What advantage do they gain by making the claim without being able to actually do it?

We'll give them stuff to bribe them not to.

I'm pretty sure that's how North Korea makes most of it's income.

"Claiming" is the operative term. If they could, they'd be doing it.

You seem to be assuming they aren't.

Yes.

Most visible in the P-wave amplitude.  

Thanks a bunch.  I have a feeling you have just ruined a perfectly good sick day whereby I shall now spend most of the morning 5 tabs deep in wikipedia.

Just be glad that the folks in the Seismic Shop don't alert you to a sortie you're flying in a few hours based on those damned P-Waves. 

Turns out you are responsible for the first 30 seconds of whatever you say when woken from a dead sleep in the middle of the night...

The same advantage the Soviet Union gained from faking the Bomber Gap.
