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 35 km (22 mi) from the epicentre. In Glen Avon, 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: Pedley 7 km, intensity III · Fontana 9 km, intensity III · Eastvale 10 km, intensity III · Rubidoux 10 km, intensity III · Rancho Cucamonga 12 km, intensity III · Norco 12 km, intensity III · Riverside 13 km, intensity III · Ontario 14 km, intensity III. Estimated for each town centre; each link is that town's own record.

How big was it?

This earthquake released about 860 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.

  2. Mineral, Virginia 2011 M 5.8 18,000× the energy of this one
  3. Magna, Utah 2020 M 5.7 12,000× the energy of this one
  4. This earthquake M 3.0 about 860 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.

For this area

The largest earthquake within 50 km since 2016 was M 4.4 on 2018-08-29 — about 130 times the energy of this one.

Before 2016, the USGS record lists 11 earthquakes of M5 or more within 50 km; the five largest:

  1. 6.2 3 km SE of San Bernardino, California · 23 km ENE of this epicentre
  2. 6.0 The 1910 Lake Elsinore, California Earthquake · 38 km SSE of this epicentre
  3. 5.6 7km ENE of Running Springs, CA · 48 km ENE of this epicentre
  4. 5.5 The 1990 Upland, California Earthquake · 22 km NW of this epicentre
  5. 5.4 5km S of Chino Hills, CA · 26 km WSW of this epicentre

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.
