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 14 km (9 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: Redondo Beach in town, intensity II · Manhattan Beach 4 km, intensity II · Torrance 6 km, intensity II · Palos Verdes Estates 6 km, intensity II · Lawndale 6 km, intensity II · Hawthorne 8 km, intensity II · Gardena 9 km, intensity II · Carson 11 km, intensity II. Estimated for each town centre; each link is that town's own record.

How big was it?

This earthquake released about 36 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 3.0 would have released about 32 times as much.

  1. Mineral, Virginia 2011 M 5.8 420,000× the energy of this one
  2. Magna, Utah 2020 M 5.7 300,000× the energy of this one
  3. Around the size people start to feel M 3.0 27× the energy of this one
  4. This earthquake M 2.0 about 36 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

No earthquake of M4 or more has been recorded within 50 km since our catalogue begins in 2016.

Before 2016, the USGS record lists 15 earthquakes of M5 or more within 50 km; the five largest:

  1. 6.7 Northridge, California, earthquake · 42 km NNW of this epicentre
  2. 6.4 The 1933 Long Beach, California Earthquake · 44 km ESE of this epicentre
  3. 5.9 The 1987 Whittier Narrows, California Earthquake · 37 km NE of this epicentre
  4. 5.9 1km ENE of Granada Hills, California · 48 km N of this epicentre
  5. 5.3 2 km SSW of Santa Monica, California · 19 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.
