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 110 km (68 mi) from the epicentre. In Cloverdale, 12 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: Cloverdale 12 km, intensity IV · Cobb 14 km, intensity IV · Lakeport 24 km, intensity III · Healdsburg 25 km, intensity III · Clearlake 26 km, intensity III · Windsor 32 km, intensity III · Upper Lake 37 km, intensity III · Calistoga 38 km, intensity III. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 27 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 5.8 280× the energy of this one
- Magna, Utah 2020 M 5.7 200× the energy of this one

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.
For this area
The largest earthquake within 50 km since 2016 was M 5.0 on 2016-12-14 — about 18 times the energy of this one.
Before 2016, the USGS record lists one earthquake of M5 or more within 50 km:
- 5.2 6 km ESE of Talmage, California · 37 km NNW of this epicentre
Since 2016: the QuakeIndex catalogue (US, M1.5+), built from the USGS FDSN event service. Before 2016: USGS ComCat, M5+ from 1900. Distances are between epicentres. This is the record, not a forecast.
