How big was it?

This earthquake released about 3.9 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 2.4 would have released about 32 times as much.

  1. Mineral, Virginia 2011 M 5.8 3,800,000× the energy of this one
  2. Magna, Utah 2020 M 5.7 2,700,000× the energy of this one
  3. Around the size people start to feel M 3.0 240× the energy of this one
  4. This earthquake M 1.4 about 3.9 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.
