This was a minor earthquake. Quakes this small are rarely felt and do not cause damage.

At this magnitude and depth it was probably too small to be felt, even directly above it. 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.

Earthquakes near other towns within 30 km: Desert Shores, Salton City, Oasis, Borrego Springs.

How big was it?

This earthquake released about 0.75 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 1.9 would have released about 32 times as much.

  1. Mineral, Virginia 2011 M 5.8 20,000,000× the energy of this one
  2. Magna, Utah 2020 M 5.7 14,000,000× the energy of this one
  3. Around the size people start to feel M 3.0 1,300× the energy of this one
  4. This earthquake M 0.9 about 0.75 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 5.2 on 2025-04-14 — about 2,600,000 times the energy of this one.

Before 2016, the USGS record lists 19 earthquakes of M5 or more within 50 km; the five largest:

  1. 6.6 The 1942 Fish Creek Mountains, California Earthquake · 49 km SE of this epicentre
  2. 6.6 The 1968 Borrego Mountain, California Earthquake · 13 km SSE of this epicentre
  3. 6.6 The 1987 Superstition Hills, California Earthquake · 42 km SE of this epicentre
  4. 6.4 The 1954 San Jacinto Fault, California Earthquake · 7 km E of this epicentre
  5. 6.2 The 1987 Elmore Ranch, California Earthquake · 41 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.
