| | Abstract | | A surface-wave method and micro-tremor array measurements have been carried out at Central Anamizu, Ishikawa Prefecture in order to obtain near surface S-wave velocity model of the site. Many houses were collapsed or severely damaged by the 2007 Noto-hanto Earthquake at Central Anamizu. Collapsed or damaged houses were concentrated around the K-NET Anamizu strong ground motion observation station. The investigation result shows that S-wave velocity down to the depth of 20m has strong heterogeneity at the site. Low velocity layer, in which S-wave velocity is 60m/s, beneath the K-NET Anamizu disappears at the other side of the park only 50m away from the K-NET. |
