Three eruptive stages are recognized. During early or middle Pleistocene the Matsuozawa volcano was formed; this is the first stage. The second stage was initiated by effusion of the Horaguchi lava, which was followed by eruptions of the Oshi pyroclastic flow, older lava flows, 3P pumice fall, and Yazawahara pyroclastic flow. Brown loess soil about 10m thick covering these deposits indicates that a dormant period of more than 100, 000 years followed this stage. The summit area upheaved about 400m or more against the foot of the volcano during this period, as is suggested by the extraordinarily steep (6.1°-3.0°) surface of the Oshi ignimbrite plateau. The third stage, which started about 14, 000 years ago, is the formation of three pyroclastic cones on the summit and contemporaneous effusion of the younger lava flows, <i>e. g.</i> the Kagusa lava of 7, 000 years ago and the Sessyo lava of 3, 000 years ago. In historic times, phreatic explosions have frequently occurred on the summit crater, Yugama. This means that the present belongs to the third stage. It is unlikely that eruptions of the third stage are caused by cooling of the magma chamber which was active in the second stage. The activity of the third stage seems to denote arrival of a new magma chamber at shallow depth."}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1030003658319722881","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"40198825"},{"@type":"NRID","@value":"1000040198825"},{"@type":"NRID","@value":"9000380476592"},{"@type":"NRID","@value":"9000002496517"},{"@type":"NRID","@value":"9000024610201"},{"@type":"NRID","@value":"9000243845298"},{"@type":"NRID","@value":"9000243845297"},{"@type":"NRID","@value":"9000004598017"},{"@type":"NRID","@value":"9000405645533"},{"@type":"NRID","@value":"9000237820726"},{"@type":"NRID","@value":"9000323843866"},{"@type":"NRID","@value":"9000254084538"},{"@type":"NRID","@value":"9000003384384"},{"@type":"NRID","@value":"9000364800670"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/read0099477"}],"foaf:name":[{"@language":"en","@value":"HAYAKAWA Yukio"},{"@language":"ja","@value":"早川 由紀夫"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Department of Geography, Faculty of Science, Tokyo Metropolitan University"},{"@language":"ja","@value":"東京都立大学理学部地理学教室"}]},{"@id":"https://cir.nii.ac.jp/crid/1410572172310791040","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000021575305"}],"foaf:name":[{"@language":"en","@value":"YUI Masao"},{"@language":"ja","@value":"由井 将雄"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Earthquake Research Institute, University of Tokyo"},{"@language":"ja","@value":"東京大学地震研究所"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"04182642"},{"@type":"LISSN","@value":"04182642"},{"@type":"EISSN","@value":"18818129"},{"@type":"NDL_BIB_ID","@value":"000000014125"},{"@type":"ISSN","@value":"04182642"},{"@type":"PISSN","@value":"http://id.crossref.org/issn/04182642"},{"@type":"NCID","@value":"AN0034136X"}],"prism:publicationName":[{"@language":"en","@value":"The Quaternary Research (Daiyonki-Kenkyu)"},{"@language":"ja","@value":"第四紀研究"},{"@language":"en","@value":"The Quaternary Res."},{"@language":"en","@value":"The Quat.
