It's not entirely clear to me how it does not appear to be a precursory volcano is contradicted by The South Arch volcanic field is located upstream of the Hawaiian hotspot[10] and has been described as "precursory"[11] although it does not appear to be an early stage of a typical Hawaiian shield volcano.[3] as "precursory" is just a word while the last sentence is the actual explanation.

"before and during the last 10,000 years" does not actually define a period: every moment since the big bang falls into that period. It should be rewritten but I do not know what it should be.— SkyLined (talk)20:29, 2 July 2019 (UTC)[reply]
It was a (disarticulate) way of saying that it was active both during the last 10,000 years (in the Holocene) but also a while before. I've yanked part of the sentence as the "last 10,000 years" is the most interesting aspect. Jo-Jo Eumerus (talk, contributions) 20:53, 2 July 2019 (UTC)[reply]
