North-central Arkansas has seen an increase in unconventional resource development and seismicity within the Fayetteville Shale development area (FSDA) since 2009. The FSDA is historically seismically active, and the increase in seismic activity is likely a combination of both natural and induced earthquakes. This study evaluates 296 FSDA earthquakes from the Advanced National Seismic System (ANSS) catalog classifying the events as natural, potentially induced, or likely induced. Induced earthquakes are associated with hydraulic fracturing of production (HFP) wells and the injection of fluids in saltwater disposal (SWD) wells. For the HFP well evaluation, a questionnaire was developed to help classify the earthquakes. In addition, a matched filter analysis provided evidence to raise some HFP event classifications from potentially to likely induced. A catalog of FSDA induced earthquakes was created that can be used to exclude potentially induced earthquakes from the hazard calculation for future U.S. National Seismic Hazard Map updates.
