performance of fill slope.
