This was a minor earthquake. Quakes this small are rarely felt and do not cause damage.

How big was it?

This earthquake released about 1.7 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 2.2 would have released about 32 times as much.

  1. Mineral, Virginia 2011 M 5.8 9,100,000× the energy of this one
  2. Magna, Utah 2020 M 5.7 6,500,000× the energy of this one
  3. Around the size people start to feel M 3.0 580× the energy of this one
  4. This earthquake M 1.2 about 1.7 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.
