I'm not satisfied with that but it's a pretty good try.

It should be obvious that the building collapsed down hinge-fashion like I said. Follow the line, it's still attached on the right side. It may have collapsed DUE to the blast but it is in no way indicative of any blast PATTERN. That would now be UNDER the still-attached-on-one-side roof section, so there's no conceivable way you can determine the original shape of the hole immediately after the pl--I mean, explosion.
