The Guy Earthquake Swarms


136283725
A small community just north of Little Rock, Guy wasn’t accustomed to drawing national attention. That all changed in 2010, when a series of relatively minor earthquakes shook the town. The first swarm struck in fall 2010, with most quakes registering under 2.0 on the Richter scale, meaning not everyone in town may have felt or even noticed the shaking. However, the swarms continued over the next two years and increased in magnitude, with one reaching as high as 4.7 in February 2011.
With the trembling becoming more noticeable, residents began to wonder if the quakes were a result of hydraulic fracturing techniques being used to drill for oil and gas in the area. The Arkansas Geological Survey was called out to investigate, and while the group noted that there is some evidence that fracking can cause minor earthquakes, they found no link between the drilling and these particular swarms.
Earthquake swarms aren’t entirely unusual in Arkansas. The state’s had a handful of them before, but none have reached the magnitude of those in Guy. Through 2013, over 500 quakes have rocked the town. As northeast corner of Arkansas was home to one of the country’s most violent swarms—the 1811-12 New Madrid earthquakes—the seemingly endless quakes have left some residents particularly on edge.
