Then you’ll be pleased to know that there’s no “hard science” to support A) tsunamis in the Aegean in the 2nd m BC, or B) a supereruption of Thera in 2nd m BC (or the 1st m BC for that matter).

I have been to both Santorini and Pompeii and have seen the similarity of effect of the two volcanic events. When the material immediately below the volcanic material is carbon dated to a point in time, plus or minus a reasonable measurement error, I am pretty comfortable that the dating is correct. Pompeii happened in 79 AD and Thera about 1628 BC.
