| | Abstract | | Distribution of active faults is essential information for evaluating the location and the length of the source faults of inland crustal earthquakes. We have examined an applicability of a method to investigate passing positions of active faults, especially in the gaps and the steps, based on the peak frequencies of the horizontal-to-vertical spectral ratios (H/V spectra). In this research, we conducted microtremor measurements near a trench site of the Kamishiro fault. In this article, we discuss a correspondence between the spatial variation of the peak frequencies of the H/V spectra of microtremors and the distribution of the shallow geological structures. |
