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 54 km (34 mi) from the epicentre. In Coalinga, 24 km away, the estimate is intensity II (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: Coalinga 24 km, intensity II · Avenal 36 km, intensity II · Paso Robles 41 km, intensity II · Huron 46 km, intensity II. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 1.6 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 4,700× the energy of this one
- Magna, Utah 2020 M 5.7 3,300× the energy of this one

- Around the size people start to feel M 3.0 this one released 3.3× 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.
