Chicago gets tiny earthquake


“We’re still working on that. That’s what puts the seismologists through school,” Larson said.

I just put this up for that quote!  Other than that, this is about as minor as you can get.

I wonder if there is a small fault line there, or if this has to do with resurgence of land post ice age?

These are at the level of what we call 'frost quakes', which are random little things brought on by cold weather. For some, you can visit the site and see a rock 'pop up'. For this, the existing seismic coverage may only locate it to within many km. You need people to hear it.

Could be deeper, and could be injection, but we'll have to wait for that. :)
