Did an 8.6 Earthquake just happen in China, or is this a co-ordinated internet hoax?

Courtesy of Above Top Secret, but this has been floating around several overlapping websites this evening. Nothing, NOTHING so far on USGS, or CNN, or any other mainstream news sites. So, what happened?

Maybe this is nothing. We'll know for sure in the coming days.

UPDATE: There is no update. The location of this.. event.. was mountainous and remote, but remote by Chinese standards would still be populated. What caused multiple sites to register this event as an 8.6 EQ, and then it not be so? Huh..
