You should be very cautious with the info provided in the two linked sites. I noticed several "iffy" things such as, for example, the mention of two volcanic eruptions during antiquity, bla, bla. Well, yes, there are writings of ancient Greeks that say that "in ancient" years there were volcanic eruptions but hat brings us way beyond what we understand to day by "antiquity"; any volcano on the island is not only dormant but completely "off"!
