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 6 km (4 mi) from the epicentre. 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: El Centro in town, intensity II. Estimated for each town centre; each link is that town's own record.

How big was it?

This earthquake released about 13 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 2.8 would have released about 32 times as much.

  1. Mineral, Virginia 2011 M 5.8 1,100,000× the energy of this one
  2. Magna, Utah 2020 M 5.7 810,000× the energy of this one
  3. Around the size people start to feel M 3.0 72× the energy of this one
  4. This earthquake M 1.8 about 13 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 4.0 on 2016-07-31 — about 2,500 times the energy of this one.

Before 2016, the USGS record lists 41 earthquakes of M5 or more within 50 km; the five largest:

  1. 6.9 The 1940 Imperial Valley, California Earthquake · 17 km ENE of this epicentre
  2. 6.6 The 1942 Fish Creek Mountains, California Earthquake · 30 km NW of this epicentre
  3. 6.6 The 1987 Superstition Hills, California Earthquake · 38 km NW of this epicentre
  4. 6.4 The 1979 Imperial Valley Earthquake, California-Baja California · 23 km SE of this epicentre
  5. 6.3 The 1906 Imperial Valley, California Earthquake · 13 km NNE 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.
