The Oklahoma quakes get mentioned here from time to time, generally in the context of concerns about fracking. But I can't recall a swarm in which they were coming one after the other for an entire day. Does anybody have any clue as to what is really going on?

1. Do you not think it is from the

fracking and injection wells?

2. OK has a history of quakes but they have increased since '09,

and I doubt it's a coincidence. iirc it's the injection wells that look like the most likely cause.

3. Any damage? nt

4. The XL Pipeline runs through this cluster.

That should go well.
