Augustine reported activity





Event Name : Augustine Tephra H

Start: 1450 (± 50 Years) Years BP C-14 (raw)

Tephrafall: BibCard BibCard BibCard BibCard BibCard BibCard
Eruption Type:Explosive

Description: From Waitt and Beget (2009): "The lowest five coarse-pumice beds at the coast-tephras G, I, H, C, and O-drifted east and southeast. Tephra G and ambiguous tephra O are known only from a few sites each on the east and southeast, neither with enough data points to warrant a map. Drawn from data at many stratigraphic exposures, isopach maps clearly show tephras I, H, and C drifted east-southeast and southeast."

"Several decimeters of thin beds of fine sand to silt (ash) separate tephra layers I and H (fig. 6 [in original text])."

From Tappen and others (2009): "...tephra H is a 8- to 9-cm thick layer of fine-grained gray silty ash with pumiceous lapilli."
