This was a minor earthquake. Quakes this small are rarely felt and do not cause damage.
USGS catalogues this as explosion, not an earthquake.
How big was it?
This earthquake released about 30 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 3.0 would have released about 32 times as much.
- Mineral, Virginia 2011 M 5.8 500,000× the energy of this one
- Magna, Utah 2020 M 5.7 350,000× the energy of this one
- Around the size people start to feel M 3.0 32× the energy of this one
- This earthquake M 2.0 about 30 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.
