Abstract

A soil database of the damaged area by The Mid Niigata prefecture Earthquake in 2004 was established based on collected 746 boring data.
The distribution of amplification factor was computed by using soil properties of the boring data.
In order to investigate the relationship of the strong ground motion and the pipeline damage, the distribution of surface strong motion was evaluated from the observation records taking account of amplification factors of shallow soil deposits.
