The seismic waves generated by this blast were recorded at about 10 observatories under the Japan Meteorological Agency. Although the recorded amplitude was rather small and the onset of initial motion was not clear except at Matsushiro, the attempt to determine the quantities concerning hypocentre was done by the method of least squares. The results which are given in Table 2 confirmed my previous conclusions. In the present calculation the position of epicentre was determined within 0.1 degree, the velocity was determined rather well, but the determination of the origin time is not good. Giving weight to the observation at Matsushiro we could obtain better results, especially with respect to the origin time. The velocity of <S wave was also obtained as 3.34km/sec.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"132187","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Asano, Shuzo"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000033891","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":"浅野, 周三"}],"nameIdentifiers":[{"nameIdentifier":"132186","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":"2017-06-27"}],"displaytype":"detail","filename":"ji0372008.pdf","filesize":[{"value":"657.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0372008.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/33891/files/ji0372008.pdf"},"version_id":"4559607a-7e18-4967-ad9b-cb5fefba8010"}]},"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":"震源決定の精度について(第3報)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"震源決定の精度について(第3報)","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["5013","5014"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"33891","relation_version_is_last":true,"title":["震源決定の精度について(第3報)"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:58:14.422100+00:00"}
