There were cluster equakes today in Oklahoma between Enid and Oklahoma City.

These are fracking wells (click here) in Oklahoma. Oklahoma City is slightly to the right of center. Enid is slightly northwest of Oklahoma City and just below that huge cluster of well at the border.

There was also one earthquake in Kansas just north of the Oklahoma earthquakes.
