This was a moderate earthquake. Shaking at this size can damage poorly built structures close to the epicentre.
At this magnitude and depth, people at rest would likely notice it out to about 219 km (136 mi) from the epicentre. In Julian, 5 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: Julian 5 km, intensity V · San Diego Country Estates 18 km, intensity IV · Pine Valley 25 km, intensity IV · Ramona 25 km, intensity IV · Alpine 27 km, intensity IV · Borrego Springs 32 km, intensity IV · Escondido 47 km, intensity IV · Campo 49 km, intensity IV. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 980 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 6.2 would have released about 32 times as much.

- Mineral, Virginia 2011 M 5.8 7.7× the energy of this one
- Magna, Utah 2020 M 5.7 5.4× the energy of this one
- This earthquake M 5.2 about 980 tons of TNT
- Around the size people start to feel M 3.0 this one released 2,100× 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.
