February might be Earthquake Awareness Month for much of the Midwest, but in one tiny Arkansas town, the consciousness-raising started months ago.

Residents of Guy, Arkansas, have been weathering a swarm of low-magnitude earthquakes since early fall. While the phenomenon has done wonders to increase quake safety knowledge, there are no firm answers as to what’s behind the shake-up.

Some see the mini-quakes as nothing more than an oddity of nature, citing a history of nearby swarms, according to the New York Times. Others are betting it’s caused by increased drilling for natural gas in the area. The safe money might be on both.

“What you could be looking at is a case where the strain was already there,” Arkansas Geological Survey’s Scott Ausbrooks told the Times, explaining why natural swarms don’t rule out a drilling link. “You’d be fast-forwarding the clock.”

The AGS has been keeping an eye on earthquake data since two local drilling sites opened last summer, according to the Times. Although Ausbrooks doesn't suspect the drilling caused the earthquakes, the AGS hasn’t “ruled out a connection to…salt water disposal wells, ” he said in a statement to CNN.

Drilling operations use a technique known as using hydraulic fracturing, or fracking, to get at the good stuff in the ground. That means injecting water, sand, and chemicals deep into the earth to create fractures that free trapped gas. Waste from the process is often re-injected into deep disposal wells. Both injections can stress Earth’s crust and, over time, create small man-made earthquakes, according to the United States Geological Survey.

Drilling has been implicated in atypical earthquakes from Texas to Australia. Still, the industries that send water deep beneath Earth’s surface—including geothermal energy production, coal mining, and proposed carbon sequestration schemes—are skeptical they're behind the shaking. This is understandable in the case of Guy, where at least two similar local swarms occurred before drilling was prevalent, according to the Times.

“We’ve found no causal connection,” Charles Morgan, a lawyer representing Poseidon Energy Services, told the Times. “The evidence is anecdotal at best.”

The question comes down to how the story will end. Perhaps there’s no harm in the small, barely-felt quakes shivering through Guy, even if they are human-induced. A Department of Energy Workshop on Induced Seismicity seemed to come to the conclusion that the public just needs to be reassured so that earthquake-causing technologies can fulfill their “full potential.” But others fear that if smaller swarm quakes go unheeded, they’ll eventually lead to bigger quakes—often in areas where both people and the built environment are unprepared for them. The folks in Guy are just as divided, sometimes within families.

"My wife wants to buy earthquake insurance,” Mayor Sam Higdon told CNN. “I'm trying to talk her out of it."
