TSKにおけるP波初動部分の変位記録は,震源での継続時間が約50秒あり,約10秒間の小さな立ち上がりに続いて2個の大きなサブイペントが約20秒の間隔で発生したことを示唆する.ラ・ウニオン州のルナで約2mの高さの津波が発生したが,局地的なもので,液状化に伴って生じたとみられる. 17日に発生した最大余震(Mw6.4)は逆断層運動によるもので,主断層運動の東側のブロックが断層の北端付近を圧縮したために起きたと考えられる.","subitem_description_type":"Abstract"},{"subitem_description":"The Luzon, Philippines earthquake of July 16, 1990, with Ms=7.8, was generated by left-lateral slippage in central Luzon Island. We surveyed surface breakage over the area from Bongabon to Capintalan through Rizar, Puncan and Digdig by vehicles, and also made an aerial survey by helicopter from Dingalan Bay to north of Imugan. Ground breakage was observed and mapped for a distance of 110km along the Philippine fault system and its splay known as the Digdig fault. Maximum horizontal offset as measured on the fault at Imugan is 6m. It is one of the largest strike-slip earthquake ever recorded in the world.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"127416","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Abe, Katsuyuki"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032766","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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"阿部, 勝征"}],"nameIdentifiers":[{"nameIdentifier":"127415","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":"ji0654002.pdf","filesize":[{"value":"3.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0654002.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32766/files/ji0654002.pdf"},"version_id":"cb3c2e7d-b519-414f-966e-82969e5238ad"}]},"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":"フィリピン・ルソン島地震(1990年7月16日)の地震学的調査","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"フィリピン・ルソン島地震(1990年7月16日)の地震学的調査","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4728","4730"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"32766","relation_version_is_last":true,"title":["フィリピン・ルソン島地震(1990年7月16日)の地震学的調査"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T05:17:20.982344+00:00"}
