LOL, no, I don’t think it has anything to do with you being stupid or your lack of coffee!
I may have misread the Wikipedia entry which spoke of the Minoan segment living on Crete, which was over 100km from the eruption and didn’t get much.
From what I can tell, the Minoans on Crete were like an outpost or Minoan colony, where the ones that got entombed on Santorini were the main body?
My knowledge of history during those times is spotty at best...I defer to you on this!
Looks like some others weighed in and explained that Crete was the “big island” and Thera was probably the hub. I am working on a novel set on Thera a few generations before the explosion and have about every book published in English I can find, so I had to jump in there! ;)
