{{main|Guy-Greenbrier earthquake swarm}}

Starting on September 20, 2010 (of which the event on February 27, 2011, was the largest, at magnitude 4.7), the area around Guy was plagued by more than 500 earthquakes. The temblors, ranging from 1.8 (barely noticeable) to 4.7 (very obvious), are being investigated by the [[US Geological Survey]] and the Arkansas Oil and Gas Commission. The quakes may be related to the injection of salt and other waste water into deep wells to dispose of the fluid without contaminating surface or ground water.<ref>{{cite news| url=http://us.cnn.com/2010/US/12/23/arkansas.earthquakes/index.html?hpt=T2 | work=CNN | title=Central Arkansas growing weary of relentless tremors | date=December 28, 2010}}</ref><ref>{{cite news |title=A Dot on the Map, Until the Earth Started Shaking |url=https://www.nytimes.com/2011/02/06/us/06earthquake.html?_r=1&hp |quote=But in their sheer numbers, they have been relentless, creating a phenomenon that has come to be called the Guy earthquake swarm. |newspaper=[[New York Times]] |date=February 5, 2011 |access-date=February 5, 2011 |first=Campbell |last=Robertson}}</ref>
