Description: From Waythomas and others (1999): "The second of the two fine-grained ash layers found on the Kenai Peninsula is geochemically similar to the proximal lapilli tephra and dates to about 7,000 yr B.P. This ash bed is evidence for an older plinian(?) eruption of Iliamna Volcano but so far no associated volcanic deposits have been identified on the proximal flanks of the volcano."

The Global database on large magnitude explosive volcanic eruptions (LaMEVE; 2017) reports a magnitude of 4.000, bulk eruptive volume of 0.100 cubic km and a dense rock equivalent eruptive volume of 0.040 cubic km for the eruption.
