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 234 km (145 mi) from the epicentre. In Stillwater, 39 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: Chandler 15 km, intensity III · Stroud 16 km, intensity III · Cushing 19 km, intensity III · Perkins 26 km, intensity III · Yale 34 km, intensity III · Luther 39 km, intensity III · Prague 39 km, intensity III · Stillwater 39 km, intensity III. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 1.3 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.3 would have released about 32 times as much.

- Mineral, Virginia 2011 M 5.8 5,600× the energy of this one
- Magna, Utah 2020 M 5.7 4,000× the energy of this one
- This earthquake M 3.3 about 1.3 tons of TNT
- Around the size people start to feel M 3.0 this one released 2.8× 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
No earthquake of M4 or more has been recorded within 50 km since our catalogue begins in 2016.
