Editing Mount Fuji (section)

=== Recorded eruptions ===
About 11,000 years ago, a large amount of lava began to erupt from the west side of the top of the ancient Fuji mountain. This lava formed the new Fuji, which is the main body of Mount Fuji. Since then, the tops of the ancient Fuji and the new Fuji have been side by side. About 2,500–2,800 years ago, the top part of ancient Fuji was destroyed in a large [[sector collapse]] and only the top of Shin-Fuji remained.
Ten known eruptions can be traced to reliable records.<ref>{{cite web |url=https://sakuya.vulcania.jp/koyama/public_html/Fuji/fujid/0index.html |first=Masato |last=Koyama |publisher=[[Shizuoka University]] |title=Database of eruptions and other activities of Fuji Volcano, Japan, based on historical records since AD781 |language=ja |access-date=2021-07-29 |df=dmy-all |archive-date=May 7, 2021 |archive-url=https://web.archive.org/web/20210507121143/https://sakuya.vulcania.jp/koyama/public_html/Fuji/fujid/0index.html |url-status=live }}</ref><ref>{{cite web |url=https://pandoraboss.com/2021/10/08/all-about-mount-fuji/ |title=All about Mount Fuji |language=en |access-date=October 10, 2021 |archive-date=March 5, 2023 |archive-url=https://web.archive.org/web/20230305232643/https://pandoraboss.com/2021/10/08/all-about-mount-fuji/|url-status=usurped|website=pandoraboss.com}}</ref>

| A record of this appears in the ''[[Ōdaiki]]'', a chronicle kept by the monks at [[Kubo Hachiman Shrine]] in [[Yamanashi, Yamanashi|Yamanashi City]], and it states that a flame was visible on Mount Fuji. As there is no mention of smoke, this appears to have been a [[Hawaiian eruption]] (lava only).

| The ''[[Katsuyamaki]]'' (or ''Myōhōjiki''), written by monks at Myōhō-ji in [[Fujikawaguchiko]], indicates that there was a fire on Mount Fuji at this time, but as there is no vegetation at the described location, this was almost certainly a lava flow.
