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 46 km (29 mi) from the epicentre. In Escondido, 35 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: Aguanga 19 km, intensity II · Julian 29 km, intensity II · Ramona 29 km, intensity II · Anza 31 km, intensity II · San Diego Country Estates 32 km, intensity II · Escondido 35 km, intensity II · Borrego Springs 37 km, intensity II · Temecula 41 km, intensity II. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 1.1 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.2 would have released about 32 times as much.

- Mineral, Virginia 2011 M 5.8 7,200× the energy of this one
- Magna, Utah 2020 M 5.7 5,100× the energy of this one
- This earthquake M 3.2 about 1.1 tons of TNT
- Around the size people start to feel M 3.0 this one released 2.2× 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.
