All the parameters are estimated using maximum likelihood methods with their error assessments except the fractal dimension of hypocenter distributions are estimated by both the least squares and maximum likelihood methods. \u003cbr /\u003e　　For the majority of the aftershock sequenceds, the ETAS model has a smaller AIC value than the nonstationary Poisson mdels with the modified Omori intensity function, which suggests existence of clusters within the aftershock sequence. Most of the scatterplots between the maximum likelihood estimates of the characteristic parameters are seen to be either positively or negatively correlated. Clear positive correlations between the parameters of b, p of the least square method, are seen for the intraplate earthquakes, but that was not clear for interplate events except(b, D)\u003cbr /\u003e　　On the other hand, we estimated the P values using the ETAS model, and the fractal dimension D by the maximum likelihood. Thus, we investigated correlations between P and αvalue of the ETAS model, b, and the fractal dimension D. The contrasting correlation patterns are revealed between the estimated parameters for the intraplate and interplate earthquakes, except for the two pairs (b, D) and (α, p) in which similar correlation patterns are found.\u003cbr /\u003e　　We then focus our attention on these patterns as a source of interesting contrasts between the two earthquake groups, i.e. the intraplate and interplate events. In particular, the significant dependence of these parameters on the depth appears a key to understand the correlation pattern for interplate aftershocks, while a different interpretation is made for intraplate aftershocks because no dependence on depth is observed.", "subitem_description_type": "Other"}]}, "item_1_description_7": {"attribute_name": "学位記番号", "attribute_value_mlt": [{"subitem_description": "総研大甲第241号", "subitem_description_type": "Other"}]}, "item_1_select_14": {"attribute_name": "所蔵", "attribute_value_mlt": [{"subitem_select_item": "有"}]}, "item_1_select_8": {"attribute_name": "研究科", "attribute_value_mlt": [{"subitem_select_item": "数物科学研究科"}]}, "item_1_select_9": {"attribute_name": "専攻", "attribute_value_mlt": [{"subitem_select_item": "15 統計科学専攻"}]}, "item_1_text_10": {"attribute_name": "学位授与年度", "attribute_value_mlt": [{"subitem_text_value": "1996"}]}, "item_1_text_20": {"attribute_name": "業務メモ", "attribute_value_mlt": [{"subitem_text_value": "（2018年2月13日）本籍など個人情報の記載がある旧要旨・審査要旨を個人情報のない新しいものに差し替えた。承諾書等未確認。要確認該当項目修正のこと。"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "GUO, Zhen Qi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "9022", "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": "2016-02-17"}], "displaytype": "simple", "download_preview_message": "", "file_order": 0, "filename": "甲241_要旨.pdf", "filesize": [{"value": "352.3 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_11", "mimetype": "application/pdf", "size": 352300.0, "url": {"label": "要旨・審査要旨 / Abstract, Screening Result", "url": "https://ir.soken.ac.jp/record/731/files/甲241_要旨.pdf"}, "version_id": "10990195-09cd-4f71-8953-88d3f7818b78"}]}, "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": "thesis", "resourceuri": "http://purl.org/coar/resource_type/c_46ec"}]}, "item_title": "Statistical Analyses of Aftershocks for the Relations Between Their Models in Time, Space, and Magnitude", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Statistical Analyses of Aftershocks for the Relations Between Their Models in Time, Space, and Magnitude"}, {"subitem_title": "Statistical Analyses of Aftershocks for the Relations Between Their Models in Time, Space, and Magnitude", "subitem_title_language": "en"}]}, "item_type_id": "1", "owner": "1", "path": ["17"], "permalink_uri": "https://ir.soken.ac.jp/records/731", "pubdate": {"attribute_name": "公開日", "attribute_value": "2010-02-22"}, "publish_date": "2010-02-22", "publish_status": "0", "recid": "731", "relation": {}, "relation_version_is_last": true, "title": ["Statistical Analyses of Aftershocks for the Relations Between Their Models in Time, Space, and Magnitude"], "weko_shared_id": 1}
