The total number of the events, as reported in the Earthquake Data Report of the U.S. Coast and Geodetic Survey was 260. The Galapagos Islands are one of the volcanically most active regions in the world. For example, there are found: Volcano La Cumbre in Fernandina Island and Volcano Wolf, Volcano Darwin and Volcano Alcedo in Isabela Island in Galapagos Islands. An eruption phenomenon was reported just before the present earthquake activity at Fernandina Island, by the Center for Short Lived Phenomena of the Smithsonian Institution. The activity continued from 15hOOm to 23hOOm (U.T.) on May 21, on a small-scale. But there was an intensive eruption at 10h18m on June 18. The main visible result of the activity was the collapse of the caldera floor, the southeast part of which dropped 300m. The volume of collapse was 1～2km3. The activity area of the earthquakes swarm includes the region of Fernandina Island and Isabela Island. The total number of the larger earthquakes of the swarm with magnitude 5.0 or more, which occurred through the whole period, amounted to 16. We report the results of an investigation, using the data published by the USCGS as well as the seismograms of long-period type obtained at the Galapagos Seismological Station of WWSSS, and discuss in this paper.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"130015","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Iwata, Takayuki"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000033301","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":"岩田, 孝行"}],"nameIdentifiers":[{"nameIdentifier":"130014","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":"ji0485014.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0485014.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/33301/files/ji0485014.pdf"},"version_id":"0587fdb8-778c-4a79-88d5-75e6225f1423"}]},"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":"49. 1968年6月のGalapagos諸島の群発地震について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"49. 1968年6月のGalapagos諸島の群発地震について","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4889","4890"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"33301","relation_version_is_last":true,"title":["49. 1968年6月のGalapagos諸島の群発地震について"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:08:59.748752+00:00"}
