re: #67 Charles Johnson

Have to disagree here - definitely not big enough to be a nuke. We’re talking several orders of magnitude. A nuke would have completely leveled a large area (depending on how many megatons it was) and there would have been many more people dead.

I linked to a BBC report downstairs that the seismic guys said the second blast was 21 tons—that’s 1/1000 of the Nagasaki bomb’s yield.
