This was a minor earthquake. Quakes this small are rarely felt and do not cause damage.
At this magnitude and depth, people at rest would likely notice it out to about 9 km (6 mi) from the epicentre. In Redlands, 3 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: Redlands 3 km, intensity II · Mentone 7 km, intensity II · Loma Linda 7 km, intensity II. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 28 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 3.0 would have released about 32 times as much.
- Mineral, Virginia 2011 M 5.8 540,000× the energy of this one
- Magna, Utah 2020 M 5.7 380,000× the energy of this one
- Around the size people start to feel M 3.0 34× the energy of this one
- This earthquake M 2.0 about 28 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.
