The observational results in the periods from October 31 to December 18, 1965, from February 20 to June 20, 1966 and from June 21 to September 20, 1966 have been reported in the previous papers. Following from these papers, the present paper will report the results obtained at Hoshina in the period from the latter part of September to November, 1966. In addition the observational result obtained at the Sanada station, which was newly established in September 1966, will be reported together with a description of the observational and analytical method adopted there. At the present time, the Matsushiro earthquakes are observed by the temporary seismographic network with the acceleration seismographs and the HES electromagnetic seismographs set up at Hoshina, Akashiba, Zozan, Mori, Sakaki, etc. Besides this ordinary method of observation, the high sensitivity tripartite observation is carried out in and near the area of Matsushiro Earthquakes, i.e., at Hoshina (36\u00b035\u0027N, 138\u00b016\u0027E), Sanada (36\u00b026\u0027N, 138\u00b018\u0027E) , Kamimuroga (36\u00b024\u0027N, 138\u00b09\u0027E) and Asakawa (36\u00b041\u0027N, 138\u00b011\u0027E). Analysing the observational data from these seismographic stations, we found that the hypocenters could not be determined consistently with all observational data if we assume a uniform underground structure. However, we found it difficult, at the same time, to determine or assume any complicated structure immediately. Therefore we adopted as before the assumption of the uniform structure as a first approximation when determining the hypocenters. The hypocenters of the Matsushiro earthquakes should be determined more exactly on the basis of the most suitable underground structure, so our intention is to make further study on this problem using all data obtained at various stations in the area of Matsushiro. The results of this study will be reported at the next opportunity.", "subitem_description_type": "Abstract"}, {"subitem_description": "\u677e\u4ee3\u5730\u9707\u5730\u57df\u306b\u304a\u3051\u308b\u5fae\u5c0f\u53ca\u3073\u6975\u5fae\u5c0f\u5730\u9707\u306e\u6d3b\u52d5\u3092\u8abf\u3079\u308b\u76ee\u7684\u3067,\u9ad8\u611f\u5ea63\u70b9\u65b9\u5f0f\u306b\u3088\u308b\u5730\u9707\u89b3\u6e2c\u304c,\u82e5\u7a42\u753a\u4fdd\u79d1\u306b\u304a\u3044\u3066, 1965\u5e7411\u6708\u304b\u3089\u884c\u306a\u308f\u308c\u3066\u3044\u308b.\u305d\u306e\u7d50\u679c\u306f\u3059\u3067\u306b\u7b2c1\u5831\uff5e\u7b2c3\u5831\u3067\u5831\u544a\u3057\u3066\u3042\u308b.\u4eca\u56de\u306f\u305d\u306e\u7d9a\u304d\u3068\u3057\u3066, 1966\u5e749\u6708\u4e0b\u65ec\uff5e11\u6708\u4e0b\u65ec\u306e\u671f\u9593\u306e\u82e5\u7a42\u753a\u4fdd\u79d1\u3067\u306e\u89b3\u6e2c\u7d50\u679c\u3068\u540c\u5e749\u6708\u306b\u65b0\u8a2d\u3055\u308c\u305f\u771f\u7530\u753a\u30fb\u9577\u3067\u306e\u89b3\u6e2c\u7d50\u679c\u306e\u5831\u544a\u3067\u3042\u308b.\u82e5\u7a42\u753a\u4fdd\u79d1\u3067\u306e\u89b3\u6e2c\u53ca\u3073\u89e3\u6790\u306e\u65b9\u6cd5\u306f\u4ee5\u524d\u3068\u91cd\u5fa9\u3059\u308b\u306e\u3067\u3053\u3053\u3067\u306f\u7701\u304d,\u3053\u3053\u3067\u306f\u65b0\u3057\u304f\u59cb\u3081\u3089\u308c\u305f\u771f\u7530\u753a\u30fb\u9577\u3067\u306e\u89b3\u6e2c\u53ca\u3073\u89e3\u6790\u306e\u65b9\u6cd5\u306b\u3064\u3044\u3066\u306e\u307f\u89b3\u6e2c\u7d50\u679c\u3068\u5171\u306b\u5831\u544a\u3059\u308b.", "subitem_description_type": "Abstract"}]}, "item_4_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "130921", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "\u6d5c\u7530, \u548c\u90ce"}]}, {"nameIdentifiers": [{"nameIdentifier": "130922", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "\u8429\u539f, \u5c0a\u793c"}]}]}, "item_4_identifier_registration": {"attribute_name": "ID\u767b\u9332", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.15083/0000033519", "subitem_identifier_reg_type": "JaLC"}]}, "item_4_publisher_20": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u6771\u4eac\u5927\u5b66\u5730\u9707\u7814\u7a76\u6240"}]}, "item_4_source_id_10": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "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": "\u65e5\u672c\u5341\u9032\u5206\u985e\u6cd5", "attribute_value_mlt": [{"subitem_subject": "453", "subitem_subject_scheme": "NDC"}]}, "item_4_text_21": {"attribute_name": "\u51fa\u7248\u8005\u5225\u540d", "attribute_value_mlt": [{"subitem_text_value": "Earthquake Research Institute, University of Tokyo"}]}, "item_4_text_34": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"subitem_text_value": "Departmental Bulletin Paper"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Hamada, Kazuo"}], "nameIdentifiers": [{"nameIdentifier": "130919", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Hagiwara, Takahiro"}], "nameIdentifiers": [{"nameIdentifier": "130920", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2017-06-26"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "ji0451010.pdf", "filesize": [{"value": "2.0 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 2000000.0, "url": {"label": "ji0451010.pdf", "url": "https://repository.dl.itc.u-tokyo.ac.jp/record/33519/files/ji0451010.pdf"}, "version_id": "5514a7c1-4af8-42d6-a75b-efac701fbb60"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "High Sensitivity Tripartite Observation of Matsushiro Earthquakes.
