Wiped Out By A "Heat Event"

Come back, it's not about global warming! Archaeologists are excavating sites believed to be Sodom & Gomorrah.
The cities at the site were suddenly and completely wiped out in the Late Bronze Age, which makes a reasonably good fit with the biblical accounts of Abraham and Lot.  The entire presentation was very convincing, but never once did they deal with the "elephant in the room": what caused the sites to be suddenly abandoned?  As soon as the session was over, I was the first to raise my hand.  "Did you find any arrow heads?  Signs of invasion?  What happened to them?"  The lead archeologist paused for a moment.  "I didn't want to go there," he said.  Another pause. "I'm preparing material for publication."  Pause.  "All I want to say 'on camera' is, they appear to have been wiped out in a 'heat event'."
The expert wasn't willing to speak of his findings on the record. 
I wish I could divulge what he said to a small group of us clustered around the podium after the session was over, but it would break confidence.  We'll have to wait for the official peer-reviewed publications.
Boy howdy, don't bet against the Bible. Isn't that cool?
