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 65 km (40 mi) from the epicentre. In Salton City, 16 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: Salton City 16 km, intensity III · Borrego Springs 25 km, intensity III · Mecca 38 km, intensity II · Julian 49 km, intensity II. Estimated for each town centre; each link is that town's own record.

How big was it?

This earthquake released about 3.1 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.5 would have released about 32 times as much.

  2. Mineral, Virginia 2011 M 5.8 2,500× the energy of this one
  3. Magna, Utah 2020 M 5.7 1,700× the energy of this one
  4. This earthquake M 3.5 about 3.1 tons of TNT
  5. Around the size people start to feel M 3.0 this one released 6.5× 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.

For this area

The largest earthquake within 50 km since 2016 was M 5.3 on 2021-06-05 — about 370 times the energy of this one.

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

  1. 6.6 The 1942 Fish Creek Mountains, California Earthquake · 41 km SE of this epicentre
  2. 6.6 The 1968 Borrego Mountain, California Earthquake · 6 km S of this epicentre
  3. 6.6 The 1987 Superstition Hills, California Earthquake · 34 km SE of this epicentre
  4. 6.4 The 1954 San Jacinto Fault, California Earthquake · 8 km NNE of this epicentre
  5. 6.2 The 1987 Elmore Ranch, California Earthquake · 33 km ESE 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.
