Focal mechanism solutions are determined from the S-wave polarization angles. Fault planes, which are distinguished from the auxiliary planes by means of the hypocenter distribution of aftershocks, are slightly dipping toward the island arc. A linear correlation is found between the dip angle of fault plane and the distance of epicenter from the trench axis; the dip angle increases with increasing distance. The motion directions of the foot wall blocks relative to the hanging wall sides are in the range from N58°W to N72°W and are consistent with the expectation from the plate tectonics theory, the motion direction of the Pacific plate relative to the Eurasia plate. The focal depths re-determined by the use of depth phases such as pP and sP reveal that the hypocenters of the six earthquakes lie almost on a plane slightly dipping toward the island arc. The spectral analysis of P-waves is made to elucidate the dynamic source process. To do this, the effects of multiple reflection in the crust near the source region as well as beneath the station are taken into account. A unilateral bidirectional model of faulting appropriate to each event is determined by comparing the trough frequencies in the observed P-wave spectra with those expected theoretically. The fracture is found to have propagated in the motion direction of the foot wall block with a velocity between 2.0 and 3.1km/sec.", "subitem_description_type": "Abstract"}]}, "item_6_description_30": {"attribute_name": "資源タイプ（コンテンツの種類）", "attribute_value_mlt": [{"subitem_description": "Article", "subitem_description_type": "Other"}]}, "item_6_description_5": {"attribute_name": "引用", "attribute_value_mlt": [{"subitem_description": "Journal of Physics of the Earth. 26(3):275-297 (1978)", "subitem_description_type": "Other"}]}, "item_6_link_3": {"attribute_name": "信州大学研究者総覧へのリンク", "attribute_value_mlt": [{"subitem_link_text": "IZUTANI, Yasuo", "subitem_link_url": "http://soar-rd.shinshu-u.ac.jp/profile/ja.HFSpZVkh.html"}]}, "item_6_publisher_4": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "CENTER ACADEMIC PUBL JAPAN"}]}, "item_6_relation_48": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_name": [{"subitem_relation_name_text": "10.4294/jpe1952.26.275"}], "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.4294/jpe1952.26.275", "subitem_relation_type_select": "DOI"}}]}, "item_6_rights_62": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "Copyright© 1978 The Seismological Society of Japan; The Geodetic Society of Japan; The Volcanological Society of Japan"}]}, "item_6_select_64": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_6_source_id_35": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0022-3743", "subitem_source_identifier_type": "ISSN"}]}, "item_6_source_id_39": {"attribute_name": "NII ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0022-3743", "subitem_source_identifier_type": "ISSN"}]}, "item_6_source_id_40": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA00704960", "subitem_source_identifier_type": "NCID"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "IZUTANI,  Yasuo"}], "nameIdentifiers": [{"nameIdentifier": "37896", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "HIRASAWA,  Tomowo"}], "nameIdentifiers": [{"nameIdentifier": "37897", "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": "2015-09-28"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "1978_Izutani_Hirasawa_JPE.pdf", "filesize": [{"value": "1.9 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 1900000.0, "url": {"label": "1978_Izutani_Hirasawa_JPE.pdf", "url": "https://soar-ir.repo.nii.ac.jp/record/12441/files/1978_Izutani_Hirasawa_JPE.pdf"}, "version_id": "8e4d589d-3b12-4136-9138-a0eb99ab254a"}]}, "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": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "SOURCE CHARACTERISTICS OF SHALLOW EARTHQUAKES IN THE NORTHERN PART OF SANRIKU-OKI REGION, JAPAN", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "SOURCE CHARACTERISTICS OF SHALLOW EARTHQUAKES IN THE NORTHERN PART OF SANRIKU-OKI REGION, JAPAN", "subitem_title_language": "en"}]}, "item_type_id": "6", "owner": "1", "path": ["1222"], "permalink_uri": "http://hdl.handle.net/10091/14204", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2012-03-13"}, "publish_date": "2012-03-13", "publish_status": "0", "recid": "12441", "relation": {}, "relation_version_is_last": true, "title": ["SOURCE CHARACTERISTICS OF SHALLOW EARTHQUAKES IN THE NORTHERN PART OF SANRIKU-OKI REGION, JAPAN"], "weko_shared_id": -1}
