This was a minor earthquake. Quakes this small are rarely felt and do not cause damage. 20 people have reported feeling it to USGS.

How big was it?

This earthquake released about 25 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 3.0 would have released about 32 times as much.

Mineral, Virginia 2011 M 5.8 600,000× the energy of this one
Magna, Utah 2020 M 5.7 420,000× the energy of this one
Around the size people start to feel M 3.0 38× the energy of this one
This earthquake M 1.9 about 25 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.
