How big was it?

This earthquake released about 0.27 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 1.6 would have released about 32 times as much.

  1. Mineral, Virginia 2011 M 5.8 57,000,000× the energy of this one
  2. Magna, Utah 2020 M 5.7 40,000,000× the energy of this one
  3. Around the size people start to feel M 3.0 3,600× the energy of this one
  4. This earthquake M 0.6 about 0.27 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 5.2 on 2016-06-10 — about 6,900,000 times the energy of this one.

Before 2016, the USGS record lists 13 earthquakes of M5 or more within 50 km; the five largest:

  1. 6.7 The 1918 San Jacinto, California Earthquake · 14 km WNW of this epicentre
  2. 6.0 The 1986 North Palm Springs, California Earthquake · 37 km NNE of this epicentre
  3. 5.5 11km SSE of Big Bear Lake, California · 50 km N of this epicentre
  4. 5.4 20km NNW of Borrego Springs, CA · 46 km SE of this epicentre
  5. 5.3 4km NNE of Desert Hot Springs, CA · 44 km NE 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.
