In the interval of one year following the main shock, the active area clearly expanded outward in most cases. The pattern of the expansion, however, is different for different areas, as are the size and the shape of the aftershock area. A sharp contrast in these features of aftershock sequences between Japan and Aleutian-Alaska suggests a difference of the mechanism of aftershock occurrence in both areas. Moreover, a rapid systematic propagation of the aftershock activity during several hours following the main shock was found for the Aleutian Earthquake of 1957 and the Alaska Earthquake of 1964. From the standpoint of the fracture theory of earthquakes, these features in the development of the aftershock region are attributed to the nature of brittle fracture.|\u5927\u5730\u9707\u306e\u767a\u751f\u6a5f\u69cb\u3092\u7814\u7a76\u3059\u308b\u4e00\u3064\u306e\u65b9\u6cd5\u3068\u3057\u3066,\u305d\u306e\u4f59\u9707\u306e\u767a\u751f\u7279\u6027\u3092\u7814\u7a76\u3059\u308b\u3053\u3068\u304c\u8003\u3048\u3089\u308c\u308b.\u500b\u3005\u306e\u5927\u5730\u9707\u306b\u3064\u3044\u3066\u306f,\u304b\u306a\u308a\u8a73\u3057\u3044\u7814\u7a76\u304c\u884c\u306a\u308f\u308c\u3066\u304e\u305f\u306e\u306b\u5bfe\u3057\u3066,\u3053\u308c\u3089\u306e\u5927\u5730\u9707\u306b\u5171\u901a\u306a\u7279\u6027\u306e\u7cfb\u7d71\u7684\u306a\u7814\u7a76\u306f\u5fc5\u305a\u3057\u3082\u5341\u5206\u3067\u306f\u306a\u3044.\u672c\u8ad6\u6587\u3067\u306f,\u6d45\u767a\u6ce8\u306e\u5927\u5730\u9707\u306e\u4f59\u9707\u6d3b\u52d5\u306e\u7a7a\u9593\u7684\u306a\u5206\u5e03,\u3068\u304f\u306b\u305d\u306e\u6642\u9593\u7684\u306a\u5909\u5316\u3092\u51fa\u6765\u308b\u3060\u3051\u591a\u304f\u306e\u4f8b\u306b\u3064\u3044\u3066\u3057\u3089\u3079,\u5927\u5730\u9707\u306e\u4f59\u9707\u306e\u8d77\u3053\u308a\u65b9\u3092\u660e\u3089\u304b\u306b\u3059\u308b\u3053\u3068\u3092\u8a66\u307f\u305f.\u6b21\u306b\u305d\u306e\u7d50\u679c\u3092\u8981\u7d04\u3059\u308b.", "subitem_description_type": "Abstract"}]}, "item_4_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "130652", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "\u8302\u6728, \u6e05\u592b"}]}]}, "item_4_identifier_registration": {"attribute_name": "ID\u767b\u9332", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.15083/0000033448", "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_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": "Mogi, Kiyoo"}], "nameIdentifiers": [{"nameIdentifier": "130651", "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": "ji0462001.pdf", "filesize": [{"value": "1.6 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1600000.0, "url": {"label": "ji0462001.pdf", "url": "https://repository.dl.itc.u-tokyo.ac.jp/record/33448/files/ji0462001.pdf"}, "version_id": "2dffb0ff-be4e-4c61-95c2-6107ab3cb2bf"}]}, "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": "10.
