I'm more lax about reading journals than I really should be, but I do subscribe to the paper version of JGR. I received my copy of the November issue (scientific journals have a tendency to be late) this morning, and on a quick flip through it , I noticed the following articles:
Hearn, Thomas M.; Wang, Suyun; Ni, James F.; Xu, Zhonghuai; Yu, Yanxiang; Zhang, Xiaodong, "Uppermost mantle velocities beneath China and surrounding regions"
Liang, Chuntao; Song, Xiaodong; Huang, Jinli, "Tomographic inversion of Pn travel times in China"
So what's odd about that? Well, they're almost the same study -- two independent groups of researchers, applying more or less the same method to more or less the same data set. And, of course, getting remarkably similar results. So how'd they end up in the same issue? I have no idea, but my best guess would be that both were in the pipe at the same time, and rather than try to determine priority, the editor decided to slot them in together.
I must say, it's nice to see a repeatable experiment in geophysics.
If you want more repeatable experiments, you need to use more nukes and make your own earthquakes.
