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 108 km (67 mi) from the epicentre. In Dollar Point, 10 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: Sunnyside-Tahoe City 12 km, intensity IV · Tahoe Vista 13 km, intensity IV · South Lake Tahoe 21 km, intensity III · Carson City 23 km, intensity III · Truckee 26 km, intensity III · Gardnerville Ranchos 36 km, intensity III · Reno 49 km, intensity III. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 25 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 5.2 would have released about 32 times as much.

- Mineral, Virginia 2011 M 5.8 300× the energy of this one
- Magna, Utah 2020 M 5.7 210× the energy of this one
- This earthquake M 4.2 about 25 tons of TNT
- Around the size people start to feel M 3.0 this one released 53× 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.
