Seismic Ground Motion Characteristics at a University Campus with Complicated Relief

Abstract eng:
Kanazawa Hakkei Campus of Kanto Gakuin University is located in a seaside, whose size is about 250m by 750m. The greater part of the campus, whose size is about 250m by 500m, is reclaimed land and flat. We have many geological borehole data for building construction in the campus. The area of campus is small, but we have a lot of data to discuss the details of the underground structure. Compiling the materials of borehole data, we found that the campus has complicated relief of basement. We think the campus as a good experimental field for studying seismic ground motion characteristics, and we carried out seismic observation, microtremor observation and elastic wave survey. As the result of the seismic observation, the difference of JMA instrumental seismic intensity is about 1 at most. The result corresponds to the depth of the top surface of the basement at the observation site, and seismograms observed at the sites with the large intensity show long predominant periods of 0.8s, which correspond to the predominant period obtained from the microtremor observation and estimation from velocity model of the campus.
