Seismic amplification
WebDec 1, 2024 · The seismic response of the slope, geological setting, geotechnical character were considered as the main factors accounting for landslides triggered by the Wenchuan earthquake. ... The strong amplification particularly the AAF-X at the upper portion of the slope, presents a good explanation for large rock block thrown occurred at slope crest ... WebAug 1, 2024 · The amplification factor can be very roughly estimated through ground motion prediction equations [25,26], quite roughly from studies at the national scale (e.g. Ref. [27]), and more accurately from seismic microzonation studies at the city scale [28]. A rigorous approach would require site response analyses under numerous input motions.
