This was a minor earthquake. Quakes this small are rarely felt and do not cause damage. 1 person has reported feeling it to USGS.
USGS catalogues this as explosion, not an earthquake.
How big was it?
This earthquake released about 24 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 2.9 would have released about 32 times as much.
- Mineral, Virginia 2011 M 5.8 640,000× the energy of this one
- Magna, Utah 2020 M 5.7 450,000× the energy of this one
- Around the size people start to feel M 3.0 40× the energy of this one
- This earthquake M 1.9 about 24 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.
