Good article. It also addresses the disposal of wastes into crustal 
space. I might have jumped to conclusion that it was a fracting/fracking 
issue this time. This could be a disposal issue. I always looked at the 
quality rating 
fromhttp://folkworm.ceri.memphis.edu/recenteqs/Quakes/usb000agbp.html 
focuses of less than 7 km and a quality rating of fair to poor is what I 
use. If a lot of the wave phases are missing there has to be a human 
reason. It is going to get harder to generalize. I understand depths of 
15000ft will come soon.
