Hypocenter determination using station corrections based on the sediment thicknesses significantly reduces scattering of hypocenter distribution, which gives clear images of the subducting Pacific plate and earthquake faults. The MCS records showing detailed sediment structure summarized in this report are also useful for estimation of ground properties and so on.", "subitem_description_language": "ja", "subitem_description_type": "Abstract"}]}, "item_10002_description_6": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "付録　マルチチャネル反射地震探査断面図 Appendix Multi-channel seismic-reflection (MCS) profiles", "subitem_description_language": "ja", "subitem_description_type": "Other"}]}, "item_10002_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.24732/NIED.00003448", "subitem_identifier_reg_type": "JaLC"}]}, "item_10002_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "防災科学技術研究所", "subitem_publisher_language": "ja"}]}, "item_10002_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1347-748X", "subitem_source_identifier_type": "EISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "西澤 あずさ", "creatorNameLang": "ja"}, {"creatorName": "ニシザワ アズサ", "creatorNameLang": "ja-Kana"}], "familyNames": [{"familyName": "西澤", "familyNameLang": "ja"}, {"familyName": "ニシザワ", "familyNameLang": "ja-Kana"}], "givenNames": [{"givenName": "あずさ", "givenNameLang": "ja"}, {"givenName": "アズサ", "givenNameLang": "ja-Kana"}]}, {"creatorNames": [{"creatorName": "植平 賢司", "creatorNameLang": "ja"}, {"creatorName": "ウエヒラ ケンジ", "creatorNameLang": "ja-Kana"}], "familyNames": [{"familyName": "植平", "familyNameLang": "ja"}, {"familyName": "ウエヒラ", "familyNameLang": "ja-Kana"}], "givenNames": [{"givenName": "賢司", "givenNameLang": "ja"}, {"givenName": "ケンジ", "givenNameLang": "ja-Kana"}], "nameIdentifiers": [{"nameIdentifier": "9000347104474", "nameIdentifierScheme": "CiNii"}]}, {"creatorNames": [{"creatorName": "望月 将志", "creatorNameLang": "ja"}, {"creatorName": "モチヅキ マサシ", "creatorNameLang": "ja-Kana"}], "familyNames": [{"familyName": "望月", "familyNameLang": "ja"}, {"familyName": "モチヅキ", "familyNameLang": "ja-Kana"}], "givenNames": [{"givenName": "将志", "givenNameLang": "ja"}, {"givenName": "マサシ", "givenNameLang": "ja-Kana"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "download_preview_message": "", "file_order": 0, "filename": "3448_22_1.pdf", "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "application/pdf", "size": 0, "url": {"label": "n471.pdf", "url": "https://nied-repo.bosai.go.jp/record/2291/files/3448_22_1.pdf"}, "version_id": "c2a12e28-5eb5-45f4-8a3c-adae46612413"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "S-net,マルチチャネル反射法地震探査,堆積層厚,観測点補正,震源分布", "subitem_subject_language": "ja", "subitem_subject_scheme": "Other"}, {"subitem_subject": "S-net,Multi-channel Seismic Profile,Sediment Thickness,Station Correction,Hypocenter Distribution", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "マルチチャネル反射法地震探査から推定されたS-net 観測点下の堆積層分布および堆積層補正を用いた震源決定例", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "マルチチャネル反射法地震探査から推定されたS-net 観測点下の堆積層分布および堆積層補正を用いた震源決定例", "subitem_title_language": "ja"}, {"subitem_title": "Sediment Distribution Beneath S-net Stations Derived from Multi-channel Seismic Reflection Profiles and Hypocenter Determination Using the Sediment Correction", "subitem_title_language": "en"}]}, "item_type_id": "10002", "owner": "6", "path": ["1000"], "permalink_uri": "https://doi.org/10.24732/NIED.00003448", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2022-03-01"}, "publish_date": "2022-03-01", "publish_status": "0", "recid": "2291", "relation": {}, "relation_version_is_last": true, "title": ["マルチチャネル反射法地震探査から推定されたS-net 観測点下の堆積層分布および堆積層補正を用いた震源決定例"], "weko_shared_id": -1}
