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 50 km (31 mi) from the epicentre. In Gilroy, 10 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: Gilroy 10 km, intensity III · Hollister 16 km, intensity III · Morgan Hill 24 km, intensity II · Watsonville 27 km, intensity II · Prunedale 29 km, intensity II · Salinas 38 km, intensity II · Capitola 44 km, intensity II · Live Oak 46 km, intensity II. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 1.2 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.
