Besides these, 12 sea measurements have been made in the sea around Japan as a joint program of the University of Tokyo and the Japan Meteorological Agency.Of the total of 39 land stations, 26 are metal mines, 4 coal mines, 2 oil fields, 3 natural gas fields, 1 railway tunnel and 3 sites of other types. In each of these stations heat flux was estimated from the geothermal gradient combined with the thermal conductivity of rocks in which the thermal gradient was measured. An outline of the method used to measure thermal gradients and thermal conductivity is described. Temperatures were measured in deep or in short bore holes for geothermal gradient assessment. The maximum depth of temperature measurement exceeded several hundred meters at most of the land stations. In the course of the temperature measurement, two types of underground isothermal surfaces were discerned and their origin investigated. Values of the thermal gradient on land varied from 0.5\u00b0 to 5.0\u2103/100m; except those areas which are considered to be geothermally anomalous. Thermal conductivity was determined by the divided-bar method. The apparatus was calibrated with standard substances of knownconductivity. In the course of this study, measurements were made on over 240 sets of rock samples covering 36 rock types. In this paper, the results are presented in a diagram according to theirrock types. These values range from 2\u00d710-3 to 15\u00d710-3 cal/cm sec \u2103. Errors accompanying the calculation of heat flow values wereestimated from the probable variation in the thermal gradient andthe degree of ambiguity in assessing the in situ thermal conductivity of the strata as based on the thermal conductivities ofindividual samples. In most cases, the error amounts to a fewtenths of 1 \u03bccal/cm2 sec or 20 to 30 per centum of the observedheat flow value. From the 39 land and 12 sea measurements, general tendencyof terrestrial heat flow distribution in and around Japan can bevisualized. Characteristic features of the distribution are as follows: i) A region of high heat flow exists on the inner side of the Japanese arc, where the heat flow value exceeds 2 \u03bccal/cm2 sec. ii) A region of low heat flow (less than 1 \u03bccal/cm2 sec) exists on the Pacific Ocean side of north-eastern Honshu, iii) There may be a high heat flow region in the Pacific far off the coast of north eastern Honshu, iv) In regions other than the above, almost all the heat flow values on land are between 1 and 2 \u03bccal/cm2 sec.", "subitem_description_type": "Abstract"}, {"subitem_description": "\u6771\u4eac\u5927\u5b66\u5730\u9707\u7814\u7a76\u6240\u306b\u3088\u3064\u30661957\u5e74\u4ee5\u6765\u884c\u306a\u308f\u308c\u3066\u304d\u305f\u5730\u6bbc\u71b1\u6d41\u91cf\u306e\u6e2c\u5b9a\u306f1962\u5e7412\u6708\u307e\u3067\u306b,\u65e5\u672c\u5404\u5730\u306e39\u5730\u70b9\u3067\u884c\u306a\u308f\u308c\u305f.\u4ed6\u306b\u6c17\u8c61\u5e81\u3068\u5354\u540c\u3057\u3066\u884c\u306a\u3064\u305f\u6d77\u6d0b\u89b3\u6e2c\u306b\u3088\u3064\u3066,\u6d77\u57df\u306b\u308212\u5730\u70b9\u3067\u306e\u6e2c\u5b9a\u7d50\u679c\u304c\u3042\u308b.\u9678\u4e0a\u3067\u884c\u306a\u3063\u305f39\u306e\u6e2c\u5b9a\u306e\u3046\u3061,26\u306f\u91d1\u5c5e\u9271\u5c71,4\u306f\u70ad\u783f,2\u306f\u6cb9\u4e95,3\u306f\u5929\u7136\u30ac\u30b9\u4e95,1\u306f\u9244\u9053\u9042\u9053,\u4ed6\u306e3\u306f\u305d\u306e\u4ed6\u306e\u76ee\u7684\u306e\u305f\u3081\u306b\u6398\u5879\u3055\u308c\u305f\u8a66\u9310\u5b54\u3092\u5229\u7528\u3057\u305f\u3082\u306e\u3067\u3042\u308b\uff0e\u5730\u6bbc\u71b1\u6d41\u91cf\u306f\u5730\u4e0b\u6e29\u5ea6\u5897\u52a0\u7387\u3068\u5730\u5c64\u306e\u71b1\u4f1d\u9ad8\u7387\u306e\u7a4d\u3068\u3057\u3066\u6c42\u3081\u305f.", "subitem_description_type": "Abstract"}]}, "item_4_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "131594", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "\u5b9d\u6765, \u5e30\u4e00"}]}]}, "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_4_text_4": {"attribute_name": "\u8457\u8005\u6240\u5c5e", "attribute_value_mlt": [{"subitem_text_value": "Earthquake Research Institute"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "HORAI, Ki-iti"}], "nameIdentifiers": [{"nameIdentifier": "131593", "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": "", "filename": "ji0421005.pdf", "filesize": [{"value": "2.3 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 23000000, "url": {"label": "ji0421005.pdf", "url": "https://repository.dl.itc.u-tokyo.ac.jp/record/33688/files/ji0421005.pdf"}, "version_id": "6558d4ed-44b9-49a0-babb-0b928dff68ab"}]}, "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": "5.
