This was a small earthquake. Shaking like this is often felt indoors nearby and very rarely causes damage.

How big was it?

This earthquake released about 1,700 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.2 would have released about 32 times as much.

  1. Northridge, California 1994 M 6.7 200,000× the energy of this one
  2. Mineral, Virginia 2011 M 5.8 8,800× the energy of this one
  3. Magna, Utah 2020 M 5.7 6,200× the energy of this one
  4. This earthquake M 3.2 about 1,700 lb of TNT
  5. Around the size people start to feel M 3.0 this one released 1.8× 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.
