This was a small earthquake. Shaking like this is often felt indoors nearby and very rarely causes damage. 136 people have reported feeling it to USGS.

How big was it?

This earthquake released about 2.2 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.4 would have released about 32 times as much.

  2. Mineral, Virginia 2011 M 5.8 3,500× the energy of this one
  3. Magna, Utah 2020 M 5.7 2,500× the energy of this one
  4. This earthquake M 3.4 about 2.2 tons of TNT
  5. Around the size people start to feel M 3.0 this one released 4.6× 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.
