At this magnitude and depth, people at rest would likely notice it out to about 271 km (168 mi) from the epicentre. In Wilson, 12 km away, the estimate is intensity IV (light). Estimated from magnitude, depth and distance with the intensity equation USGS Did You Feel It? uses; felt reports, where there are any, are the measurement.
Likely felt in: Healdton 21 km, intensity III · Ardmore 28 km, intensity III. Estimated for each town centre; each link is that town's own record.
