There are theoretically ways of cheating the seismic detectors. The test device can be contained in single-use structures that modify the signal that finally reaches the lithosphere. Giant silencers in essence. Until now the tests have been done in stable rock. In softer, more heterogeneous matrix the signal would be different ... a half-step between nominal and "suppressed" detonations. I hear on the news that the Indian high-yield (i.e. fusion) test was probably not a complete success. "Probably"? I suspect that the line between seismic signal and noise is either not very good - or the intelligence folks are being coy. Since I don't know much about seismography, I wouldn't know which. (My instinct is the latter, but hey, I'm an amateur.) In theory a multimegaton test could be synchronized with a major earthquake. That would be like trying to hear someone talk to you while skydiving. But that is very unlikely.
