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 53 km (33 mi) from the epicentre. In Kenwood, 6 km away, the estimate is intensity III (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: Kenwood 6 km, intensity III · Rohnert Park 9 km, intensity III · Santa Rosa 12 km, intensity III · Agua Caliente 12 km, intensity III · Petaluma 17 km, intensity III · Calistoga 22 km, intensity III · Angwin 26 km, intensity II · Windsor 26 km, intensity II. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 1.5 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.

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 4.5 on 2023-06-03 — about 48 times the energy of this one.
