This earthquake released about 5.9 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.7 would have released about 32 times as much.

Northridge, California 1994 M 6.7 29,000× the energy of this one
Mineral, Virginia 2011 M 5.8 1,300× the energy of this one
Magna, Utah 2020 M 5.7 900× the energy of this one
This earthquake M 3.7 about 5.9 tons of TNT
Around the size people start to feel M 3.0 this one released 12× 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.
