The Tianwenfeng eruption was the formation of a widespread thick layer of grey, yellow pumice preceding the Millennium eruption.<ref name=":2" /><ref name=":3" /><ref name=":4" /><ref name=":5">{{Cite journal |last1=Sun |first1=Chunqing |last2=Liu |first2=Jiaqi |last3=You |first3=Haitao |last4=Nemeth |first4=Karoly |year=2017 |title=Tephrostratigraphy of Changbaishan volcano, northeast China, since the mid-Holocene |url=https://linkinghub.elsevier.com/retrieve/pii/S0277379117305115 |journal=Quaternary Science Reviews |language=en |volume=177 |pages=104–119 |doi=10.1016/j.quascirev.2017.10.021 |bibcode=2017QSRv..177..104S}}</ref><ref>{{Cite journal |last1=Chen |first1=Xuan-Yu |last2=Blockley |first2=Simon P.
