The average value of ASR for the period 0.1 to 0.5 seconds is used as the average spectral ratio intensity (ASRI), which is an index of the seismic amplification effect at the observation point. A clear negative correlation was observed between ASRI and average S-wave velocity to a depth of 30m (AVS30). On the other hand, a weak positive correlation was found between ASRI and the curvature of the topographic index. In some cases, the influence of topography on the seismic amplification was suggested. However, there was a group of mountain slopes whose ASR did not differ significantly from that of non-mountain slopes, suggesting that mountain slopes have limited seismic amplification.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "公益社団法人 日本地すべり学会", "subitem_publisher_language": "ja"}, {"subitem_publisher": "The Japan Landslide Society", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.3313/jls.60.62"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1882-0034", "subitem_source_identifier_type": "EISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "飯田 智之", "creatorNameLang": "ja"}, {"creatorName": "IIDA Tomoyuki", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "川邉 洋", "creatorNameLang": "ja"}, {"creatorName": "KAWABE Hiroshi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "陳 麒文", "creatorNameLang": "ja"}, {"creatorName": "CHEN Chi-Wen", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "山田 隆二", "creatorNameLang": "ja"}, {"creatorName": "YAMADA Ryuj", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "佐藤 昌人", "creatorNameLang": "ja"}, {"creatorName": "SATO Masato", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_title": "KiK-netの地表/地中フーリエスペクトル比からみた山地斜面の地震波増幅特性―地震地すべりに影響する揺れやすさの基礎研究―", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "KiK-netの地表/地中フーリエスペクトル比からみた山地斜面の地震波増幅特性―地震地すべりに影響する揺れやすさの基礎研究―", "subitem_title_language": "ja"}, {"subitem_title": "Seismic wave amplification characteristics of mountainous areas based on surface to subsurface spectral ratios of KiK-net seismograms－Fundamental study on coseismic landslides susceptibility－", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "7", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/6362", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-09-20"}, "publish_date": "2023-09-20", "publish_status": "0", "recid": "6362", "relation": {}, "relation_version_is_last": true, "title": ["KiK-netの地表/地中フーリエスペクトル比からみた山地斜面の地震波増幅特性―地震地すべりに影響する揺れやすさの基礎研究―"], "weko_shared_id": -1}
