Earthquake near Desert Hot Springs, CA

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 59 km (37 mi) from the epicentre. In Desert Hot Springs, 11 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: Desert Hot Springs 11 km, intensity III · Yucca Valley 14 km, intensity III · Joshua Tree 17 km, intensity III · Morongo Valley 19 km, intensity III · Thousand Palms 19 km, intensity III · Palm Springs 23 km, intensity III · Cathedral City 25 km, intensity II · Palm Desert 30 km, intensity II. Estimated for each town centre; each link is that town's own record.

How big was it?

This earthquake released about 2.1 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.4 would have released about 32 times as much.

2. Mineral, Virginia 2011 M 5.8 3,600× the energy of this one
3. Magna, Utah 2020 M 5.7 2,500× the energy of this one
4. This earthquake M 3.4 about 2.1 tons of TNT
5. Around the size people start to feel M 3.0 this one released 4.4× 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.
