  • DAMAGE PREDICTION OF RIVER EMBANKMENT AND SIMULATION OF FLOOD INUNDATION DURING LARGE SCALE EARTHQUAKE IN THE FUKUI PLAIN Reviewed

    80 ( 24 )   1 - 11   2024.12

    　More details

    In this study, we predicted river embankment damage due to liquefaction on the Kuzuryu River and Hino River, based on the assumed results of a large scale earthquake caused by the eastern margin ac-tive fault zone of the Fukui Plain. In addition, the impact of the river embankment damage on flood in-undation was investigated. As a result of calculating the amount of embankment subsidence at boring points around the river embankment, the maximum amount of subsidence was 3.68 m. Furthermore, we conducted a flood analysis before and after the embankment subsidence, and compared the differences in the time series changes in the inundation area and inundation depth.

  • A Study on an Empirical Formula for Seismic Intensity Increment Based on the Parameters of Fundamental Peak Frequency of Site Amplification Effect and Microtremor H/V：Study focused on the Chugoku Region Reviewed

    43巻 ( 2号 )   253 - 271   2024.8

    　More details

    In this paper, we proposed a seismic intensity increment evaluation formula using the parameters of the fundamental peak of microtremor H/V in order to accurately evaluate seismic intensity increments even at locations where the exact average S-wave velocity structure is unknown. First, we derived an approximate expression that simplified the relationship between the earthquake ground motion spectrum and the seismic intensity increment. Calculated values and approximate values of seismic intensity increments were estimated for various earthquake magnitudes and pseudo site amplification effects, and it was shown that these values correspond well. In addition, it was shown that the seismic intensity increment can be evaluated to some extent by considering only the fundamental peak of the site amplification effects for the seismic stations targeted in this study. Next, seismic intensity increments and site amplification effects were evaluated for seismic stations in the Chugoku region and other areas. We also found an empirical formula for evaluating seismic intensity increments using the parameters of the fundamental peak of site amplification effects, and showed that seismic intensity increments can be evaluated with good accuracy. Finally, we obtained an empirical seismic intensity incremental evaluation formula using the parameters of the fundamental peak of microtremor H/V. As a result, it was clarified that the seismic intensity increment can be evaluated with good accuracy, although the prediction accuracy is lower than when using the site amplification effects.
