This was a light earthquake. It is usually felt clearly nearby and can rattle windows and dishes, but damage is uncommon.

At this magnitude and depth, people at rest would likely notice it out to about 179 km (111 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: Calexico 41 km, intensity III · Holtville 46 km, intensity III. Estimated for each town centre; each link is that town's own record.

How big was it?

This earthquake released about 320 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 5.9 would have released about 32 times as much.

  2. Mineral, Virginia 2011 M 5.8 23× the energy of this one
  3. Magna, Utah 2020 M 5.7 17× the energy of this one
  4. This earthquake M 4.9 about 320 tons of TNT
  5. Around the size people start to feel M 3.0 this one released 680× 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 in our catalogue was M 4.9 on 2024-05-12.

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.
