2. Magna, Utah 2020 M 5.7 50,000× the energy of this one
3. Around the size people start to feel M 3.0 4.4× the energy of this one
4. This earthquake M 2.6 about 220 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.
