How much is enough to level a city block?

[Tisthammerw]

Take this scene from Blade II

Nyssa: They tell bedtime stories about you. Blade the big, bad boogie-man. Frankly, I'm disappointed.

(Blade raises an eyebrow)

Nyssa: That you were willing to come along so easily, I mean. Without any assurances.

Blade smiles and opens his coat, revealing a good amount of plastic explosives attached to him.

Blade: Semtex explosive. Enough to level a city block. How's that for assurance?

I suspect most of us have heard the phrase (or something like it) "enough to level a city block," but how much is that? Is Blade’s remark realistic? (Semtex is a real explosive by the way.) How much Semtex or TNT would it take to do the job?

I imagine it would vary for the circumstances, e.g. one big bomb or standard demolition methods. In that case, how much for each?

I'm closing this until Russ or Enigma has a chance to take a look. I don't think this is an appropriate discussion.

It would literally take a truckload (a small truckload, but a truckload, nonetheless). And yeah, I'm ok with keeping this closed...
