This was a light earthquake. It is usually felt clearly nearby and can rattle windows and dishes, but damage is uncommon. 6 people have reported feeling it to USGS.

How big was it?

This earthquake released about 47 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 5.3 would have released about 32 times as much.

  2. Mineral, Virginia 2011 M 5.8 160× the energy of this one
  3. Magna, Utah 2020 M 5.7 110× the energy of this one
  4. This earthquake M 4.3 about 47 tons of TNT
  5. Around the size people start to feel M 3.0 this one released 99× 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.
