This was a light earthquake. It is usually felt clearly nearby and can rattle windows and dishes, but damage is uncommon.
How big was it?
This earthquake released about 21 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 5.1 would have released about 32 times as much.
- Northridge, California 1994 M 6.7 7,900× the energy of this one
- Mineral, Virginia 2011 M 5.8 350× the energy of this one
- Magna, Utah 2020 M 5.7 250× the energy of this one
- This earthquake M 4.1 about 21 tons of TNT
- Around the size people start to feel M 3.0 this one released 45× 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.
