Abstract
The eighth meeting of the Microtremor Research Camp (MRC) was held in Ohno City, Fukui Prefecture from September 30th to October 2nd in 2016, and MRC carried out microtremor measurement in Katsuyama Basin that is constituted with deposits of Kuzuryu River. This measurement consists of 19 sites of micro-array measurement (MRM) and 67 sites of single-point measurement (SPM). This paper reports the outline of this measurement and eventually presents the distribution of predominant frequencies (DPF) in the basin obtained through the analysis of horizontal-to-vertical ratio (HVR) at SPM sites. As the result, the large differences of DPF and PSV (peak spectral values) in between Quaternary terrace deposits and alluvial deposits are clarified.
