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 50 km (31 mi) from the epicentre. In Beaumont, 4 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: Beaumont 4 km, intensity III · Yucaipa 10 km, intensity III · Banning 10 km, intensity III · Mentone 18 km, intensity II · San Jacinto 20 km, intensity II · Redlands 21 km, intensity II · Moreno Valley 24 km, intensity II · Hemet 24 km, intensity II. Estimated for each town centre; each link is that town's own record.

How big was it?

This earthquake released about 1.3 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.3 would have released about 32 times as much.

Northridge, California 1994 M 6.7 130,000× the energy of this one
Mineral, Virginia 2011 M 5.8 5,800× the energy of this one
Magna, Utah 2020 M 5.7 4,100× the energy of this one
This earthquake M 3.3 about 1.3 tons of TNT
Around the size people start to feel M 3.0 this one released 2.7× 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.

For this area

The largest earthquake within 50 km since 2016 was M 4.5 on 2018-05-08 — about 63 times the energy of this one.

Before 2016, the USGS record lists 24 earthquakes of M5 or more within 50 km; the five largest:

6.7 The 1918 San Jacinto, California Earthquake · 23 km S of this epicentre Apr 21, 1918
6.3 The 1992 Big Bear, California Earthquake · 30 km NNE of this epicentre Jun 28, 1992
6.2 3 km SE of San Bernardino, California · 29 km WNW of this epicentre Jul 23, 1923
6.0 The 1910 Lake Elsinore, California Earthquake · 49 km SW of this epicentre May 15, 1910
6.0 The 1986 North Palm Springs, California Earthquake · 34 km E of this epicentre Jul 8, 1986

Since 2016: the QuakeIndex catalogue (US, M1.5+), built from the USGS FDSN event service. Before 2016: USGS ComCat, M5+ from 1900. Distances are between epicentres. This is the record, not a forecast.
