The lake origin was explained by van Bemmelen (1949) as a volcano-tectonic depression. Ninkovich (1967) explained that Lake Toba is a caldera produced by a single eruption 70,000 years BC. Geological, geo-chronology, tephra-chronology, and gravity measurements by the Japan-Indonesia surveys revealed a more complex origin, the combined effect of volcanic, tectonic and sedimentation processes starting 1.9 M years ago (Nishimura et al. 1980). Lake Toba water area is 1,129 km² excluding the 647 km² Samosir Island and several other smaller islands in the lake. The morphology formed a topographic depression surrounded by steep cliffs 400 to 1200 m above lake surface. The water is at 904.5 m above sea level, maximum depth 585 m. The joint Japan-Indonesia finding is a strong base for planning a sustainable management for local people, forestry, fisheries, agriculture benefits, industrial developments, hydropower generation, and an everlasting scenic view for tourists.", "subitem_description_type": "Abstract"}]}, "item_10_description_30": {"attribute_name": "資源タイプ（コンテンツの種類）", "attribute_value_mlt": [{"subitem_description": "Article", "subitem_description_type": "Other"}]}, "item_10_description_31": {"attribute_name": "フォーマット：mimeタイプ", "attribute_value_mlt": [{"subitem_description": "application/pdf", "subitem_description_type": "Other"}]}, "item_10_description_5": {"attribute_name": "引用", "attribute_value_mlt": [{"subitem_description": "信州大学理学部附属諏訪臨湖実験所報告 12: 3-8(2000)", "subitem_description_type": "Other"}]}, "item_10_publisher_4": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "信州大学理学部"}]}, "item_10_select_64": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_10_source_id_40": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00089817", "subitem_source_identifier_type": "NCID"}]}, "item_10_text_66": {"attribute_name": "sortkey", "attribute_value_mlt": [{"subitem_text_value": "02"}]}, "item_1627890569677": {"attribute_name": "出版タイプ", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_970fb48d4fbd8a85", "subitem_version_type": "VoR"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Hehanussa,  P.E.", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "46844", "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": "2015-09-28"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "Suwa12-02.pdf", "filesize": [{"value": "550.8 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 550800.0, "url": {"label": "Suwa12-02.pdf", "url": "https://soar-ir.repo.nii.ac.jp/record/16379/files/Suwa12-02.pdf"}, "version_id": "7bb3d5ba-06d8-4ad3-af37-25d400ac8e34"}]}, "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": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "LAKE TOBA, A MULTIPLE CALDERA DEPRESSION, NORTH SUMATERA, INDONESIA", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "LAKE TOBA, A MULTIPLE CALDERA DEPRESSION, NORTH SUMATERA, INDONESIA", "subitem_title_language": "en"}]}, "item_type_id": "10", "owner": "1", "path": ["1609"], "permalink_uri": "http://hdl.handle.net/10091/2008", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2009-02-27"}, "publish_date": "2009-02-27", "publish_status": "0", "recid": "16379", "relation": {}, "relation_version_is_last": true, "title": ["LAKE TOBA, A MULTIPLE CALDERA DEPRESSION, NORTH SUMATERA, INDONESIA"], "weko_shared_id": -1}
