On a profile of 58km-length, 6 shots and 77 temporary observational sites were arranged by many universities and institutes. This profile was located 10 km east-ward of the profile of the experiments in 1983. Between the two profiles is the Itoigawa-Shizuoka Tectonic Line. One of our aims is to show the difference in the crustal structure related to this tectonic line. Fortunately, the weather conditions were good for the experiment and we obtained high quality data. Compared with the case of the 1983 experiment, the intercept time of the refracted waves from the 6.0 km/s layer was smaller indicating the shallow basement. Some observed later phases were regarded as the reflected waves from the deeper crust. Others might be waves propagated from the eastern side of the tectonic line.","subitem_description_type":"Abstract"},{"subitem_description":"1987年10月に山梨県早川町から静岡県静岡市にわたる測線長約58kmで人工地震による地殻構造探査が行われた.観測には全国の大学や関係機関が参加し,観測点は全部で77点になった.爆破点は6箇所で,その薬量は300～500kgである.今回の測線は1983年に行われた観測の測線を西へ約10km平行移動させたものにほぼ等しいが,あいだには糸魚川-静岡構造線があって,その両側での構造の違いを明らかにすることが大きな目的である.幸い天候にも恵まれ,記録の質はどれも良好であった. 1983年の観測と比較してみると,今回の観測は6km/sのみかけ速度をもつ走時群の原点走時(インターセプトタイム)が小さく,いわゆる6km/s層が浅いものと考えられる.いくつかの後続波は地殻内部からの反射波だけではなく,この東西の構造の違いによる横方向からの屈折波である可能性がある.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"127132","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Research Group For Explosion Seismology"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032731","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":"爆破地震動研究グループ"}],"nameIdentifiers":[{"nameIdentifier":"127131","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":"ji0673002.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0673002.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32731/files/ji0673002.pdf"},"version_id":"22601155-1c96-43be-940b-930470a02944"}]},"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":"糸魚川-静岡構造線南部における爆破地震動の観測 : 早川-静岡測線","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"糸魚川-静岡構造線南部における爆破地震動の観測 : 早川-静岡測線","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4711","4712"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"32731","relation_version_is_last":true,"title":["糸魚川-静岡構造線南部における爆破地震動の観測 : 早川-静岡測線"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T05:17:21.755059+00:00"}
