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 54 km (34 mi) from the epicentre. In Redding, 40 km away, the estimate is intensity II (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: Shingletown 12 km, intensity III · Anderson 28 km, intensity II · Red Bluff 34 km, intensity II · Redding 40 km, intensity II · Shasta Lake 45 km, intensity II. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 1.7 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.4 would have released about 32 times as much.
