1. Mineral, Virginia 2011 M 5.8 7,200,000× the energy of this one
2. Magna, Utah 2020 M 5.7 5,100,000× the energy of this one
3. Around the size people start to feel M 3.0 450× the energy of this one
4. This earthquake M 1.2 about 2.1 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.
