Aniakchak reported activity




Event Name : Aniakchak New Cone Tephra

Start: 400 (± 30 Years) Years BP C-14 (raw)

Tephrafall: BibCard BibCard
Eruption Type:Explosive

Description: From Bacon and others (2014): "On the east-southeast flank of Vent Mountain, New Cone was the source of lava that preceded much of that from Vent Mountain itself. Three radiocarbon dates on material associated with tephra thought to have a New Cone source (table 2 [in original text]) have a weighted mean age of 400+/-30 yr B.P. (table 1 [in original text]), though only the 390+/-60 yr B.P. date is from within the caldera. Tephra considered to predate New Cone is as young as Half Cone upper light pumice."
