In this report, ground shaking characteristics in residential land in Kanagawa Ward, Yokohama City, Japan are evaluated based on temporary earthquake observation records. In particular, first, 33 seismographs installed with very high density at not only cutting sites but also banking sites in the residential land of interest. Seismic waveform records are then observed at the created 33 sites during some moderate earthquakes. Based on the analysis consequence of the observed seismic waveforms, finally, site amplification factors and site phase effects focused on Tokyo Bay Area were evaluated. The obtained findings will be useful in future study of strong motion prediction in the residential land of interest.
