Even the same aftershock patterns.
Yeah I'm seeing this in nearly every region on the mainland us.
What is interesting is the aftershocks being consistent across those regions. It seems like they are harmonics to the frequency of the wave that clearly is moving across the us.

The only things coming to mind right now would be a large quake to cause the wave to travel the distance we're seeing but what quake?
If you are trying to build a wave though, you do do slowly through offset frequencies. Which is what we appear to be looking at with this.
If there is some device crashing the waves it should be simple to track down the origin given the mesh of sensors.
Ann Arbor, MI was interesting. Aren't there also mil facilities there? There is also a particle collider there, the LHC.
AK and WA have the earliest report and the strongest. Maybe it's offshore to WA because AK is way up there and the registration is nearly identical in time on the two earliest. But to get all the way to the east coast, I don't know
