- Northridge, California 1994 M 6.7 2,900× the energy of this one
- Mineral, Virginia 2011 M 5.8 130× the energy of this one
- Magna, Utah 2020 M 5.7 92× the energy of this one
- This earthquake M 4.4 about 58 tons of TNT
- Around the size people start to feel M 3.0 this one released 120× 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.
