This was a small earthquake. Shaking like this is often felt indoors nearby and very rarely causes damage.
At this magnitude and depth, people at rest would likely notice it out to about 370 km (230 mi) from the epicentre. In Cushing, 18 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: Stroud 12 km, intensity IV · Cushing 18 km, intensity IV · Chandler 27 km, intensity IV · Yale 29 km, intensity III · Perkins 37 km, intensity III · Prague 41 km, intensity III · Stillwater 47 km, intensity III. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 5.4 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.7 would have released about 32 times as much.

- Mineral, Virginia 2011 M 5.8 1,400× the energy of this one
- Magna, Utah 2020 M 5.7 1,000× the energy of this one
- This earthquake M 3.7 about 5.4 tons of TNT
- Around the size people start to feel M 3.0 this one released 11× more
Energy from the Gutenberg–Richter relation (log10E = 1.5M + 4.8), rounded to two figures; bar length is magnitude, which is already a logarithm of energy. Magnitudes of past earthquakes from the USGS catalogue.
For this area
The largest earthquake within 50 km since 2016 was M 5.0 on 2016-11-07 — about 89 times the energy of this one.
Before 2016, the USGS record lists one earthquake of M5 or more within 50 km:
- 5.7 8 km NW of Prague, Oklahoma · 37 km SSW of this epicentre
Since 2016: the QuakeIndex catalogue (US, M1.5+), built from the USGS FDSN event service. Before 2016: USGS ComCat, M5+ from 1900. Distances are between epicentres. This is the record, not a forecast.
