Not a warning. An alert comes after USGS publishes a quake, usually minutes after the shaking. For early warning use ShakeAlert, through your phone's Wireless Emergency Alerts or the MyShake app.
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 41 km (25 mi) from the epicentre. In Cabazon, 5 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: Banning 9 km, intensity III · Beaumont 18 km, intensity II · Morongo Valley 21 km, intensity II · Yucaipa 25 km, intensity II · San Jacinto 25 km, intensity II · Idyllwild 25 km, intensity II · Valle Vista 26 km, intensity II · Desert Hot Springs 26 km, intensity II. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 1,400 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.1 would have released about 32 times as much.

- Mineral, Virginia 2011 M 5.8 10,000× the energy of this one
- Magna, Utah 2020 M 5.7 7,400× the energy of this one
- This earthquake M 3.1 about 1,400 lb of TNT
- Around the size people start to feel M 3.0 this one released 1.5× more
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.
