A circular patch with velocity-weakening frictional property is embedded in the fault, while velocity-strengthening frictional property is assumed in the other region. Simulation results indicate that slip events repeatedly occur at the velocity-weakening patch and slower slip propagates outwards in the velocity-strengthening region. The characteristics of simulated slip on the fault patch are controlled by the ratio of the patch radius r to the critical fault radius rc, which is the critical nucleation patch radius for unstable slip, and is defined as a function of frictional constitutive parameters. When r≫rc, ordinary earthquakes with high slip rates repeatedly occur at the fault patch and postseismic aseismic slip follows on the fault outside the patch. When r～rc, episodic aseismic slip events (silent earthquakes) occur. The rise time of the episodic event increases with a decrease in r/rc. When r≪rc, stable sliding occurs. These results indicate that the rc value can be estimated from geodetically determined values of the fault radius and the source duration of an episodic aseismic slip event.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"125707","nameIdentifierScheme":"WEKO"}],"names":[{"name":"加藤, 尚之"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032559","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":"Earthquake Research Institute, University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kato, Naoyuki"}],"nameIdentifiers":[{"nameIdentifier":"125706","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":"IHO78203.pdf","filesize":[{"value":"1.1MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"IHO78203.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32559/files/IHO78203.pdf"},"version_id":"17e808a8-61f6-4cbf-93d1-da73611f2afa"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"episodic aseismic slip event","subitem_subject_scheme":"Other"},{"subitem_subject":"repeating earthquake","subitem_subject_scheme":"Other"},{"subitem_subject":"postseismic sliding","subitem_subject_scheme":"Other"},{"subitem_subject":"friction","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":"Repeating Slip Events at a Circular Asperity : Numerical Simulation with a Rate- and State-Dependent Friction Law","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Repeating Slip Events at a Circular Asperity : Numerical Simulation with a Rate- and State-Dependent Friction Law","subitem_title_language":"en"}]},"item_type_id":"4","owner":"1","path":["4625","4626"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-04-23"},"publish_date":"2007-04-23","publish_status":"0","recid":"32559","relation_version_is_last":true,"title":["Repeating Slip Events at a Circular Asperity : Numerical Simulation with a Rate- and State-Dependent Friction Law"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T05:29:37.260616+00:00"}
