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 103 km (64 mi) from the epicentre. In Paradise, 40 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: Chester 31 km, intensity III · Greenville 33 km, intensity III · East Quincy 37 km, intensity III · Paradise 40 km, intensity III · Westwood 40 km, intensity III. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 20 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 5.1 would have released about 32 times as much.

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 5.5 on 2023-05-11 — about 130 times the energy of this one.
Before 2016, the USGS record lists 2 earthquakes of M5 or more within 50 km:
