Abstract

Microtremor small array observations were conducted at seven KiK-net earthquake observation station sites in Fukui Prefecture and dispersion curves were obtained. The S wave velocity structures in the vicinity of the surface ground were presumed by inversely analyzing the dispersion curves using genetic algorithm and the corresponding published data were examined. As a result, it was shown to have to check the published data of Izumi Site and Mikata Site, besides Eiheiji Site pointed out that there was problem before.
