Thanks Brian,
But, to tell a trend, you would have to limit the numbers to completeness: maybe M2.5+ or M3+. Logically, with fracking and the quakes the last few years, there would be some funding to install local networks of seismometers. Someone must know whether it is fracking or injection, because the quakes would be spatially-associated with the injection wells. Or, could fracking and especially injection wells trigger quakes and these quakes trigger other quakes more remote from the injection?
The quakes the past week in Oklahoma were shallow: less than 5 km depth, except a bunch of them were exactly 5.0 km, so likely assigned to that depth in the location program.
