How big was it?

This earthquake released about 2.9 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.5 would have released about 32 times as much.

  2. Mineral, Virginia 2011 M 5.8 2,600× the energy of this one
  3. Magna, Utah 2020 M 5.7 1,900× the energy of this one
  4. This earthquake M 3.5 about 2.9 tons of TNT
  5. Around the size people start to feel M 3.0 this one released 6× 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.
