OKLAHOMA - Many have wondered if the recent earthquakes are man-made events, but now a new study may back those claims up.

We've felt a whole lot of shaking in the past couple months.

Take a look at the quakes we've had in just the last seven days.

It's quickly becoming just one more thing we deal with here in the Sooner State.

But the reason "why" is a hot topic.

We've been rocking and rolling in Oklahoma for the last couple of years, and the numbers show it.

Now, a new study involving Cornell and CU Boulder says the increase in earthquakes in Central Oklahoma is most likely caused by the injection of large amounts of waste-water from oil and gas operations into underground layers of rock.

Before 2008, Oklahoma averaged two earthquakes per year with a magnitude of 3 point zero or greater, according to USGS.

This year between just January 1st and May 2nd Oklahoma has had 145. If you do the math, that's a 40 fold increase in seismic activity.

Researches say this coincides with a boom in hydraulic fracturing.
