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_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_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_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":[{}]}]},"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","filename":"Suwa12-02.pdf","filesize":[{"value":"550.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","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"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-02-27"},"publish_date":"2009-02-27","publish_status":"0","recid":"16379","relation_version_is_last":true,"title":["LAKE TOBA, A MULTIPLE CALDERA DEPRESSION, NORTH SUMATERA, INDONESIA"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-09T02:03:57.220745+00:00"}
