TULSA, Okla. - Earthquakes in Oklahoma have increased in the last few years.

In fact the state is on pace to have the most earthquakes in state history this year.

On Wednesday at the University of Tulsa, about 80 people packed in a room to discuss the relation of hydrofracking and the recent rumbles.

Hydrofracking, or hydraulic fracturing, uses high-pressure water to open up gas deep below the surface.

Geologist Donald Clarke said earthquakes in the state jumped from about 20 per year to 200 in one year.

“It’s like a line just shot way up very dramatically,” said Clarke.

This year he said we could have as many as 400. Although you may not even feel them, numbers prove they're growing in frequency.

“The trend does appear to be tied to deep structural interpretations and those need to be changed and I think people are looking at that right now,” he said.

He suggested the connection between the quakes and hydrofracking needs to be studied more.

“The Prague one has had three conclusions on it that were all very strongly put forward and one of them could be fracking and others being stress fields,” he said.

The 2011 earthquake in Prague was the largest recorded in the state with a 5.7 magnitude. The recent quakes have averaged around 2.6.

Clarke said central Oklahoma appears to be on track to get hit the most.

Not just wells in OK thousands of sites all over the world. Make drilling illegal. Make it illegal to extract petroleum for energy. We can use hemp for an energy source. It's renewable source will provide us with a renewable energy source along with other valuable sources for medicine. STOP GLOBAL SUICIDE

Not an average but the most recent events meter around 3.0 to 4.0 and up. The accumulative effects are yet unknown.

Make drilling illegal. Legalize hemp it can be used as an energy source. Petroleum madness. The largest (5.5) could be felt in Wisconsin
