After a 4.2 magnitude earthquake rumbled through Michigan this weekend, Twitter speculation ran rampant that fracking was to blame.

Not so fast, say the state’s top geologists:

"I am extremely confident there is no connection," said Hal Fitch, a geologist who is director of the Michigan Department of Environmental Quality's Office of Oil, Gas, and Minerals.

That opinion is echoed by David Barnes, professor of geosciences at Western Michigan University.

"I'm as certain as a scientist can be" that there is no connection, Barnes said.

The U.S. Geological Survey has also reported that “the earthquake is not related to any fracking going on in the state of Michigan.”

As IWF notes in its recent policy focus, fracking-induced earthquakes are extraordinarily uncommon. One leading geologist reports that of all the fracking sites worldwide, he’s aware of only about a dozen instances where the process has triggered seismic activity.

The ones recently charted in Ohio occurred in the perfect circumstances, right on top of an existing, ripe fault line. But that wasn’t the case in Michigan:

"The nearest hydraulic fracturing activity is more than 50 miles away and took place several years ago," Fitch said.

The closest oil and gas development to the quake epicenter is about three miles southeast of the epicenter of the earthquake, Fitch said.

The U.S. Geological Survey has placed the quake epicenter along 34th Street just north of East Q Street in the Kalamazoo County community of Scotts. The new oil wells are on Pease Farm off East R Avenue.

"Three producible wells and one dry hole have been drilled in the field, all within the past 18 months," Fitch said.  "None used hydraulic fracturing.  There are no injection wells in the field."

Of course, that didn’t stop Michigan’s Committee to Ban Fracking, which seeks to shut down energy exploration statewide, from making the most of the quake. On Saturday, it retweeted the Kalamazoo Gazette’s live coverage, adding “Lets #banfracking Michigan!”

But Michigan is home to more than 12,000 wells, and though its oil and gas sector remains underdeveloped, its residents still meet around a fifth of their natural gas needs from in-state.

With that in mind, expecting that policy decisions be grounded in sound science, not sensationalistic reactions, is hardly earth-shaking.
