Estimated horizontal velocity vectors in ITRF2000 are found to be in the range of 29～35mm/yr with an uncertainty level in the order of 1～2mm/yr (95％ confidence level). Then, estimated velocities are converted into a kinematic reference frame (Prawirodirdjo and Bock, 2004) to discuss crustal deformation relative to the Eurasian plate. Least-Squares prediction (LSP) technique is employed to segregate signal and noise from velocity vectors. Estimated signals are used to reconstruct strains, dilatations, maximum shear strains, and principal axes of strains. Strains obtained might portray active tectonic environments in the region under study. (1) Dilatational strains indicate that the region under study is mainly divided into two areas : the western part around the Gulf of Suez where extensional strain is predominant, and the eastern part around the Gulf of Aqaba where compressional strains prevail. (2) Maximum shear strain is mostly accommodated at the Gulf of Suez and Gulf of Aqaba. Distribution of seismicity shows high consistency with high shear strain areas. The estimated dilatation strain rate and the maximum shear strain rate are both 0.25 Micro-strain/yr on average. (3) Principal axes of the strains indicate that an extensional force is acting along the Gulf of Suez in the NE-SW direction. Moreover, the principal axes of strains show a good correlation with the SHmax directions obtained from earthquake focal mechanisms and borehole breakouts.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"125311","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ガマル, エルフィキ"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032530","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":"51.1","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":"Construction Eng. & Utilities Department, Faculty of Eng., Zagazig University, Zagazig, Egypt"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Gamal, El-Fiky"}],"nameIdentifiers":[{"nameIdentifier":"125310","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":"IHO80202.pdf","filesize":[{"value":"6.3MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"IHO80202.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32530/files/IHO80202.pdf"},"version_id":"05ae8afe-6c5f-4ab7-904f-dcc761169e47"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Sinai Peninsula","subitem_subject_scheme":"Other"},{"subitem_subject":"Gulf of Suez","subitem_subject_scheme":"Other"},{"subitem_subject":"Gulf of Aqaba","subitem_subject_scheme":"Other"},{"subitem_subject":"GPS measurements","subitem_subject_scheme":"Other"},{"subitem_subject":"crustal strains","subitem_subject_scheme":"Other"},{"subitem_subject":"least-squares prediction","subitem_subject_scheme":"Other"}]},"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":"GPS-derived Velocity and Crustal Strain Field in the Suez-Sinai Area, Egypt","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"GPS-derived Velocity and Crustal Strain Field in the Suez-Sinai Area, Egypt","subitem_title_language":"en"}]},"item_type_id":"4","owner":"1","path":["4609","4610"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-04-23"},"publish_date":"2007-04-23","publish_status":"0","recid":"32530","relation_version_is_last":true,"title":["GPS-derived Velocity and Crustal Strain Field in the Suez-Sinai Area, Egypt"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T05:29:37.207851+00:00"}
