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 33 km (21 mi) from the epicentre. In Cabazon, 12 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: Morongo Valley 15 km, intensity II · Banning 16 km, intensity II · Desert Hot Springs 23 km, intensity II · Beaumont 24 km, intensity II · Yucaipa 28 km, intensity II · Palm Springs 28 km, intensity II · Big Bear City 28 km, intensity II · Big Bear Lake 29 km, intensity II. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 920 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.0 would have released about 32 times as much.

- This earthquake M 3.0 about 920 lb of TNT
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.
