Mineral, Virginia 2011 M 5.8 1,100,000× the energy of this one
Magna, Utah 2020 M 5.7 810,000× the energy of this one
Around the size people start to feel M 3.0 72× the energy of this one
This earthquake M 1.8 about 13 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.

For this area

No earthquake of M4 or more has been recorded within 50 km since our catalogue begins in 2016.
