Here are a few more - so don't comment negatively until you have read about the subject.

Earthquake Outbreak: Arkansas Bans Fracking Operations Inside Thousand-Square-Mile Area | Stuart H. Smith
Scientists study link between fracking and earthquakes | Real Aspen | Roaring Fork Valley News, Guides, and Information
Fracking & earthquakes: an inescapable connection | The Greanville Post

I have read the links and about the subject!
Perhaps I should have said ' Who says so who has a credible opinion worth reading'.
The Greanville Post(What the System doesn't want you to know).A conspiracy site 'focusing on the infotainment world'! I think not.
The Stuart Smith Blog? A lawyer, not a scientist.I think not.
Aspen-first paragraph says,in brief,'large earthquakes in Virginia and Colarado AREN'T typically associated with hydraulic fracturing.
So a 4.5 in the Netherlands probably has nothing to do with fracking, according to one of your sources.
So the ground settles a bit, it often did after mining,no real problem.
