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 61 km (38 mi) from the epicentre. In Indio, 17 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: Indio 17 km, intensity III · Thousand Palms 19 km, intensity III · Coachella 21 km, intensity III · Palm Desert 23 km, intensity III · La Quinta 25 km, intensity II · Cathedral City 27 km, intensity II · Desert Hot Springs 30 km, intensity II · Joshua Tree 32 km, intensity II. Estimated for each town centre; each link is that town's own record.

How big was it?

This earthquake released about 2.4 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 3,100× the energy of this one
  3. Magna, Utah 2020 M 5.7 2,200× the energy of this one
  4. This earthquake M 3.5 about 2.4 tons of TNT
  5. Around the size people start to feel M 3.0 this one released 5.1× 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 4.2 on 2019-07-22 — about 12 times the energy of this one.

Before 2016, the USGS record lists 23 earthquakes of M5 or more within 50 km; the five largest:

  1. 7.3 The 1992 Landers, California Earthquake · 43 km NNW of this epicentre
  2. 6.1 The 1992 Joshua Tree, California Earthquake · 15 km NW of this epicentre
  3. 6.0 The 1948 Desert Hot Springs, California Earthquake · 18 km NW of this epicentre
  4. 6.0 The 1986 North Palm Springs, California Earthquake · 41 km WNW of this epicentre
  5. 5.8 3km NE of Yucca Valley, California · 35 km NNW 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.
