The model consists of a steep-sided, circular island which rises from the top of a circular sill of larger radius. The center of the island is placed off-center of the sill by Δr distance. The results are : (1) As the asymmetry becomes pronounced, the region of higher amplitude response shifts to the direction of the broader shelf. (2) The transfer function in the case of an asymmetric island can be estimated roughly by using the solution of a symmetric island model whose width of the round shelf coincides with the broadest width of the shelf in the asymmetric model. In water level observations at four stations around Oshima Island, a spectrum peak of period approximately 8 minutes could often be detected at the westernmost station. To understand this feature, numerical calculations were made both for the realistic Oshima-Island model (with actual bathymetry), and for the Island-Shelf model (which roughly approximated the topography of the Oshima Island area). And it was found that the oscillations of the observed peak period of 8 min. corresponded to a (1, 0) mode of edge wave. This mode is modified by the asymmetry of the insular shelf and forms a standing wave pattern with a node extending in the southwesterly direction vis-a-vis Oshima Island.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"128180","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hashimoto, Michiaki"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032876","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学地震研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162258","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00408972","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"453","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Earthquake Research Institute, University of Tokyo"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"地震研究所"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"橋本, 道明"}],"nameIdentifiers":[{"nameIdentifier":"128179","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-26"}],"displaytype":"detail","filename":"ji0611002.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0611002.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32876/files/ji0611002.pdf"},"version_id":"1e63dc2d-75de-4813-a8dd-495d93b6ba3d"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"The Effect of Asymmetric Insular Shelf in Trapping Long Gravity Waves around an Island","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The Effect of Asymmetric Insular Shelf in Trapping Long Gravity Waves around an Island","subitem_title_language":"en"}]},"item_type_id":"4","owner":"1","path":["4775","4776"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"32876","relation_version_is_last":true,"title":["The Effect of Asymmetric Insular Shelf in Trapping Long Gravity Waves around an Island"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T05:17:29.087547+00:00"}
