Earthquake near Barstow Heights, CA

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 10 km (6 mi) from the epicentre. In Barstow Heights, 49 km away, the estimate is intensity I (not felt). 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.

How big was it?

This earthquake released about 6.2 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 2.5 would have released about 32 times as much.

1. Mineral, Virginia 2011 M 5.8 2,500,000× the energy of this one
2. Magna, Utah 2020 M 5.7 1,700,000× the energy of this one
3. Around the size people start to feel M 3.0 150× the energy of this one
4. This earthquake M 1.5 about 6.2 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 4.3 on 2016-02-20 — about 14,000 times the energy of this one.

Before 2016, the USGS record lists 20 earthquakes of M5 or more within 50 km; the five largest:

1. 7.3 The 1992 Landers, California Earthquake · 49 km SSE of this epicentre Jun 28, 1992
2. 7.1 The 1999 Hector Mine, California Earthquake · 32 km E of this epicentre Oct 16, 1999
3. 6.5 The 1947 Manix, California Earthquake · 42 km N of this epicentre Apr 10, 1947
