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 95 km (59 mi) from the epicentre. In Kettleman City, 9 km away, the estimate is intensity IV (light). 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: Kettleman City 9 km, intensity IV · Avenal 13 km, intensity III · Huron 31 km, intensity III · Coalinga 39 km, intensity III · Corcoran 45 km, intensity III · Lemoore 46 km, intensity III · Lost Hills 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 14 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 5.0 would have released about 32 times as much.

  2. Mineral, Virginia 2011 M 5.8 540× the energy of this one
  3. Magna, Utah 2020 M 5.7 380× the energy of this one
  4. This earthquake M 4.0 about 14 tons of TNT
  5. Around the size people start to feel M 3.0 this one released 30× 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 since 2016 was M 4.3 on 2019-12-17 — about 2.9 times the energy of this one.

Before 2016, the USGS record lists 16 earthquakes of M5 or more within 50 km; the five largest:

  1. 6.7 The 1983 Coalinga, California Earthquake · 43 km NW of this epicentre
  2. 6.5 1922 Parkfield, California Earthquake · 30 km SW of this epicentre
  3. 6.4 1901 Parkfield, California Earthquake · 44 km W of this epicentre
  4. 6.0 2004 Parkfield, California Earthquake · 34 km WSW of this epicentre
  5. 5.6 8 km SW of Huron, California · 26 km NNW 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.
