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 Hayward, 3 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: Hayward 3 km, intensity III · Castro Valley 6 km, intensity III · Union City 7 km, intensity III · San Lorenzo 8 km, intensity III · Dublin 12 km, intensity III · San Leandro 12 km, intensity III · Fremont 12 km, intensity III · Newark 13 km, intensity III. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 1.4 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 2019-10-15 — about 51 times the energy of this one.
