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 271 km (168 mi) from the epicentre. In Luther, 3 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: Luther 3 km, intensity IV · Choctaw 21 km, intensity III · Chandler 26 km, intensity III · Edmond 28 km, intensity III · Midwest City 32 km, intensity III · Langston 32 km, intensity III · Guthrie 33 km, intensity III · Perkins 36 km, intensity III. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 1.9 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.4 would have released about 32 times as much.

- Mineral, Virginia 2011 M 5.8 4,000× the energy of this one
- Magna, Utah 2020 M 5.7 2,800× the energy of this one
- This earthquake M 3.4 about 1.9 tons of TNT
- Around the size people start to feel M 3.0 this one released 4× 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 4.2 on 2016-04-07 — about 16 times the energy of this one.
