How big was it?

This earthquake released about 150 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 5.7 would have released about 32 times as much.

Northridge, California 1994 M 6.7 1,100× the energy of this one
Mineral, Virginia 2011 M 5.8 51× the energy of this one
Magna, Utah 2020 M 5.7 36× the energy of this one
This earthquake M 4.7 about 150 tons of TNT
Around the size people start to feel M 3.0 this one released 310× 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.
