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 45 km (28 mi) from the epicentre. In Ojai, 20 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: Ojai 20 km, intensity III · Carpinteria 23 km, intensity II · Santa Barbara 33 km, intensity II · Ventura 35 km, intensity II · Santa Paula 39 km, intensity II · Goleta 43 km, intensity II. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 1,800 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.2 would have released about 32 times as much.
