Abstract
<p>The Fukui Earthquake wreaked havoc on the Kuzuryu River bank. In this study, we obtained microtremor observations on the Kuzuryu River bank. An extended spatial autocorrelation (eSPAC) analysis was applied to the collected array observation data to estimate the Rayleigh wave-phase velocity. The predominant period of the bank was calculated from single-point three-component observation. S-wave velocity structures were back-analyzed based on the H/V spectrum. It was confirmed that the earthquake damages on the bank were harmonized with the back-analyzed structures.</p>
