ERI conducted questionnaire surveys for significant earthquakes from 1943 to 1988. In these surveys, the 12-class seismic intensity scale (Ik), which is similar to the Modified Mercalli intensity scale (MMI-scale), was used. Survey results for earthquakes after 1950 were investigated and published, but the survey results for earthquakes in the 1940s have not been published and the original sheets of the surveys were considered to be missing. In addition to 199 original questionnaires and summary sheets discovered in recent years, we discovered an additional 91 original sheets. In this study, we examine the 289 original questionnaire sheets, excluding one without location information. Because multiple intensity values are obtained for various kinds of damage and detailed human behaviors at each survey point, representative values of seismic intensities at a point are necessary to make a seismic intensity distribution map. In previous studies, the mean value of seismic intensities was used as a representative value, but the mean value saturates at Ik 8-9 (corresponding to V on old JMA\u0027s intensity scale) because of a larger reported number of lower intensities. The mean of the top five seismic intensity reports hardly saturates and its distribution is similar to that reported by the Central Meteorological Observatory (CMO), as well as the distribution of slight house damage. While the number of newly estimated seismic intensities is less than 60% of the CMO\u0027s seismic intensities, the new seismic intensity distribution map clarifies some characteristics of 1944 seismic ground motions. (1) High intensities (Ik 6-9) are estimated not only in the northeastern region of Biwa Lake in Shiga Prefecture, but also in the entire prefecture around the lake. (2) High intensities (Ik 6-7) are estimated in the Ina Valley in Nagano Prefecture where two previous Tokai earthquakes also caused damage. (3) Seismic ground motions are strongly amplified (Ik 7-8) in the Fukui Plain, which is more than 200km from the 1944 source. (4) Seismic intensities along the Pacific coast of Tokushima Prefecture are high (Ik 6-7). (5) Significantly higher seismic intensities (Ik 8) are estimated in the eastern part of Saitama Prefecture than those in the surrounding region. In this region, other earthquakes such as the 1854 Ansei Tokai earthquake (M8.4) and the 1923 Kanto earthquakes (M7.9) also caused abnormally high seismic intensities, while the cause of such high intensities has not been clarified yet.", "subitem_description_type": "Abstract"}]}, "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_select_14": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "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_text_21": {"attribute_name": "\u51fa\u7248\u8005\u5225\u540d", "attribute_value_mlt": [{"subitem_text_value": "Earthquake Research Institute, University of Tokyo"}]}, "item_4_text_4": {"attribute_name": "\u8457\u8005\u6240\u5c5e", "attribute_value_mlt": [{"subitem_text_value": "\u6771\u4eac\u5927\u5b66\u5730\u9707\u7814\u7a76\u6240"}, {"subitem_text_value": "\u56fd\u7acb\u79d1\u5b66\u535a\u7269\u9928"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "\u539f\u7530, \u667a\u4e5f"}], "nameIdentifiers": [{"nameIdentifier": "145405", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u4f50\u7af9, \u5065\u6cbb"}], "nameIdentifiers": [{"nameIdentifier": "145406", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u53e4\u6751, \u5b5d\u5fd7"}], "nameIdentifiers": [{"nameIdentifier": "145407", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u5ba4\u8c37, \u667a\u5b50"}], "nameIdentifiers": [{"nameIdentifier": "145408", "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": "2017-12-05"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "IHO92101.pdf", "filesize": [{"value": "17.4 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 17400000.0, "url": {"label": "IHO92101.pdf", "url": "https://repository.dl.itc.u-tokyo.ac.jp/record/48915/files/IHO92101.pdf"}, "version_id": "b3070245-2f1c-4afa-b018-fee143ce67e0"}]}, "item_keyword": {"attribute_name": "\u30ad\u30fc\u30ef\u30fc\u30c9", "attribute_value_mlt": [{"subitem_subject": "1944 Tonankai earthquake", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Seismic intensity", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Questionnaire survey", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Kawasumi\u0027s intensity scale", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Old and new JMA\u0027s intensity scales", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "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": "1944\u5e74\u6771\u5357\u6d77\u5730\u9707\uff08M7.9\uff09\u306e\u9707\u5ea6\u5206\u5e03 : \u767a\u751f\u76f4\u5f8c\u306b\u884c\u308f\u308c\u305f\u30a2\u30f3\u30b1\u30fc\u30c8\u8abf\u67fb\u8cc7\u6599\u306e\u518d\u691c\u8a0e", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "1944\u5e74\u6771\u5357\u6d77\u5730\u9707\uff08M7.9\uff09\u306e\u9707\u5ea6\u5206\u5e03 : \u767a\u751f\u76f4\u5f8c\u306b\u884c\u308f\u308c\u305f\u30a2\u30f3\u30b1\u30fc\u30c8\u8abf\u67fb\u8cc7\u6599\u306e\u518d\u691c\u8a0e", "subitem_title_language": "ja"}]}, "item_type_id": "4", "owner": "1", "path": ["80/4535/7677/7678", "9/504/4538/7675/7676"], "permalink_uri": "http://hdl.handle.net/2261/00074040", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2017-12-05"}, "publish_date": "2017-12-05", "publish_status": "0", "recid": "48915", "relation": {}, "relation_version_is_last": true, "title": ["1944\u5e74\u6771\u5357\u6d77\u5730\u9707\uff08M7.9\uff09\u306e\u9707\u5ea6\u5206\u5e03 : \u767a\u751f\u76f4\u5f8c\u306b\u884c\u308f\u308c\u305f\u30a2\u30f3\u30b1\u30fc\u30c8\u8abf\u67fb\u8cc7\u6599\u306e\u518d\u691c\u8a0e"], "weko_shared_id": -1}
