Mineral, Virginia 2011 M 5.8 180× the energy of this one
Magna, Utah 2020 M 5.7 130× the energy of this one
This earthquake M 4.3 about 43 tons of TNT
Around the size people start to feel M 3.0 this one released 89× 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.
