This was a small earthquake. Shaking like this is often felt indoors nearby and very rarely causes damage. 1 person has reported feeling it to USGS.

How big was it?

This earthquake released about 280 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.

Mineral, Virginia 2011 M 5.8 53,000× the energy of this one
Magna, Utah 2020 M 5.7 38,000× the energy of this one
Around the size people start to feel M 3.0 3.3× the energy of this one
This earthquake M 2.6 about 280 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.
