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 21 km (13 mi) from the epicentre. In San Jacinto, 3 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: San Jacinto 3 km, intensity III · Valle Vista 6 km, intensity II · Hemet 7 km, intensity II · Banning 15 km, intensity II · Beaumont 16 km, intensity II · Idyllwild 20 km, intensity II. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 220 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 3.6 would have released about 32 times as much.
- Mineral, Virginia 2011 M 5.8 70,000× the energy of this one
- Magna, Utah 2020 M 5.7 50,000× the energy of this one
- Around the size people start to feel M 3.0 4.4× the energy of this one
- This earthquake M 2.6 about 220 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.
