At this magnitude and depth, people at rest would likely notice it out to about 73 km (45 mi) from the epicentre. In Enid, 36 km away, the estimate is intensity III (weak). 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: Enid 36 km, intensity III · Caldwell 39 km, intensity III · Blackwell 42 km, intensity II. Estimated for each town centre; each link is that town's own record.
How big was it?
