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 104 km (65 mi) from the epicentre. In Frazier Park, 2 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: Frazier Park 2 km, intensity IV · Arvin 45 km, intensity III · Piru 46 km, intensity III · Lamont 50 km, intensity III · Ojai 50 km, intensity III. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 22 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.

- Mineral, Virginia 2011 M 5.8 340× the energy of this one
- Magna, Utah 2020 M 5.7 240× the energy of this one
- This earthquake M 4.1 about 22 tons of TNT
- Around the size people start to feel M 3.0 this one released 46× 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.
