  5. Mineral, Virginia 2011 M 5.8 this one released 2× more
  6. Magna, Utah 2020 M 5.7 this one released 2.8× 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.
