| Abstract;A dense array observation for seismic ground motion as weak as JMA intensity 1 or less is performed in the campus of Building Research Institute where the ground condition is classified shallow Artificial Fill that is commonly found in residential area, in order to grasp the lateral variation of seismic ground motion in the frequency range from 2Hz to 10Hz. The coherence analyses show that points on the ground surface separated more than around 15m each other move almost independently at such high frequency as 5Hz, and around 5m at 10Hz, if threshold value is taken 0.8.
