This was a small earthquake. Shaking like this is often felt indoors nearby and very rarely causes damage. 25 people have reported feeling it to USGS.

How big was it?

This earthquake released about 230 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 3.6 would have released about 32 times as much.

  1. Mineral, Virginia 2011 M 5.8 65,000× the energy of this one
  2. Magna, Utah 2020 M 5.7 46,000× the energy of this one
  3. Around the size people start to feel M 3.0 4.1× the energy of this one
  4. This earthquake M 2.6 about 230 lb of TNT

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.
