After increasing rapidly over the past three years, the pace of earthquakes in Oklahoma held steady in 2014 at a rate higher than California and far higher than the historic average in Oklahoma.

Oklahoma experienced 567 earthquakes of magnitude 3.0 or greater in 2014, up from 209 in 2013. The state had averaged about 40 a year for the previous five years and less than five a year before that. …

“It looks like we’re at about the same rate now as we were last year at this point,” Oklahoma Geological Society seismologist Austin Holland said. “We’re continuing to see a high rate, but it looks like a steady rate at this point.”

While researchers and policymakers are pleased the rate has not continued to grow, they are still working to better understand what the state is experiencing.

“We took it as good news, but there are so many unknowns in this,” said Michael Teague, Oklahoma energy and environment secretary. “Until we unravel more of this, I don’t know what to make of the snapshots of data we have now.”
