Yeah, and earthquake, even a small one, could have turned the substrate into mush. Also, it seems I may have misread this part of the article:
"This city is absolutely untouched," Goddio said. "Everything is in its original position."
I read that to mean the site was essentially buried intact, but it doesn't necessarily say that. The author probably means the site has been undisturbed since its burial at sea ;^)
Still in all, he implies(I think) the site was covered fairly quickly by sediment, which still seems odd. I mean we're talking a combination of a flood and earthquake at roughly the same time. Or at the very least a flood following on the heels of an earthquake???
I dunno. I get frustrated with this "stuff". Seems every piece I read just raises more questions than answers.
FGS
The subsequent burial under new sand probably happened because of the tides; regarding how close the nearest Nile mouth is, I dunno. Let's have a look at the archives...
