Great Sitkin 7600 yBP
Start: 7600 yBP [1]
Stop: 7300 yBP [1]
Event Type: Explosive
- Tephrafall [1]
Description: From Waythomas and others (2003): "Pumice and lithic lapilli tephra deposit (Main ash?)."
Note that Waythomas and others (2001) suggest that Moffett is the source of the Main ash. Unclear whether this ash is indeed the Main ash (i.e. erupted by Moffett and deposited on Great Sitkin), or an ash erupted by Great Sitkin and incorrectly thought to be the Main ash.
