The other seismic stations that I've seen didn't really pick this up, but it seems to me that this is obviously a nuclear weapon or a large munition explosion. The fact that the wave has such a low frequency at 0141 UTC from a relatively clean seismometer makes it obvious that this was a sudden instanteneous release of energy (for those who are experienced in physics, this wavelength shouldn't be surprising considering that the Laplace transform of a Dirac Delta function is a decaying exponential--and the frequency does appear to die off exponentially). This record is the smoking gun for me.
This is amazing...wake up early to find CNN and EVEN MSNBC covering this live...but FOX has a reply of Bulls N Bears?!?! WTH is WRONG with them?
NOOOOOOOO!!!! Not Laplace! Anything but that!!! (Nightmares from Process Control)
