I think that idea (widespread, simultaneous large earthquakes shaking down city walls and whatnot, ending the so-called Bronze Age) has been around a good long time. Blegen claimed that the layer of Troy just before the Trojan War (IOW, Troy VI, which was most extensively excavated and mapped by Dorpfeld) was destroyed or at least dismantled by a quake, and that Troy VIIa was the already-wrecked city of the Iliad. Dorpfeld said it was VI, and I agree with that. :’)
Well, I went to save that one, and found I had it on the drive already. :’D He’s also a peak oil guy (Nur, I mean), and attributes the 9/11 terrorist attacks to oil (IOW, I think he needs to shuddup about stuff not related to earthquakes etc).
