Characteristics of the shape obtained by this study are almost the same as the previously proposed models based on seismic data of Nagoya University and NIED, respectively, for the region to the east of Ise Bay. That is, in the area to the west of Suruga Bay, the slab deepens to the west, while it inclines to the north around Lake Hamana, and a valley-like configuration is observed near Omaezaki Point and its north-west region. The deepest portion of the Tokai slab exists beneath southeastern Gifu Prefecture. We calculated the gradient vector of the subducting slab at each point on the surface using the shape of the model. By comparing the gradient vector field with the seismicity in the slab, we found a coincidence between the regions of high seismicity and the zones where the gradient vector changes greatly. This coincidence suggests the relevance between the bending of the Philippine Sea plate and the occurrence of earthquakes in the slab. On the basis of the observation we propose that one of the main causes generating seismogenic stress in the slab in the Tokai region is conformation of the Philippine Sea plate to the shape of the subducted slab in the course of plate motion.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"126693","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Harada, Satoshi"}]},{"nameIdentifiers":[{"nameIdentifier":"126694","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yoshida, Akio"}]},{"nameIdentifiers":[{"nameIdentifier":"126695","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Aketagawa, Tamotsu"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032669","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":"気象研究所地震火山研究部"},{"subitem_text_value":"気象庁地震火山部"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"原田, 智史"}],"nameIdentifiers":[{"nameIdentifier":"126690","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉田, 明夫"}],"nameIdentifiers":[{"nameIdentifier":"126691","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"明田川, 保"}],"nameIdentifiers":[{"nameIdentifier":"126692","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":"ji0733003.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0733003.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32669/files/ji0733003.pdf"},"version_id":"12cc5703-f6ab-45be-ab02-4c9489b109d7"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Tokai region","subitem_subject_scheme":"Other"},{"subitem_subject":"Philippine Sea slab","subitem_subject_scheme":"Other"},{"subitem_subject":"gradient vector","subitem_subject_scheme":"Other"},{"subitem_subject":"seismic activity","subitem_subject_scheme":"Other"},{"subitem_subject":"seismogenic stress","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":"東海地域に沈み込んだフィリピン海スラブの形状と地震活動","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"東海地域に沈み込んだフィリピン海スラブの形状と地震活動","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4666","4668"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"32669","relation_version_is_last":true,"title":["東海地域に沈み込んだフィリピン海スラブの形状と地震活動"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T05:17:18.678079+00:00"}
