In this study, changes of seismic motion in a developed residential site in Sendai-City Japan before and after the Great East Japan Earthquake are mentioned. That is because the seismic motion character of fill ground may change before and after this large earthquake because of the fill ground damages. We observed earthquake records at a residential development which has numerous zones of cut and fill from the year 2007. The instrumental seismic intensity and the Fourier spectral ratio of acceleration were arranged using 33 earthquake records. As a result, at the cut area, observed seismic intensity was smaller than the fill area, on the whole. After the Great East Japan Earthquake, at almost all sites, the difference of instrumental seismic intensity against a base site became larger and at some site, the spectral ratio became larger at frequency of 4.5Hz to 6.0Hz than that of before the earthquake.
