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 1,900 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.
- Northridge, California 1994 M 6.7 180,000× the energy of this one
- Mineral, Virginia 2011 M 5.8 7,900× the energy of this one
- Magna, Utah 2020 M 5.7 5,600× the energy of this one
- This earthquake M 3.2 about 1,900 lb of TNT
- Around the size people start to feel M 3.0 this one released 2× 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.
