This was a light earthquake. It is usually felt clearly nearby and can rattle windows and dishes, but damage is uncommon.
At this magnitude and depth, people at rest would likely notice it out to about 671 km (417 mi) from the epicentre. In Snyder, 24 km away, the estimate is intensity V (moderate). 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: Rotan 22 km, intensity V · Snyder 24 km, intensity V. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 170 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 5.7 would have released about 32 times as much.

- Mineral, Virginia 2011 M 5.8 45× the energy of this one
- Magna, Utah 2020 M 5.7 32× the energy of this one
- This earthquake M 4.7 about 170 tons of TNT

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
