- Mineral, Virginia 2011 M 5.8 92,000× the energy of this one
- Magna, Utah 2020 M 5.7 65,000× the energy of this one
- Around the size people start to feel M 3.0 5.8× the energy of this one
- This earthquake M 2.5 about 160 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.
