R evised Date:01 June 2017
ArkansasAlthough this m ap was com piled from digital data that was successfully processed on a com puter system using ESR I ArcGIS 10.x software at the Arkansas Geological Survey (AGS), no warranty, ex pressed or im plied, is m ade by the AGS regarding the unity of the data on any other system , nor shall the act of distribution constitute any such warranty. The AGS does not guarantee this m ap or digital data to be free of errors or assum e liability for interpretations from this m ap or digital data, or decisions based thereon. The views and conclusions contained in this docum ent are those of the authors and should not be interpreted as necessarily representing the official policies, either ex pressed or im plied, of the Arkansas Geological Survey. The depicted earthquakes, faults and delineated seism ic areas/zones are for illustration purposes and m ay or m ay not represent all seism ically active faults and areas or indicate the ex act origin of the earthquakes depicted on this m ap. The nam ed faults/fault system s delineated on this m ap m ay or m ay not correspond with nam ed faults at the surface or in the subsurface that originate from other published sources.
Disclaim er
This m ap illustrates the location and m agnitude of reported earthquakes that have occurred in the central portion of the Fayetteville Shale Play in north-central Arkansas. Earthquake epicenters in the area occur in scattered clusters and swarm s (as delineated on the m ap). The earthquakes depicted on this m ap are derived from the Arkansas Geological Survey (AGS) earthquake catalog. This catalog has been com piled from various sources and publications (given below as references) and includes date, tim e, latitude, longitude, m agnitude or intensity, and depth inform ation. Som e event records m ay contain incom plete data due to their date and/or source. The AGS earthquake catalog is dynam ic and continually updated as event param eters are m odified, new events are added and occasionally past events are deleted. The faults depicted on the m ap represent a series west-to-east, northwest-to-southeast and east-to-northeast-trending subsurface norm al faults. The m ajority of the faults are downthrown to the south and the am ount of displacem ent varies along the length of the fault (but can be up to 2000 feet locally). The nam ed fault system s represent a zone of single and m ultiple low to high-angle faults that typically form an en echelon m ap pattern. In the subsurface, the high-angle faults ex tend from the Precam brian basem ent up to the Mississippian-Pennsylvanian unconform ity while the lower angle faults ex tend from that unconform ity through the Pennsylvanian strata and m ay or m ay not reach the surface. In the Fayetteville Shale Play, the m ajority of the earthquakes appear to originate from the deeper Precam brian basem ent and lower Paleozoic faults; however earthquakes have also occurred along the shallower upper Paleozoic faults.
